Re-Cabling Your Data Center Part #2

2011-05-27T13:00:00.006-04:00

In today's post we will discuss the upgrading of your data center infrastructure.
OK you made the decision, you are going to upgrade the optical infrastructure of your data center, and it is time to start planning. There is a lot to cover, knowing that in most instances the “D” word will be involved (DOWNTIME). Staying focused on the proper goals is the best bet to stay on track. So what should you be thinking about for this re-cabling job? The answer to these questions can ensure you stay on track, so it is critical to think about the following points.

Design is the first important aspect. Use the TIA-942 standard as a guideline. I would highly recommend purchasing and researching this document. It offers a roadmap for your infrastructure that will allow for growth and scalability. A well designed infrastructure will allow hardware upgrades, even with currently unheard of connector types. It will also make adds, moves and changes much easier. The basic principle is to create a structured environment where patching can be done in the “front” of the equipment racks and/or cabinets, and then trunking cable is run from the equipment cabinets to an area referred to as the MDA or Main Distribution Area. This is where all the patching can be done, without having to lift a floor tile or dig around in overhead conveyance!

Once you have the proper design that can last for generations of hardware, now you need to ensure the performance of the product you put in backs this up. In other words, it will be pointless to do this re-cabling job if the products you install won’t support the next generation of hardware. For an optical infrastructure the most important issue is insertion loss. Insertion loss is the amount of light (measured in dB) that is lost from the transmitter. Loss budgets shrink as data rates go up (insert chart). Look for products that have low insertion loss. Research what the standards are, who exceeds them and also how they are measured. There are a lot of “smoke screen” tactics, such as using average insertion loss versus maximum insertion loss. The average does not help you a bit, because you may get an assembly that is on the high side. Ensure that the products maintain these insertion loss standards after multiple uses. Demand documentation on these repeatability factors and insertion loss characteristics.

So you have a good design, and products that will last for the next few generations of hardware upgrades. Now you need to make sure things will look nice and STAY looking nice. Manageability; much of this is about planning ahead, and not allowing the “band aid” fix (the old 10 meter jumper patch for a 3ft distance). It is easy to blame a tech for this, but did they really have what they needed? Cables seem to become an afterthought. Also examine the product sets themselves. Will they work with your rack and cabinet infrastructure? Do they align with other industry standards? Are the product sets adding un-necessary cable bulk?

Lastly, respect layer one. Think about cabling when any changes are being planned for and also plan for changes on the fly. Have a small inventory of jumpers; vary the lengths so you are prepared. Are the product sets based on industry standard connections or are they proprietary? You don’t want to end up in a position where you have only one source for a connector or interconnect point. Also look at the warranty; does the warranty require a manufacturer specific “end to end” scenario, where if you use another manufacturer’s product your warranty is nullified?

If you keep these factors in mind, it should really help you to create a positive legacy. You probably inherited a cabling mess, ensure that you left a cabling masterpiece!

Re-Cabling Your Data Center Part #1

2011-05-20T10:59:00.001-04:00

In the first of a multi part post we will be exploring the key reasons data center managers should consider and how to implement a comprehensive approach when re-cabling their data centers.
Re-cabling the optical infrastructure in your data center is a daunting task. There are so many factors to think about, and that is just dealing with the physical cabling! There are other factors that must be negotiated. Typically this job will involve some amount of downtime for the data center. That adds on a lot of planning, politicking and action items. Best practice tells us to start at the beginning and move forward from there.

The "beginning" is examining WHY this may need to be done in the first place. If this is kept in mind, the goals of the project can be met and it really shouldn’t hurt that bad…

One of the major reasons the upgrade is needed is the rapid demand for more and more enterprise storage. What started with a few servers and possibly a mainframe a decade ago has now looks like a junkyard of hardware from various manufacturers that are tied together with an assortment of point to point fiber jumpers that an archeologist would have trouble separating.
Don’t take it too personally; most of us didn’t see this amount of growth coming. Enterprise storage has grown 30% year over year for the past 5 years! It’s not finished either; it is projected to grow at the same rate for the next 5 years as well! To handle all these storage needs, a cabling infrastructure must be modular and scalable. Running jumpers from point to point (directly connecting from one piece of hardware to another via duplex fiber optic patch cord) will simply not work.

Another reason is global IP traffic. This is expected to quadruple in the next four years. Video is one of the key factors here. People are visual, and video is so effective for so many business drivers (not to mention those funny or cute videos) that there is little chance of this demand shrinking. An optical infrastructure will need to handle the massive bandwidth required. Think of plumbing for this example. The typical fiber infrastructure will have a hundreds of “small pipes” running in every direction. These have come from years of smaller hardware upgrades where the old cabling could not be disturbed in fear of causing an outage. This has been the vicious cycle of the data center fiber optical infrastructure.

There are other issues that are prevalent as well. Unreliable cabling is a big culprit for “random” downtime… These always tend to happen at the worst times. Fiber optic assemblies may all look very similar, but there are so many shortcuts that can be taking the manufacturing process that degrade the quality of the cable, yet are completely unseen to the naked eye…. Like ticking time bombs, just waiting to be unplugged and then plugged back in and. SNAP, broken fiber at 2PM on a Saturday right before your daughter’s birthday party…

There are more reasons, but these are the major and most common ones. The next topic to address will be what to think about when planning for this job.

Ever Wonder - Parallel Optics

2011-02-11T07:29:00.001-05:00

With the advent of the IEEE 802.3ba standard for 40/100G Ethernet, it is important for anyone in the optical structured cabling field within the data center to understand what parallel optics is, how it works, why it will be used and potential obstacles to overcome. In a recent CABLE Talk Josh describes the Parallel optics in greater detail.

How it works: It works by sending a signal from the transceiver over multiple fibers instead of single fibers (using RX and TX respectively).

Why it will be used: Current optical technology does not allow from transmission much over 10G speeds using LOMMF (Laser optimized multi mode fiber). It can be done with single mode fiber however the costs will be much higher. Parallel optics offers a compromise of cost and use of potential existing data center infrastructure cabling.

Potential obstacles:

Use of the MTP®, in the data center this connector with either 12 or 24 fibers will need to be utilized.

Insertion loss, as data rates increase insertion loss budgets decrease. Be mindful of your loss budget and ensure any cabling investments are researched with loss budget as critical criteria.

40/100 G - Parallel Optics

2011-02-08T10:37:00.000-05:00

In this edition of CABLE Talk JT dives into parallel optics. With the recent ratification of the IEEE 802.3ba standard for 40/100 G Ethernet, parallel optics will be utilized for short reach data center applications.

Typically used in data center structured cabling environments running high speeds of 10G or even 40 or 100 Gigabit Ethernet, SAN (Storage Area Networking), Fiber Channel, FCOE (Fiber Channel Over Ethernet) with such manufacturers as Cisco, Brocade, EMC and others. Typical applications could be virtualization or internal cloud core data center applications. MTP® is a registered trademark of US CONEC.

From BICSI Orlando - Fiber Cleaning

2011-01-28T07:19:00.001-05:00

Continuing with my thoughts from the Orlando BICSI show...

One of the many classes that I attended focused on fiber cabling, performance and the importance of clean fiber end-faces as it relates to performance. Most common contaminants on fiber connectors are carbon particles, skin oil and fibrous materials. When cleaned properly and mated, there is not a chance for harmful contamination UNLESS unplugged – so when it is clean, don’t mess with it.

You should scope at about 200x, you don’t want to go too close as it may cause you to miss contaminates on the outside that could migrate in. TIP: Use a mirror to test for wet cleaners, clean mirror, apply cleaner and see residue if you see residue steer clear. This class was presented by Harvey Stone a gentleman I can best describe as passionateabout end face cleaning and inspection... he had many great analogies and stories about the importance of this subject.

Check out CABLExpress.com for more information on fiber optics and fiver cleaning solutions.

From BICSI - MTP in the DataCenter

2011-01-25T15:02:00.002-05:00

Just returning from the BICSI show in Orlando I thought it would be a great time to review my thoughts on what is happening in the world of data center cabling.

This year in the area of MTP / MPO cable connectivity (an area CABLExpress has been a leader in since 1998) it was great to see the general acceptance of the MTP / MPO connector in the data center. Several companies have announced or launched MTP / MPO cabling solutions in anticipation of rapid acceptance of the 40/100 standard. CABLExpress was a leader in this area announcing a 40/100 solutionin July of 2010 that was also backward compatible with it's Skinny-Trunk ™ Solution. It not only looks like the MTP / MPO connector is here to stay, but its roll in datacenters will continue to grow with an increased emphasis on performance.

In Fridays post I will be sharing some interesting points relating to the importance of clean fiber enfaces in the performance of your infrastructure.

The HDMI 1.4 Ethernet Channel

2010-12-19T10:30:00.000-05:00

In the last two posts I have provided an overview of the new HDMI Version 1.4 standard. In this post I will focus in on what I see as a key future looking feature of the standard, the "Ethernet Channel".

With more and more entertainment devices IP enabled, having the ability to connect to the internet, cabling is becoming more and more and issue. Currently each device that connects to the internet requires its own unique internet connection as well as a connection back to the viewing (TV) device.

The implementation of the HDMI Version 1.4 standard now allows HDMI Version 1.4 enabled devices to share the internet connection as well as traditional HDMI Audio / Video signaling in one cable. This helps to further simplify your entertainment systems by eliminating the need for separate Ethernet cables.

To maximize the value of HDMI Version 1.4 and maximize your functionality you will need to make sure your devices are HDMI 1.4 Ethernet Channel capable. Over the next year or so more and more devices will come designed to this standard as a matter of course, for now it is found in most high end devices.

Again the key benefits of the HDMI Version 1.4 Ethernet Channel are:

Consolidation of HD video, audio, and data in a single cable
Enablement of high speed bi-directional communication
IP-based applications over HDMI
Transfer speeds up to 100 Mb/sec

HDMI Version 1.4 Whats New?

2010-12-16T09:31:00.002-05:00

In my last post I introduced the different types of HDMI 1.4 cables supported by the new standard. HDMI has managed to become the de facto standard for entertainment device connectivity for three main reasons: Performance, Simplicity and Reliability. In this post I will cover some of the major changes in and advantages introduced in HDMI Version 1.4.

To sum it up Version 1.4 cables are backward compatible with 1.3 devices. However Version 1.4 allows you to be prepared for new devices with ever growing features. There are seven (7) significant areas of change addressed in the new standard.

4k Support - Allows for significantly higher resolutions of 4096x2160 vs the 1080i/p standard currently in place.
3D Support - Defines I/O protocols for 3D formats which will allow for true 3D gaming and 3D home theater applications.
HDMI Ethernet Channel - Adds a High Speed (100mbps) Ethernet channel paving the way for IP enabled devices. (more on this in a future post)
Audio Return Channel - Allows for upstream audio data to a surround sound system.
Content Type - Real time signaling of content type between your devices allowing your system to optimize settings. (IE: picture size)
Additionally. the standard allows for new "Mini HDMI" Connector Types and the addition of additional "Color Spaces" to support computer graphics and digital photography.

Keep in mind that your electronic devices must support these features adding the cable alone will not add them.

HDMI 1.3 vs 1.4 Whats the Difference?

2010-12-14T16:13:00.000-05:00

During this holiday season I am being crushed with questions relating to which HDMI cable should I be purchasing to support my many new electronic toys? All I can say is I wish the answer was clear and simple...

That said with the release of the new HDMI 1.4 specification, there are now five HDMI cable types to choose from, each designed to meet a particular performance standard. Below is an overview of the HDMI cable types, (from the HDMI.org web site) their capabilities, and how to tell them apart.

To help consumer and clarify cable types further, all HDMI cable products will now be required to be labeled by cable type. Look for these labels when choosing the HDMI cable that is best for your needs.

The secret here is to check for the HDMI Type on the product you have purchased to make sure you have the correct cable for the product you have purchased.

HDMI Cable Types

	Standard HDMI Cable The Standard HDMI cable is designed to handle most home pplications, and is tested to reliably transmit 1080i or 720p video – the HD resolutions that are commonly associated with cable and satellite television, digital broadcast HD, and upscaling DVD players.
	Standard HDMI Cable with Ethernet This cable type offers the same baseline performance as the Standard HDMI Cable shown above (720p or 1080i video resolution), plus an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.
	Automotive HDMI Cable Designed for internal cabling of vehicles equipped with onboard HD video systems. Tested to a more robust performance standard, and capable of withstanding the unique stresses of the motoring environment such as vibration and temperature extremes.
	High Speed HDMI Cable The High Speed HDMI cable is designed and tested to handle video resolutions of 1080p and beyond, including advanced display technologies such as 4K, 3D, and Deep Color. If you are using any of these technologies, or if you are connecting your 1080p display to a 1080p content source, such as a Blu-ray Disc player, this is the recommended cable.
	High Speed HDMI Cable with Ethernet This cable type offers the same baseline performance as the High Speed HDMI Cable shown above (1080p video resolution and beyond), plus an additional, dedicated data channel, known as the HDMI Ethernet Channel, for device networking. HDMI Ethernet Channel functionality is only available if both linked devices are HDMI Ethernet Channel-enabled.

Separating the Spin From the Standards – Part 2

2010-11-04T08:31:00.003-04:00

In Monday’s Blog post we started the discussion on “Separating the Spin From the Standards” as it relates to purchasing cabling products. Today we will explore how to assure you are getting high performance product while not over paying.

First, understand the standards. Some of the popular organizations are: EIA/TIA, UL, ETL and BICSI. I would recommend to start with the BICSI organization at www.bicsi.org as this group is solely dedicated to layer 1 cabling. Next would be the TIA, as this is really the standards benchmark in the industry. You can visit them at www.tiaonline.org/standards/ . You don’t have to study every part of the standards, just understand the big picture aspects.

Next, once you have an understanding about the standards and measure that against what you want out your cabling purchases (ex: must meet/exceed TIA-568-C.0). Ask this of your cable supplier(s). These standards are created to ensure your cabling system is not proprietary!

Finally, the last step is to ask for third party testing documentation. This ensures that the product will perform as the supplier claims. Don’t take anyone’s word for this.

It is really that simple, understand the standards, ask your suppliers about them and request proof (third party testing). This way you don’t have to fall for any gimmicks like the end to end cabling warranty – as those typically just lock you in to buying one product set and that is never a good scenario.

Separating the Spin From the Standards – Part 1

2010-11-01T08:30:00.003-04:00

To someone purchasing and/or recommending network cabling products; all of the standards, codes and warranties may seem like a “dark art” with no real rules or regulations. Some manufactures play to this fear offering solutions that “guarantee” performance. However, when you look at the fine print behind these “guarantees” to be protected you must use 100% of that manufactures product in the system forever.

In reality cabling should not seem like a “black art” and in reality this is not the case. There are strong industry standards, and once you know where to look you can make informed decisions about your cabling purchases. The goal is not overpaying for cabling products that meet / or exceed the industry standards. The way to do this is to learn about the standards, find what standards are important for your current and future structured cabling goals and measure those against your suppliers products sets. Most importantly verify your vendors performance by requesting third party test results.

In Thursday’s Blog post, I will break the process down into three simple steps to assure you both save money and are getting high performance product you desire.

Happy Halloween

2010-10-30T16:21:00.002-04:00

I just wanted to drop a quick note into the blog today as it is Halloween!

Big Fingers vs Tight Connections

2010-10-14T15:39:00.003-04:00

OK so I am a big guy (not huge, big) and the density of connections on fiber enclosures continues to get tighter and tighter. I think we have arrived to the point where it is almost impossible to reach in and move a connection without disturbing other cables.

Now enter a solution from CABLExpress called the "Skinny Fingers"

"Skinny Fingers" are built with a glass-fiber-reinforced nylon injection-molding compound offering excellent strength, stiffness, high temperature performance. CABLExpress has taken the time to make the tips and pivot points reinforced with stainless steel strength members for extra ruggedness. The design of this cool tool allows a firm grip on a wide variety of connectors, while guarding against pinching or crimping of the adjacent fibers or connectors "Skinny Fingers" work with virtually all rectangular or square cross-connection connectors (ie LC, MU, SC, MT-RJ) "Skinny Fingers" are lightweight and non-conducting, making the tool safe to use in environments where voltage is present.

So if you are like me and struggle with tight connections the "Skinny Finger" might be just the ticket to make your next connection easier.

How Does Fiber Type Effect Distance

2010-10-04T08:09:00.004-04:00

I am often asked are there different types of optical glass in fiber cables or are all fiber cables made with the same glass? The simple answer to this question is NO not all glass in fiber-optic cables are the same. The three main differences relate to:

Type - Single or Multimode
Core Size
Laser Optimized or Not

Laser optimized fiber cables are typically have an Aqua Jacket with a core size of 50/125 and referred to as OM3 (an EIA/TIA Standard). In August 2005 the TIA adopted a new, higher performance standard the OM4 laser-optimized standard.

What do all of these fiber types mean to you and why should you care? The answer comes down to transmission speed and distance. The chart below illustrates two different transmission standards Fiber Channel and Ethernet as well as different transmission rates. Each fiber type is represented by a color and demonstrates the distance supported by the standards.

We have committed to donate to the American Cancer Society, 5 cents from every CABLExpress copper and 50 cents from every CABLExpress fiber cable sold between September 16th and October 31st (stocked lengths only).

Customers who purchase cables this month will also receive a Cables for a Cure pin or window cling (shown to the right) to display in support of this important cause.

100% of the proceeds (approximatively $100,000 to-date) are donated directly to the American Cancer Society’s fight against breast cancer.

Simple Steps Can Save You Green in The Data Center

2010-09-20T10:43:00.000-04:00

Are you receiving high-energy bills from your power company?

There are a few simple steps you can take in your data center cabinets that will increase efficiency and lower those high energy bills. The main idea is to direct the cold air from your CRAC (Computer Room Air Conditioner) unit to the front of the server cabinets and exhaust the hot air up and back to the unit for cooling.

In the applications where air flow direction is needed, there are a few simple options that will help.

Brush grommet kits are designed for easy installation to the sides of your cabinet rails. The use of brush grommets allows for cabling to pass through the brushes but still directs the air flow to the servers.

Do you have open spaces between the rails? Fill those open spaces with filler panels that are available in a wide variety of sizes. Filler panels mount to the rails of your cabinet and are an inexpensive way to help direct the air flow where it is needed. If you are not looking to completely close that space, there is a hybrid item that acts as both a brush grommet and filler panel.

Cable management can be a simple and very effective way to increase airflow within the cabinet. Organize your cable mess and all the air to flow freely!

Take these three simple steps to increase airflow and begin seeing lower energy bills.

Layer One Gets NO Respect

2010-09-16T11:12:00.000-04:00

I have been involved in the cabling infrastructure business now for close to 30 years. During that time a lot has changed but one thing often remains the same… Layer One (specifically cabling) is often the last thing considered in an IT upgrade. Yes, whether its a cramped closet that we are stuck in and forced to use or an unplanned point to point connection in the data center… Layer One is the last thing often considered.

Its time LAYER ONE gets some respect!

http://www.youtube.com/watch?v=sYxOS5L5WzM&feature=player_embedded

This month the CABLExpress Team has started a campaign to help Layer One get the respect it deserves. Join us at AFCOM’s Data Center World Conference in Las Vegas to learn more about the importance of Layer One. We’ll help you learn how a properly designed fiber infrastructure can help save you money and future proof your investment.

Hay it’s TIME for your Layer One Infrastructure to get the respect it deserves.

New "Mini" LC Connector?

2010-09-14T17:23:00.000-04:00

That's Right there is a new fiber connector on the market...

Brocade has developed the FC8-64 high density 64 port blade for the DCX Backbone family. 64 ports in one module! How do they manage to get that many fiber ports in that small piece of real estate? By developing a new SFP…. Called the mSFP. The “m” stands for mini. It’s cable counterpart is the mSFP cable assembly or mini-LC.

To the naked eye, this mSFP and mini-LC look identical to a standard LC. Under closer scrutiny it is not. The “pitch” is 1mm closer than a standard LC. While a "small" change it makes a "Big" difference in density!
The new ‘tight pitch’ LC assembly is also referred to as the mSFP or mini Small Form factor Pluggable. The pitch is defined by the on center distance between ferrules of a duplex LC. These picture below illustrates this. The connector with the black housing is the Mini LC, they beige is a standard LC.

Regular LC duplex pitch distance is 6.25mm
New mSFP duplex pitch distance is 5.25mm

Currently there are no patch panels that accept this form factor. In order to use this module in accordance with a TIA-942 structured cabling system you must purchase a hybrid cable. Contact CABLExpress to order or obtain more information on this product.

USB! Who? Me?

2010-09-03T14:51:00.000-04:00

Special thanks to guest contributor Brittany Szulis for this post.

There are certain products in the industry that are so simplistic sounding yet, they can be confusing little buggers. USB cables fall under this category for me. Anyone else? In my opinion, USB cables are such a minuscule product, but the truth is we use them everyday so let’s get to know them shall we? *I did what any young professional would do and I went to Wikipedia to see what USB stood for first of all. And here she is, The Universal Serial Bus (USB) is a standard for peripheral devices. It began development in 1994 by a group of seven companies: Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel. USB was intended to make it fundamentally easier to connect external devices to PCs by replacing the multitude of connectors at the back of PCs, addressing the usability issues of existing interfaces, and simplifying software configuration of all devices connected to USB, as well as permitting greater bandwidths for external devices. The first silicon for USB was made available by Intel in 1995.[

Thanks for the confusion Wikipedia…Blah, blah, blah…What the heck are they all used for? That is what matters after all.

*USB A Male to A Male Cable: The “Straight forward”. Use for hard drive enclosures, printers, modems, cameras. Ok, that wasn’t SO bad.

*USB A to 4-pin Mini-b Cable: The “Lost and Found”. A practical replacement for a lost cable and excellent to keep as a spare. Use for many digital camera models, cell phones, MP3 players, PDAs and other mini-USB devices. Hey! I love taking pictures!

Fiber Optic Field vs. Factory Termination – You decide!

2010-08-16T08:17:00.014-04:00

There are several advantages and disadvantages to field terminating your fiber. When I’m done, you can decide where to spend your money. There is little planning involved when it comes to field terminating. It promotes easier cable pulls between buildings. Little slack storage is involved. Now, let’s scrutinize what this means for YOU. You can bet to see higher labor costs, long installation time, and even inconsistent terminations that can cause signal loss in your network. The equipment to field terminate is costly, and did I mention higher labor costs? In today’s industry, maximizing your dollar can certainly go along way. What else am I missing? Oh yes, inaccurate test results! Would you drive a car one million miles with unreliable brakes? Didn’t think so. So let’s be smart about Field vs. factory termination.

http://www.youtube.com/watch?v=OA4ohhl33Mk

Factory termination without doubt has great advantages, with a little bit of planning ahead and money in your pocket you can be guaranteed with factory terminated trunks you will get a reliable product, it’s fast, it will drastically reduce install pricing, top notch standards are delivered to your door, less space is used, cable management almost becomes obsolete with factory terminated trunks.
I’ll let you decide the right method, but take into consideration CABLExpress is designed to help customers choose the most effective methods to use inside Data Centers to help keep costs down and the network up, we recommend factory termination.
Will you recommend it?

Josh gets WET explaining Fiber Core Alignment

2010-05-25T13:47:00.002-04:00

In another edition of CABLE Talk JT explains the importance of core alignment and what happens if cores are not matched.

The twist in this edition is JT becomes VERY wet when his example of misaligned fiber cores gets a bit out of control.

This is a funny edition of CABLE Talk you won’t want to miss or for that matter share!

Cable Talk #13

CABLExpress Add VISIO Shapes to Ease Design

2010-05-19T09:43:00.000-04:00

Microsoft Visio is an easy to use yet powerful tool for cabling infrastructure design.

For years it has been the “go to” program for data center structured cabling design. It has gained popularity in recent years due to the importance, and need for a cabling TIA-942cabling design. CABLExpress now offers Visio stencils of the extensive data center structured cabling products like the H-Series fiber enclosures, RSD fiber enclosures and copper trunking panels. This addition puts you on easy street, speeding your ability to specify and design the best implementation of your infrastructure.

Since the TIA 942 calls out for modular scalable products, the stencils meet that criteria. All parts that interoperate in real life are able to do so in the stencils. This allows the user to have a visual design that is more time effective and can help reduce errors in RFQ’s due to its visual nature.

If you would like to download these stencils for free click here

High Density Fiber Harness Application

2010-04-12T15:04:00.001-04:00

In this edition of CABLE Talk JT goes over the Skinny-Trunk Harness and Z-Mount bracket's features and benefits in cabling up large Cisco and Brocade switches with high performance fiber in a structured cabling data centers.

This CABLE Talk is a good follow on to Episode #11 where he did a time laps demonstration of how to apply the solution in the field.

Full Vs Half Duplex

2010-04-09T15:11:00.002-04:00

Full vs Half duplex...

In the world of digital communication, full-duplex means that a system or circuit is capable of both transmitting and receiving data at the same time. In contrast, half-duplex means that communication can only go in one direction at a time.

A good analogy is comparing telephones to walkie-talkies; phones are full-duplex, and walkie-t4/9alkies are half-duplex.

RoHS

2010-04-06T09:44:00.000-04:00

RoHS is an environmental protection regulation that has been enacted by the countries of the European Union and widely referred by to by other countries. The regulation prohibits the use of certain toxic chemicals in the manufacture of electrical and electronic devices. Tiny amounts of lead, mercury, cadmium, and other chemicals have been used in the past to build circuit boards and other electronic components.

Now, manufacturers are switching to greener, less dangerous materials and processes in order to comply with the new regulation. CABLExpress is vigilant to make sure that our products adhere to the RoHS standards.

LC Connector

2010-03-29T08:33:00.002-04:00

The LC connector is a Small Form Factor (SFF) connector for fiber optic cables.

Developed by Lucent (LC stands for Lucent Connector), it has gained wide acceptance by manufacturers of 10 / 100 Gigabit optical transceivers. LC connectors have a squarish shape, and are usually held together in a duplex configuration by a plastic clip.

S-Video Configuration

2010-03-25T13:28:00.001-04:00

An S-video signal is made up of two parts—luminance and chrominance.

The luminance signal (usually abbreviated as “Y”) carries greyscale brightness information, which is basically black-and-white video.

The chrominance signal (abbreviated as “C”), carries color detail information.

Because the two lines are separate, more bandwidth is available and S-video provides a better picture than composite video, where all information is carried on one conductor.

VGA Signal Distance

2010-03-23T09:23:00.002-04:00

What’s the maximum distance that a VGA signal can travel?

There’s not a firm, exact answer to that question. Much depends on other factors, such as the quality of the source & display, the installation environment, the preferences of the audience, and the quality of the cable.

For long runs (50 feet and longer), a booster is recommended to compensate for the distance.

Ever Wonder? Fiber Core

2010-03-20T07:19:00.001-04:00

Did you know how small the glass core is in a fiber optic cable? Singlemode fiber cables have a glass core diameter of 9 microns, or 9 millionths of a meter.

By comparison, the copper conductors used in most network cables (24 AWG wire) is over 500 microns thick, and the thinnest human hair (blonde, by the way) is about 20 microns thick.

Ever Wonder? Velocity of Probagation

2010-03-18T09:12:00.001-04:00

The material used to make up a coaxial cable’s dielectric does have an effect on performance. The insulating material of a dielectric affects the velocity of propagation, or how fast the signal travels down the wire. Also, a dielectric should be stiff enough to hold its shape when bent or flexed. Any deformity in the shape of a coaxial cable’s dielectric affects impedance, which can create return loss.

Quality cable assures you will have the signal level you need when you need it. All cables do not have the same performance qualities.

Ever Wonder? TCP/IP

2010-03-16T13:07:00.000-04:00

The communications protocol that the Internet runs on is called TCP/IP. What’s a protocol? It’s a set of rules & standards that devices use in order to talk to each other.

One of the benefits that the TCP/IP protocol provides is that a message can take many different paths in order to reach its destination. This feature was developed because the US Department of Defense wanted to make sure that military assets could always communicate with each other in case of nuclear war.

Show Season - AFCOM

2010-03-11T16:34:00.002-05:00

I am one of those people who enjoys the opportunity, (however crazy it makes my schedule) to get out to the many conferences that happen each spring. These events present unique opportunities for me to meet with clients, vendors and most importantly see and learn about what is happening in our fast paced industry.

It has been a while since my last blog posting, however, spring is one of the busiest and most interesting times of the year for me. If is it Spring it MUST be conference season!
This past week I returned from AFCOM’s Data Center World conference in Nashville. AFCOM is the leading association covering data center management. This year’s conference was strong despite the soft economy, this demonstrates the importance the role the data center plays. Hot topics were energy issues, including generation and backup power as well as how to cooling the data center efficiently. Speed, density and management of the ever growing data processing and storage needs were among the topics I honed in on most attentively.
The week of the 22nd I am off the San Diego CA to the Optical Fiber Conference. This conference covers the latest in fiber optic technologies. Understanding what’s new and more efficient allows CABLExpress to continually evolve our product sets.
Look for my tweets from that show and a blog update when I return.

Ever Wonder? Ethernet

2010-02-09T09:00:00.001-05:00

Ethernet is the most popular communication protocol used for computer networks today. In Ethernet communication, information is broken down into small packets and then sent from a node (usually a computer) out to the network.

These packets are re-assembled at the target into the original message. Current Ethernet speeds can reach 1000 Gbps, or 1000 million “1”s and “0”s per second.

Copper Trunking Saves Both Time and Money

2010-02-05T08:55:00.001-05:00

This article was contributed by Brittany Szulis

Looking for a quick and easy way to clean up that cable mess you put on your “To-Do” list? Let CABLExpress give you a few pointers. Copper Trunking is the latest and greatest way to run CAT5e and CAT6 cabling through your Data Center as well as network closets. The simple idea behind Copper Trunking are the factory terminated ends to create an easy installation process, when the bundled cabling is used in conjunction with a modular patch panel system it cuts down on install time by 80%. Since the 110 punchdowns are done for you in our factory, excellent time and cable management are going to be a great benefit. You can choose from a multitude of options to pick the right trunk for your data center.

So what is a copper trunk?

A copper trunk is a preterminated copper bundle held together by a durable sheathing for quick adds, moves and changes within your Data Center. The trunk makes it easy to pull through racks, cabinets, under or above the floor or ceiling. You can choose from riser or a plenum rated jacket, CAT5e or CAT6, staggered ends for extra cable management in a row, and we can build virtually any length! Start planning today and get CABLExpress involved. If you are confused about length let us know and we can assist. Measure from each point that the copper trunk will be running through and always add 10% for bend radius and corners! Contact anyone on the CABLExpress team today and find out how you can save time and money in your Data Center.

To get a better idea how to apply / measure a copper trunk check out this YouTube video.

Ever Wonder? Cable Capacitance

2010-02-02T08:10:00.001-05:00

Capacitance is an electrical property that refers to the capability to store an electrical charge. A capacitor is constructed of two conductive materials separated by an insulator, or dielectric.

Capacitance is a concern in cabling, because all cables are, in a way, long capacitors. This can affect the signal that is being transmitted down the cable, so manufacturers seek to control capacitance in a variety of engineering techniques.

Fiber trunking; It’s NOT hip to be square!

2010-01-29T08:49:00.000-05:00

This post was contributed by Josh Taylor.

When it comes to fiber optic trunking, there are two major options for overall construction loose tube (round) or ribbon (square). We believe that the loose tube construction is the bestoverall for most cabling applications. The design lends itself to distinct advantages that make the choice clear to us.

The loose tube construction, being round, can bend on 3 axis points (any which way). The ribbon cable, because of its square nature, has a preference to bend on axis only. If bent on the “unnatural” axis, heavy insertion loss occurs which can lead to a myriad of problems on the network. This also makes routing very difficult at times, and forces the installer to bend on the unnatural axis. Loose tube design bending on 3 axis allows easy cable routing and takes away the danger of insertion loss due to improper bending. Due to the round shape, the loose tube construction will displace crush force much more efficiently than the ribbon.

Years ago ribbon cable first boasted the highest density of fibers. This is no longer the case, as now most loose tube designs boast a 25% smaller footprint than ribbon designs.

CABLE Talk - Measuring Copper Trunks

2010-01-27T14:04:00.000-05:00

In this edition of CABLE Talk Josh and Brittney demonstrate the advantages of preterminated copper trunking. In addition Brittney discussed how to properly measure trunking in your data center.

What is LSZH?

2010-01-20T10:55:00.001-05:00

Plenum-rated cables have been around for a long time. These are cables that are built with a jacket material that is designed to give off low amounts of smoke and toxic gas, and retard flame travel. Recently, new jacket materials have been developed with the description, Low Smoke/Zero Halogen, or LSZH. These new cables give off even fewer toxic and caustic fumes than plenum-rated cables. They are not currently found in widespread use in North America, with applications limited mostly to government, military, and aerospace industries.

PCI vs PCI Express

2010-01-18T11:45:00.000-05:00

Historically one of the most common expansion interface found on PC motherboards was the PCI slot. PCI stands for Peripheral ComponentInterconnect. The technology was developed by Intel in the early 1990’s, and it quickly became a standard throughout the industry due to its advantages over other motherboard interfaces such as ISA and VLB.
The newest evolution in expansion interface technology is PCI Express, which uses different signaling and physical connections than PCI. PCI Express has effectively replaced the PCI standard

Why? BNC Connectors in Pro Video

2010-01-14T13:02:00.001-05:00

Ever Wonder... Why BNC connections are preferred over RCA plugs in professional video applications?

There are a couple of strong reasons. First, BNC connectors allow for much tighter control over impedance than RCA connectors. This results in a more stable picture image. Second, the twist & lock mechanism of a BNC makes it very difficult to be jarred loose accidentally. This is especially important in patching applications where A/V engineers and technicians may be working in close quarters with several “hot” video feeds

Origin of the BNC Name

2010-01-12T13:38:00.000-05:00

Ever Wonder?

BNC connectors are round plugs with a “bayonet”-style locking system, used on certain coaxial cables. BNC connectors are normally very hardy, and their locking mechanism keeps them securely in place once connected.

While there are meaning many popular theories explaining the acronym “BNC”, but the most likely is “Bayonet-Neill-Concelmann”, which refers to the two gentlemen that developed it years ago

Single / Multi Mode Fiber

2010-01-06T10:47:00.000-05:00

OK sometime I get asked questions that are I think are self evident... it's easy to forget not everyone is in the fiber business with that in mind I make this clarification.

The terms “ multi-mode” and “single-mode”, when used with fiber optic cables, have nothing to do with the number of connectors on each end. Most fiber jumpers are duplex—meaning that they have two connectors on each end. Many people that are unfamiliar with cables improperly assume that a duplex cable is always “multimode”, because it has “multiple” connectors. Mode has nothing to do with the number of connectors on a cable; it only describes the number of pathways or waveforms of light traveling inside the fiber cable itself. (refer to the image above)

Fiber Optic Polarity - Don't let it bring YOU down.

2009-12-17T08:58:00.000-05:00

There are countless stories of “nightmare” fiber optic installations. Many of the nightmares were caused from polarity issues! The concept of polarity itself issimple, the transmit needs to go to receive and vice versa. However, things do tend to get complicated when there are multiple connections involved

in the fiber pathway. This blog will explain why it is important to have a solid understanding of the polarity concept, and a way to ensure you can make a fix in the field if needed.

If you follow TIA-942 standards, you will be running light from your equipment to the MDA (Main Distribution Area) in order to manage your connections properly. Potentially, there are more coupling points in between depending on the size andlayout of your data center. You could end up with 3 to 5 connector couplings in any channel. To complicate this more, you throw in the different light path methods. There are four accepted methods - A, B, C, and D. Different manufacturers have adopted different methods for a myriad of different reasons. It is important for the end user or installer to know what these are. and especially know what you are buying as you plan out your installation. If you do not understand your light path, you can easily end up with catastrophic network failure.

In a perfect world, you should be able to connect your trunks to your enclosures and then jumper right to your equipment and have the correct polarity. Sometimes this does not happen. We offer fiber jumpers come with side release clips. This allows you to simply reverse the polarity in the duplex housing of the jumper assembly and eliminate your problem.

HDMI Problem Solver

2009-12-11T08:46:00.002-05:00

One of the big problems facing HDTV users is connecting HDMI cables into wall-mounted sets. Often, the HDMI sockets force the cables to exit in unwanted directions. A quick and simple solution is now available with our rotating HDMI adapter. It allows the user to flex their HDMI cables in any direction, making them easier to route through tight spaces behind the TV.

Did You Know - USB

2009-12-08T14:28:00.000-05:00

Did you Know the USB connector in your PC or laptop uses only two conductors to send data, and another two conductors for 5 Volt DC power and ground. This means that USB cables can be extremely thin and flexible, and the cable assemblies are very easy to manufacture. This helps keep the cost of USB connectivity down, and helps contribute to the dominance of USB as the primary interface for computer peripherals.

HDMI Specifications

2009-12-04T12:01:00.001-05:00

The latest revision to the HDMI specification is version 1.3. Because the revision defines many new features, the HDMI organization is asking manufacturers and vendors not to use the phrase “1.3” by itself when describing products. Instead, descriptions should focus on the particular features that are supported.

The HDMI specification is maintained by seven manufacturers, known as the HDMI Founders. These companies (including Sony, Toshiba, and Panasonic among others) have led the development of this high-definition digital interface that is now the de facto standard for c

HDMI - What is it?

2009-11-30T14:26:00.000-05:00

HDMI (High-Definition Multimedia Interface) is a digital connectivity technology designed for the A/V marketplace. HDMI combines digital video and audio into a single connector, so that High Definition source equipment (such as satellite receivers, cable boxes, and DVD players) can connect to HD displays with just one cable. All HDTV manufacturers are using HDMI as their interface of choice, so anyone that is buying an HDTV is also probably looking for an HDMI cable.

Fiber Ground Loops? Not

2009-10-16T18:30:00.002-04:00

One of the reasons why fiber optic cable is used to connect between buildings is because of its non-conductivity. When two buildings are connected by a cable with copper conductors, slight differences in the ground potential of each building may cause a “ground loop”, which is a form of EMI that disrupts the signal on the cable. Fiber cables carry light, not electricity, so they don’t require any copper conductors or metallic shielding. This eliminates ground loops, and provides error-free communication.

What is Up-Converting?

2009-10-16T18:25:00.002-04:00

Up-Converting is a process where a video image of a certain resolution is modified by a device to appear in a higher resolution. This function can also be described as scaling or line doubling. A typical up-converting application occurs with many Blu-Ray DVD players, which can take the image from a standard DVD (which has a 480p resolution), and interpolate it to a higher resolution, even as far as 1080p. The result isn’t a “true” HD picture, but it can still look amazingly better than your standard DVD.

Cleaning Fiber Cables

2009-10-08T09:43:00.001-04:00

We all know that fiber optic cabling is a high performance option for datacenters and network connectifivity. But, did you know that fiber cable endface contamination can quickly crash your link?

Check out this quick tutorial by Josh Taylor of CABLExpress® which shows and describes fiber optic end face inspection and cleaning. Covers: how to clean a fiber cable, how to inspect a fiber cable, how does fiber get dirty, what happens when fiber gets dirty.

What is Impedance?

2009-10-01T16:39:00.003-04:00

Impedance is an electrical property of a communications cable. It is a measure of how much the cable impedes the flow of current across the length of the wire. High-frequency signals, such as RF (TV) and analog video, require a cable with constant impedance. Variations in impedance cause reflections of the signal, which results in an anomaly called return loss.

Today I break with my normal topics on technology and cabling to bring to your attention a unique opportunity. Today Disney Parks (one of my favorite places) announced a program called “Give a day, Get a Disney Day”. This program is Disney’s way to encourage you to give back to your community.

Beginning January 1, 2010 you will be able to sign up at Disney’s web site and search for available opportunities. To get an idea of what types of opportunities are available check out the Hands On Network. There are lots of details on the program and answers at the Disney Web site including an FAQ.

At the end of the day we all should be volunteering to give back to the communities we live in... However if you needed a reason to get moving this is a great one!

Ever Wonder? Microphone

2009-09-28T11:21:00.002-04:00

Ever wonder how a microphone works? Microphones use a device called a transducer, which converts one type of energy to another. Most mics have a small diaphragm which picks up the sound energy from a source, such as a person speaking. The diaphragm vibrates, and in turn it vibrates a small magnet, creating an electrical audio signal. This signal then goes out from the mic to an amplifier, and then back out to a speaker.

Point to Point Vs Structured Cabling

2009-09-23T16:24:00.003-04:00

Despite the added time required to plan properly there are many advantages to deploying a structured cabling solution as compared to a point to point approch.

Join Josh "Cupper" Taylor for a quick tutorial which shows and describes a structured cabling system vs. a point-to-point system and the advantages.

Where were Fiber Optics 1st Used?

2009-09-18T15:14:00.004-04:00

Ever Wonder?

Fiber optic cable was originally developed for use in medical applications, such as endoscopy. However, these early fiber devices could only send signals a few dozen feet, so they were not practical for telecommunication. In the early 1970s, researchers at Corning devised a way to efficiently produce optical fibers using chemical vapor deposition. This method allowed for the construction of fiber cables up to several kilometers long, which made the technology ideal for long-distance and high-bandwidth communication. The rest is history!

What is Cable Capacitance

2009-09-08T13:08:00.001-04:00

Ever Wonder: What is Cable Capacitance?

Capacitance is an electrical property that refers to the capability to store an electrical charge. A capacitor is constructed of two conductive materials separated by an insulator, or dielectric. Capacitance is a concern in cabling, because all cables are, in a way, long capacitors. This can affect the signal that is being transmitted down the cable, so manufacturers seek to control capacitance in a variety of engineering techniques.

Don’t let the M.I.C.E. bring your network down

2009-09-02T13:13:00.000-04:00

The TIA 568-C.0 standard includes a rating system for survivability of cabling components using the acronym MICE. The acronym addresses site environmental classifications, environmentally controlled areas such as commercial building offices, light industrial environments and industrial environments. The standard includes a calculation table to measure the effects of the following conditions.

M echanical – vibration, shock and crushing factors
I ngress – liquid and dust particles
C limactic – temperature, humidity, solar radiation and chemical
E MI – Electro Magnetic Interference

Of Mice and Men
Human factors, especially in the mechanical aspect are often missed. Plugging and unplugging cables, accidental pulls and improper strain relief just to name a few. Make sure your cabling can meet these daily rigors. Ask about environmental testing procedures and find out what rigors your assemblies can handle!

Fall Trade Show Oppertunities

2009-07-30T09:14:00.000-04:00

It is not to early to start blocking your calendar for the fall learning and trad-show season. We all know that budgets are tight,but education is critical to stay ahead of ever changing trends. From a cost perspective airfare and hotel rates are a deal if you take the time to look. Additionally, most vendors who attend these shows have free guest passes don't be afraid to ask!

Two of my favorite fall shows are located one on the west coast (Las Vegas) and one in the south (Orlando). These of course are the BICSI and Afcom Data Center World conferences.

The BICSI conference kicks off in Las Vegas on Sunday September 20th and runs through Thursday September 24th. This show represents a great opportunity with a comprehensive schedule allowing you to both learn and see what is happening in the world of cabling infrastructure.

Both of these events allow you a great opportunities to expand your knowledge base and see products up close and personal.

Underfloor Cleaning = Increased Airflow

2009-07-22T14:46:00.003-04:00

In Data Center magazines, all the talk is GREEN. There are products that can lower power consumption, reduce waste and run more efficiently. Often overlooked in running a clean, efficient (or GREEN) Data Center is… Well… Cleaning!

I recently read a great article about Cleaning Under the Raised Floor. The article offers some great tips on how to approach this important but tedious job. The benefits of cleaning out under the raised floor could be monumental. The article also points out how precarious this job is. I don’t think that anyone would disagree that potential downtime is a scary thought…. In fact, that is probably the most common excuse why this job does not get done. However, if done correctly, this project could go a long way in preparing your data center for the future.

With 40 and 100 gig speeds on the near horizon, most fiber cabling infrastructures in the data center will need to be upgraded. At that point, you could have even more spaghetti under floor! That is probably reason enough to take on this task. You can even coordinate to upgrade sections of your infrastructure with Skinny-Trunk™ condensed fiber trunk solutions to help your data center run more efficiently and be ready for the future!

Data Center Copper & Fiber

2009-07-16T15:13:00.002-04:00

I recently came across an article authored by Carrie Higbie, Global Director of Data Center solutions and services. The article titled Copper and Fiber Decisions for a 10Gb/s Data Center is a interesting read.…

“In the “old days’ a few short years ago, cabling, both copper and fiber, was rather benign to data center design. Likewise, power was a necessary evil that was considered to be a cost of doing business. With green initiatives swaying decisions, power with resultant cooling needs, and upgraded cabling infrastructures are bringing facilities back into the discussions for networking gear. With varied capabilities of copper and fiber to support the higher bandwidth demands in the data center, an end to end approach to these decisions is the most cost effective approach for data center planning.” Read More

Fiber Enclosures; “Playing Nice in the SANbox”

2009-06-30T11:44:00.004-04:00

Simply put, Fibre Channel director switches are complex and costly. Data Center managers in high technology environments need the increased scalability, reliability, and fault tolerance of massive director switches such as the Brocade 48000 and Cisco 9513. These factors lead to the need for higher port density per blade, and this adds up to a lot of fiber optic cabling. Anyone in the business knows that this leads to a potential cable management disaster. This problem was the basis around the design plan of the CABLExpress Cables H series fiber optic enclosures.

One of the most efficient ways to keep the cabling manageable is to use a port emulation technique. Port emulation is obtained by creating a passive patching system directly above, or very close in proximity to the component being emulated. This allows MAC’s (moves, adds and changes) to be done in a passive environment on equipment that is less expensive and user friendly. This was the primary principle used by the CABLExpress Cables Design Team to overcome the cable management problem.

The 10U model can fit up to 576 duplex LC ports when fully loaded. This is more than enough to emulate either the Cisco 9513 or Brocade 48000. The modules also have multiple densities of 24 or 12 duplex LC port to further match the scalability of the director switches. The H Series also includes options for MTP mating in which a potential 4,608 fibers could be managed in this 10U box using a direct attach harness system.

These are impressive numbers, but is it usable? The answer is yes if you use the CABLExpress Cables Skinny-Trunk System with reduced diameter fiber trunking, custom breakouts lengths and Uniboot design jumpers.
