Abstract:
1. A method for locating a fault of a submarine cable, the method comprising: receiving, by a Repeater (RPT), on a span to which a location of the fault belongs, an executing location detection command sent by a Submarine Line Terminal Equipment (SLTE); triggering generation of a probe light pulse according to the received executing location detection command; transmitting the probe light pulse to the location of the fault along a sending direction of the SLTE; recording start time T detecting the probe light pulse reflected from the location of the fault, and obtaining time T sending the time T generating, by a pump laser in the RPT, pump light according to the received executing location detection command, and inputting the pump light into a Erbium-Doped Optical Fiber Amplifier (EDFA) in the RPT; setting up, by an optical switch in the RPT and according to control of a controller in the RPT, a connection between the EDFA and the location of the fault at the time T wherein detecting the probe light pulse reflected from the location of the fault and obtaining the time T setting up, by the optical switch in the RPT, a connection between a probe in the RPT and the location of the fault at the time T
