Optical cable fault accurate location method

Abstract

The invention relates to an optical cable fault accurate location method and relates to the technical field of power optical cable communication detection, which solves the problem that the existing method only obtains the fiber length of a measurement point from a fault point but cannot obtain the actual geographical position of the fault point, and leads to extension of maintenance. When monitoring that the optical cable breaks down, the fiber length information of the OTDR from the fault point is obtained; the average value of the distance measured by OTDR for multiple times is calculated and used as the actual distance of the fault point from the measurement point to store the information of an optical cable connector box into a GIS database; a linear reference system for a specific optical cable line is established; the relevant marker point is placed in the established linear reference system; the optical fiber distance of the optical cable fault point from the measurement pointis converted into the distance of an actual optical cable, which is converted into a point event in the linear reference system and displayed on the GIS map. The method can quickly and accurately findthe specific geographical location of the fault point of the optical cable, shorten the fault maintenance time, improve the fault processing efficiency, and reduce the loss caused by the communication fault.
