Troubleshooting Fiber on the Cheap
If you troubleshoot fiber on a regular basis, you probably have an array of tools to help you do the job, including an Optical Time Domain Reflectometer. But we often get questions from customers who don’t troubleshoot fiber enough to justify such an expensive tool.

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”.

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.
