Description

technical field [0001] The invention relates to the technical field of electric power communication, in particular to a method and device for locating a fault location of a communication optical cable in a distribution network. Background technique [0002] With the large-scale application of optical fiber communication technology in the power communication network, the scale of optical cables in the power communication network is rapidly expanding, and the distribution of optical cable lines is becoming more and more complicated. Since there is no instrument that can accurately measure the ground position of the fault point of the optical cable, once the optical cable fails (such as fiber break, loose interface, contamination, bending, aging, etc.), it becomes a very difficult task to accurately locate the fault point. [0003] The traditional method of locating the fault point of the optical cable is to first use an Optical Time-Domain Reflectometer (OTDR) to measure the l...
