A wire map test may seem like the most basic test for copper network cabling and therefore one of the least important, but it is actually one of the most critical. And while the pair colors of blue, orange, green and brown might help you pass wire map testing, the test itself really doesn’t care about color at all.

Let’s take a closer look.

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).

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.

'Twas the night before Christmas when all through the LAN, 
the channels were tested except for the SAN.
MPOs easy with MultiFiber™ Pro,

With SmartLoop letting me to test from one end,
I knew that I'd soon start my weekend.

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?
