OTDR, full name: optical time domain reflectometer, is based on the analysis of the measured curve, It’s a machine according to understand the performance about uniformity, defect, fault, joint coupling etc. The performance of several instruments. It according to optical backscatter and Fresnel principle of reverse, when the use of light propagation in optical fiber attenuation of backscatter light to get information, can be used for measuring optical attenuation, splicing loss, fiber optic fault point positioning, and understand the status of loss distribution along the length of optical fiber, etc., is an essential part of fiber optic cable construction, maintenance and monitoring tools.
