One could argue that certification testing of an installed structured cabling plant is optional and time consuming. But if an end user wants a system warranty, “optional” is the last word to describe this crucial step. As Panduit’s product line manager Frank Straka put it, “Certification testing will always be required for warranty, regardless of the number of drops on a project.”

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 it can interfere with the transmitted signal and can contribute to an increase in the measured insertion loss (the amount of power that a that a signal loses as it travels along a cable link).

ケーブル認証がかつてないほど重要である 3 つの理由
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 document the performance of every link?

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 installed. Or maybe it was a technician’s "temporary" addition that has lasted for years. Learn which cable toners, identifiers, network cable testers and probes can help you cut the time you spend figuring out where that cable actually goes.

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 go to the beach or mountains, pools are closed due to lifeguard shortages, and now you can´t even help yourself to an ice-cold Choco Taco.

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 technology since then — so we thought it would be a good time for an update on the status of Single-Pair Ethernet (SPE).
