Electric power communication optical cable fault monitoring device

The invention relates to the technical field of optical cable fault monitoring, in particular to an electric power communication optical cable fault monitoring device which comprises a first shell, upper rollers are rotationally connected to the left side and the right side of the upper portion of the first shell, and the rear portion of the upper roller on the left side is fixedly connected to the front side driving end of a servo motor. The servo motor is fixedly connected to the rear side of the first shell, the upper roller is arranged on the upper portion of the optical cable, and a power source assembly is arranged on the upper portion of the first shell. The servo motor drives the upper roller to rotate on the optical cable, the detection range is enlarged, meanwhile, the labor cost is reduced, and the device is firm in connection and not prone to falling off; meanwhile, the optical cable can be knocked in a reciprocating mode in the moving process, the optical cable can be detected in cooperation with
