[0002] An optical time domain reflector (OTDR) is an instrument used to test the performance of optical fibers. It is mainly used to evaluate problems such as uniformity, defects, breaks, and splice coupling in optical fibers. By injecting light pulses into the optical fiber and analyzing the reflected light signals, the performance parameters of the optical fiber can be obtained. OTD devices have a wide range of applications in the maintenance and monitoring of optical fiber communication networks.
