Como aplicações de fibra de alta velocidade estão afetando o campo de redes

In last week’s blog, we took a Closer Look at 40 Gig Duplex Multimode Applications, just one of the many ways that today’s data centers are cost-effectively achieving increased bandwidth in switch-to-switch fiber links. And when we say many ways, we literally mean many.

Uma análise mais aprofundada em 40 aplicações multimodo Gig Duplex

 

There’s been a lot of talk in the industry surrounding solutions capable of running 40 Gig Ethernet over duplex multimode fiber—especially with OM5 wideband multimode fiber (WBMMF) now recognized within industry standards that specifies wavelengths between 840 and 953 nanometers to support wave division multiplexing (WDM).

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.

Por que toda a agitação sobre a certificação de potência limitada?

 

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.

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.
