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).

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.

'Twas the night before Christmas when all through the LAN, 
the channels were tested except for the SAN.
MPOs easy with MultiFiber™ Pro,
gave me hope I'd be done before fallen snow.
With SmartLoop letting me to test from one end,
I knew that I'd soon start my weekend.

每年的这个时间,我们总是会预测下一年测试领域的最大发展趋势是什么。

显而易见,物联网 (IoT) 将仍然是所有网络布线的主要驱动力—包括从LAN到数据中心的各个环节。对于LAN,我们将会看到比以往任何时候都多的设备仍然使用双绞线铜缆网络布线;而数据中心要求高速光纤链路,并且随着企业需要访问、发送和储存的数据越来越多,将随之扩展。

It felt like a Monday morning when the call, actually an e-mail, came in.“I think my DSX is broken!”As you know, they are really tough machines and, when it looks like the Fluke is wrong, usually it isn’t.

“What makes you think it is broken?”I asked, “How does this failure manifest itself?”

“The tester is failing links that used to pass.”

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?

There is much to be thankful for in our industry these days as market growth continues to be fueled by the IoT and big data driving the need for LAN and data center upgrades.
