Кабельные хроники

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.

STANDARD OR APPLICATION NOTE

In our last 101 Series Blog, we took at closer look at everything in blue at the top of your LinkWare Report. But what if your customer wants you to explain the detail and those pretty charts to the right?

Let's dive deeper so you're prepared for that possibility.

So you used your DSX-5000 to test some recently installed copper network runs for your customer. You can easily see on your tester if the link failed or passed for the application you were testing, but now your customer wants a customized report showing the detail.

It’s that time of year again with a chill in the air, falling leaves and all things spooky.

In the spirit of Halloween, we thought it apropos to take a look at two of the most confusing (and perhaps scariest) OTDR events--ghosts and dead zones.
