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.
It's that time of year again when we take a look at what we predict to be next year's biggest trends in testing.
Obviously the Internet of Things (IoT) will continue to be a major driver in all things network cabling--from the LAN where we will see more devices than ever residing on copper twisted-pair network cabling, to the data center where demand for high speed fiber links continues to expand as companies are faced with the need to access, transmit and store more data than ever before.
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.
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.
