Кабельные хроники



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.



Именно в это время года мы вновь пересматриваем наши прогнозы относительно того, какие тенденции в области тестирования станут наиболее популярными в грядущем году.

Вне всяких сомнений Интернет вещей (IoT) останется основной движущей силой во всем, что касается кабельных сетей, — начиная с локальных сетей, в которых все большее количество устройств будет использовать медные витые пары, и заканчивая центрами обработки данных, где по-прежнему увеличивается спрос на высокоскоростные волоконно-оптические соединения, вызванный растущими потребностями компаний в доступе ко все большим объемам данных, их передаче и хранении.


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.
