In the spirit of the season and that “Sound of Music” favorite by Julie Andrews (that some have dubbed a holiday classic), we thought we’d take a moment to wish everyone Happy Holidays and Best Wishes for a Prosperous New Year and share with you a recap of some of this years’ favorite Cabling Chronicles (yes, it is sung to the tune of “My Favorite Things.”)

There’s no doubt that the European Union has a lot of rules and regulations—something frequently pointed out by those who campaigned for a Brexit vote in the United Kingdom. And many joke about some of the more ridiculous ones, like the law that prohibits people from eating pet horses, or the one that prohibits manufacturers of bottled water from labels suggesting that consumption could fight dehydration. (Since when didn’t water fight dehydration?)

A fusion splice is when two fibers are fused together using an electric arc. Often used with pigtails for connecting 250-micron outside plant fiber to 900-micron inside plant fiber at the building entrance, fusion splicing is achieved with a fusion splicing machine after the fiber is properly cleaved with a precision cleaver. Fusion splicing can be done for a single fiber or for 12-fiber ribbon cable via mass fusion splicing that splices all 12 fibers at once.

The much-anticipated higher levels of PoE have been quite the buzz in the industry. Now that the 802.3bt standard for PoE that includes Type 3 and Type 4 PoE is expected to be ratified early next year, we will start to see more devices forego their AC power connection for PoE.

I had a fun tech support call the other day that I think you will find interesting. A customer sent one of the ugliest traces we had seen in a while. “Help! What is going on here?” This came with the usual, it is urgent, his boss will kill him, the network is down, and he saw a dog and a cat making friendly on the way home from the job site.

Fiber to the Desk (FTTD) applications have long been lumped in with other FTTX applications with the “X” signifying a variety of fiber optic access points, including Fiber to the Home (FTTH), Fiber to the Premise (FTTP), Fiber to the Curb (FTTC) and Fiber to the Building (FTTB). But it’s important to remember that FTTD is a premise application while many of the others are considered outside plant.

While the number of hyperscale data centers in the world is only estimated at around 300, with half of these belonging to U.S.-based companies (Think Amazon, Google, Microsoft, Facebook, Ebay and Twitter) and another 100 hyperscale data centers expected by the end of 2018, we are constantly hearing rumbles about these unique spaces.
Plus, hyperscales tend to be key drivers behind data center technologies, trends and applications—not to mention standards development. Would the IEEE really be working on 400 Gig if it weren’t for these giants?

We all know that dirty fiber connector end faces can cause loss and reflection, which is why they need to be cleaned and inspected before making that final connection. But what if you’ve properly cleaned and inspected the fiber end face for contamination, tested it using the FI-7000 FiberInspector Pro, and the connector still doesn’t pass muster? Maybe, just maybe, you have a connector end face that doesn’t meet end face geometry parameters.
