While certifying a cable plant, an installer repeatedly experiences complex near-end crosstalk (NEXT) failures on multiple links. Overwhelmed by issues with the cabling plant and the customer demanding answers, she needs expert help to troubleshoot...
Return loss is the ratio of signal power injected from a source compared to the amount that is returned or reflected back toward the source. It is a critical performance parameter in both copper twisted pair and fiber optic cabling systems, because...
Every time you complete the installation of a structured cabling system, you can choose whether to certify it. All links in the system should be tested in some way to make sure that they’re connected properly, but is it necessary to measure and...
Staying on top of the critical technological developments in network cabling infrastructure helps you — and your company — stay current and competitive. One way to do that is to participate in an accredited training and certification program, like...
As the leading provider of instructor-led training for fiber optic technicians, Light Brigade was an obvious choice to give us feedback during the development of the FiberLert™ Live Fiber Detector. Recently, Sean Kelly, RCDD, CFHP, and Technical...
Although contractors spend a great deal of time and care designing and labeling cable installations, everyone who works on cabling runs into instances where they’re not sure where a cable goes. Perhaps the cable wasn’t labeled correctly when it was...
It seems no matter where you live – the plains, the east coast, the UK or even our typically-cool Pacific northwest – the news is all about record-setting heat. Worse, a lot of our favorite coping methods are unavailable – gas makes it too costly to...
Today’s high-tech data centers form the digital heart of communication and commerce in our world. But every industry has its “remember when” stories, and there's no better time than now to tell them.
It’s been a few years since the Institute of Electrical and Electronics Engineers (IEEE) introduced the IEEE 802.3cg-2019 single-pair Ethernet (SPE) 10 Mb/s standards . There’s been a lot of industry activity and collaboration surrounding the...
There are plenty of hazards to watch for when working on commercial and industrial networks. Fiber optic cable can seem safe; it doesn’t carry an electrical charge, and it’s not a heat source. More often it’s a lack of understanding of the real...
