The Poet’s Guide to the Physics of Twisted Pair Cabling
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”.

6912-Fiber Cable: Now That’s Testing!
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.

Versiv Keeps on Truckin’
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.

Bandwidth and Data Rates
The terms bandwidth and data rates are often used interchangeably, but they are in fact very different if you work in the cabling world.

Cable Tracing – Up to 600 V?
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.

Three New Innovative Products and Maybe a Future One?
If you dropped by the Fluke Networks booth at the Fall BICSI Exhibition on Las Vegas this week, you had a chance to see three winners of the Cabling Installation and Maintenance Magazine’s Innovator’s Awards, and a possible candidate for a future award.

Different Plugs, Same Test
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.

TRC Results: Why You the Owner Should Care
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.

Lighting the Way for Visible Light Communications
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.
