While the most common causes of failures in twisted pair cabling include installation errors, defects found in poor-quality components (cables, connectors, patch cords, etc.), damage to the installed cable and incorrect tester set up, sometimes technicians want to know specifically WHY a link failed.
Based on which performance parameter failed testing, there are specific possible causes that a technician can consider. Let’s take a closer look.

If you recently attended the BICSI Winter Conference in Orlando, picked up an industry publication or participated in a webinar, you’ve probably been exposed to plenty of information on PoE and its effect on cabling plants. By now, you may even be tired of hearing about heat rise in bundles of cables that are delivering remote power to devices and how this can cause insertion loss, degrade the cable and impact Ethernet transmission.

Insertion loss, or the loss of signal that happens along the length of a fiber optic link, is expressed in dBs and should always be a positive number. But it can be negative (which isn’t a good thing).
Return loss, which measures the amount of light reflected back toward the source, is also expressed in dBs and is always a positive number. A high return loss is a good thing and usually results in low insertion loss.
Reflectance, which also measures reflection and is expressed in dB, is a negative number. High reflectance is not a good thing.
