Claim 9:
10. The non-transitory computer readable medium according to claim 8, 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.
