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.
Send us the trace file, better, please send it to us in the native, .flw, format. There is a lot of information in there that is very helpful to us, such as, what tester you are using, what firmware it has, and, what the failure is.

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.

Equipment cords are an integral part of any network—whether it’s a fiber jumper used to make connections between fiber patching areas and switches in the data center or a copper patch cord out in the LAN to connect end devices to the work area outlet.

It seems like just yesterday we were talking about spring cleaning, and now we’re moving into the dog days of summer. And it’s hot.
