Qual é a maneira correta de testar um MPTL?
You have just received a job specification that includes Modular Plug Terminated Links (MPTLs), with the requirement that all links, including the MPTL, be certified to TIA or ISO standards. This means the customer or manufacturer will look for test reports with “MPTL” as the test limit.

Garantia e testes certificação andam lado a lado em termos de ROI
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.”

O que é perda de retorno?
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).

Melhores métodos de identificação e rastreamento de cabos
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.
