Today, fiber-optic cable in data centers and information centers can be found everywhere, almost the backbone of the network are dominated by fiber. When we are happy for the network speed increase, we have to face the accompanying fiber optic failure of all kinds.

Optical Time-Domain Reflectometers (OTDRs) are essential tools for measuring the performance and integrity of optical fiber networks. OTDRs are used to diagnose faults, measure attenuation, and verify the integrity of fiber optic links. However, with so many OTDRs on the market, it can be challengin
