I once took a class where the professor would explain concepts in two ways. First, he would dive into the mathematics behind the idea, filling the whiteboard with equations and showing how they all related to one another. He tagged this “for the engineers”. Then, he would explain the concept again, but this time, with no math at all. This he said, was “for the poets”.

While most enterprise data centers see fiber counts ranging from 12 to 144, the fibers counts found in cloud and colocation data centers are much higher – typically anywhere from 864 to 1728.

This week, we announced the latest enhancement to the Versiv Cabling Certification System: the FiberInspector Pro MPO inspection camera. We thought this would be a good time to review the changes made to Versiv since it launched and how that lets you maximize the value of your investment.

In a typical week, we get more questions on our Pro3000 Tone and Probe Series than any other product. That’s not surprising, as we sell a very large quantity of these testers.

Sometimes, it seems like you need an extra hand when you’re testing. For example, when using our FI-3000 FiberInspector Pro MPO camera, you need a hand to hold the connector, a second to hold the camera, and a third to run the phone or Versiv unit and view the images. Most of the time, it’s not a big deal – for example, once you get the cable connected to the camera, you’ve got a free hand to operate the phone or Versiv. But it could help productivity in some cases if you had that third hand. Since we’re not in the prosthetics business,

Several vendors offer field-terminated plugs – both crimp style and modular insulation displacement. These plugs can be terminated to category twisted-pair cable to create patch cords or for use in a Modular Plug Terminated Link (MPTL) where horizontal cable is terminated on one end to a field-termination RJ-45 and plugged directly into a device, eliminating the outlet and patch cord at the end device.

In addition to individual link insertion loss and length results, a LinkWare Live report includes plenty of other useful information, including the date and time of the test, the test limit selected based on the application and the cable type. And there’s one other bit of information that as an owner and operator you shouldn’t overlook – the TRC verification results. While you may be focused on the individual link results of your test report, all your links could be suspect if the TRCs fail.

Lately it seems that there is a lot of attention surrounding digital lighting and the ability to power and control LED lights over the network infrastructure using Ethernet-based technologies like TCP/IP and PoE. While the benefits of LED lighting are becoming well known – energy efficiency, reduced installation and maintenance costs, and integration with IoT – there’s yet another benefit looming on the horizon.
