保証と認証試験が連動してROIを実現
One could argue that certification testing of an installed structured cabling plant is optional and time consuming.

リターンロスとは？
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).
