Intelligent optical cable line fault positioning method

The invention provides an optical cable line fault intelligent positioning method. An optical time domain reflectometer (OTDR) module, an optical power meter module, a power supply module, a main control module, a display module, a storage module, a communication module, an optical splitter, an optical switch and an optical amplifier are included. The detection unit comprises an optical switch, an OTDR and an optical amplifier, the optical switch with the specification of 1 * 32 is selected to achieve the effect that one set of equipment detects multiple optical fibers, the working optical fibers and the standby optical fibers are detected in a polling mode of the optical power meter module, and when it is found that the optical power value of one optical fiber is lower than a preset value, the OTDR is called in time to measure the corresponding optical fiber fracture point, and the optical power value is accurately measured. By applying the technical scheme, the stable operation and the repair of the communi
