Maybe you’ve been hearing some buzz recently surrounding single-pair Ethernet and a couple of new standards in development to support 10 Mb/s Ethernet. If you’re thinking that 10 Mb/s seems like old school, you’re probably not alone. After all, 10BASE-T has been around since the 1990s and is rarely even used as a signaling rate in today’s LANs. But this latest 10 Mb/s application is something different, and it has countless opportunities for a wide range of low-speed, low-bandwidth IoT devices – all over a single pair.

When it comes to Tier 2 fiber testing, there are many smart people in our industry who can read an OTDR trace and pinpoint the type and location of a fault within the cable. And for those who might not be proficient in reading a trace, Fluke Networks’ OptiFiber Pro OTDR features advanced logic that automatically interprets the trace to provide a detailed and graphical map of events that includes the location of connectors, splices and anomalies.

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.

When it comes to testing a cabling installation, there are essentially three choices--verification, qualification and certification.
While some features overlap between test tools as you move up the hierarchical ladder from verification to certification, each type of testing answers one of the following questions to help you make the right choice.
