测试 MPTL 时正确方法是什么？
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.

保修和认证测试相结合，实现理想的投资回报
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.”

什么是回波损耗？
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).
