Testing Cabling With MPO Connectors – What’s New?

With the wide variety of standards relating to fiber optic cabling, the absence of published standards for testing fiber optic cabling terminated with MPO connectors might come as a surprise. Finally, a technical report (TR), written by this author, is scheduled for a June 2017 publication that provides such testing guidance - it is TR/IEC 61282-15. A technical report provides guidance on a subject but does not have requirements (e.g. no “shalls”) as an international standard or an ANSI/TIA standard would.

What’s All the Buzz about Limited Power Certification?

 

You maybe have heard the recent buzz about LP-certified cable for power over Ethernet (PoE) applications and be wondering if you need this cable for your PoE installations. Let’s take a closer look at this new UL certification, its relationship to the 2017 National Electric Code, why it was introduced and why you still need to test.

How to Test Shield Integrity?

Back when Wolfenstein 3D was all the rage, we set up an exhibit at a BICSI conference where we tried to make a Cat 5 link fail by inducing noise onto it. We tried all kinds of no-no’s, such as placing the cable next to a fluorescent ballast, a large electric motor, and even the coil of a running car’s engine, yet the link provided virtually error-free 100BASE-TX performance. At that point, it didn’t seem like there would be much benefit for screened cable for the vast majority of installations.

The Road to a Category 8 Cable Tester

On January 23, we announced the DSX-8000 CableAnalyzer™, the first true Category 8 tester.  You may be wondering what is required for a “true” Category 8 certification tester and why we launched it now.

Tips to Identify Copper Clad Aluminium (CCA) Cables

 

So you came across some Category 6 cable available online for practically half what you've been paying for that brand name. It claims TIA-568-C compliance, includes the UL listing mark and even has a ETL verification legend printed right on the cable. Before you get too excited, you might want to make sure that cable isn't made with copper clad aluminum (CCA).

Goodbye 2016. You Weren’t ALL Bad

 

All over the news and social media, 2016 has gotten a pretty bum rap.

With everything from shootings, terrorist attacks and the weirdest presidential election in history, to exploding cell phones, scary clown threats and numerous celebrity deaths, 2016 has been denoted as the worst year ever.

How to Save Money and Time in Testing Fibers with SmartLoop

The only way to get correct values when performing Tier 2 testing of duplex fiber links with an OTDR is via bidirectional testing that averages the measurements taken from both ends of the link.

Bidirectional testing used to involve testing the fiber from one end, walking the OTDR to the other end to test again and then averaging the two values to get the results—and it had to be done for each link.

Testing New Cable Tester in 2017

 

It's that time of year again when we take a look at what we predict to be next year's biggest trends in testing.

Obviously the Internet of Things (IoT) will continue to be a major driver in all things network cabling--from the LAN where we will see more devices than ever residing on copper twisted-pair network cabling, to the data center where demand for high speed fiber links continues to expand as companies are faced with the need to access, transmit and store more data than ever before.
