Abstract

The invention discloses a method and a system for roll-call testing of optical fibers. The method includes: an RTU (remote terminal unit) performs OTDR (optical time-domain reflectometry) testing for an LMC (land mobile channel) designated optical fiber under control of an LMC and sends an OTDR curve obtained by OTDR testing to the LMC; the LMC receives the OTDR curve to perform fault analysis according to the OTDR curve; and the LMC stores fault analysis results. The method and the system are capable of performing fault testing for the designated optical fibers.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and system for roll call testing of optical fibers. Background technique [0002] With the development of the modern power communication industry, optical cables are widely used in communication transmission. [0003] Although the existing communication transmission network has functions such as network management and protection switching, it generally does not support the detection of optical cable characteristics. [0004] When the optical cable in the communication transmission network fails, it is impossible to determine the location of the failure, so that the faulty optical cable cannot be quickly repaired. Contents of the invention [0005] In view of this, the technical problem to be solved by the present invention is to provide a method and system for roll call testing of optical fibers, which can perform fault testing on specified optical fibers. [0006] For ...
