A method for precise location of optical cable faults

Abstract

A method for accurately locating an optical cable fault, which relates to the technical field of power optical fiber communication detection, solves the problem that the existing method can only obtain the optical fiber length from the measurement point to the fault point, but cannot obtain the actual geographical location of the fault point, and leads to extended maintenance. When a fault is detected in the optical cable, obtain the fiber length information from the OTDR to the fault point; calculate the average value of the distance measured by multiple OTDRs and use it as the actual distance from the fault point to the measurement point, and store the information of the optical cable splice box in the GIS database; Establish a linear reference system for specific optical cable lines; place relevant marker points in the established linear reference system; convert the optical fiber distance from the cable fault point to the measurement point into the distance of the actual optical cable and convert it into a point event in the linear reference system , and displayed on the GIS map. The method can quickly and accurately find the specific geographical location of the fault point of the optical cable, shorten the fault maintenance time, improve the fault handling efficiency, and reduce the loss caused by the communication fault.
