The fault distance from the optical cable to the test equipment is given, and the fault point is difficult to find and eliminate quickly in the visual environment of the channel.
2. In the prior art, optical cable fault location is also performed through communication data chain analysis. The detection method has the problems that a loop of a communication link cannot be formed after the optical cable fails, namely, when communication detection is carried out, a fault line can be found, and when the optical cable cannot complete information transmission, the fault end can receive test data of the detection end and can return a test requirement to the test end.
3. The method comprises the steps of conducting fault elimination on an optical cable in a channel, not only finding a fault, but also only measuring the distance from a fault point to a test point through OTDR, and knowing a specific geographical position, particularly converting the test distance into a path distance of the optical cable in the underground channel, converting the path distance into an actual path according to the path distance, and finally determining the position of the cable fault point through the path.
