Abstract

The invention discloses an optical cable fault detection method and device. The method comprises the following steps: sending a detection signal with a preset wavelength to a to-be-detected target optical cable; receiving a feedback signal fed back by the detection signal, and determining the power of the feedback signal; when the power is less than the power threshold, determining that the target optical cable has a fault; and under the condition that the target optical cable has a fault, determining the fault position of the target optical cable according to the transmission parameter of the detection signal. The technical problem that optical cable fault detection is not comprehensive and accurate enough in the prior art is solved.

Description

technical field [0001] The invention relates to the field of optical cable detection, in particular to an optical cable fault detection method and device. Background technique [0002] At present, power special optical cables have been widely used in the world, especially optical fiber composite overhead ground wire (OPGW) and all-dielectric self-supporting optical cable (ADSS). The power special optical cable is less likely to be damaged by external forces and has high reliability. It can be laid directly on the power line relying on the line corridor of the power system itself, without the need to open another trench or special erection. It is economical and free from electromagnetic interference, and has abundant optical fiber resources. , Anti-chemical corrosion, avoiding conflicts with the outside world in terms of frequency resources, routing coordination, electromagnetic compatibility, etc., and has great active flexibility. OPGW has dual functions of power overhead ...
