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 2017 BICSI Winter Conference wrapped up last week in Tampa where thousands of ICT professional from around the world had a chance to gain valuable industry knowledge and check out the latest products from nearly 180 vendors in the exhibit hall – including our new DSX-8000 CableAnalyzer.
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).
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.
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.
Chegou novamente a hora de apresentar nossas previsões para as maiores tendências em testes no próximo ano.
Obviamente, a internet das coisas (IoT) continuará sendo uma grande impulsionadora no cabeamento de todos os tipos de redes - desde LAN, onde veremos mais dispositivos do que nunca conectados por cabos de par trançado de cobre, até centros de dados, onde a demanda para cabos de fibra de alta velocidade continua a crescer - à medida em que as empresas enfrentam a necessidade de acessar, transmitir e armazenar um volume de dados sem precedentes.
You have just made a loss measurement using an Optical Loss Test Set (OLTS). The measurement was made to a test limit, the result was a PASS, and the margin was provided. Have you ever thought about how much margin is acceptable?
