Claim 2:
3. The method of claim 1, wherein after generating the detection result according to the first sampling sequence, the second sampling sequence and the total length, the method further comprises:
in a case where the detection result does not meet a preset condition, determining a third sampling sequence and a fourth sampling sequence that are formed by respectively propagating, on the to-be-detected optical fiber, a fourth optical signal and a fifth optical signal sent from each end of the to-be-detected optical fiber by a third ODTR and a fourth OTDR respectively disposed at each end of the to-be-detected optical fiber, wherein a sum of dynamic ranges of the third optical time-domain reflectometer and the fourth optical time-domain reflectometer is larger than a sum of dynamic ranges of the OTDRs sending the first and second optical signals;
regenerating an update detection result according to the third sampling sequence, the fourth sampling sequence and the total length;
sending the update detection result to the target node.
