Claim 0:
1. A long-distance optical fiber detecting method, comprising:
in response to a detection request of a target node on a to-be-detected optical fiber, determining a first sampling sequence and a second sampling sequence that are formed by respectively propagating, on the to-be-detected optical fiber, a first optical signal and a second optical signal respectively sent from each end of the to-be-detected optical fiber by an OTDR;
determining a total length of the to-be-detected optical fiber;
generating a detection result according to the first sampling sequence, the second sampling sequence, and the total length; and
sending the detection result to the target node,
wherein the determining the total length of the to-be-detected optical fiber comprises:
determining a sending time of a third optical signal recorded by a sending node; the third optical signal being used for measuring the to-be-detected optical fiber;
determining a receiving time of the third optical signal recorded by a receiving node;
determining a propagation duration of the third optical signal on the to-be-detected optical fiber according to the sending time and the receiving time; and
determining the total length of the to-be-detected optical fiber according to the propagation duration.
