Optical cable performance detection method and device

Abstract

The invention discloses an optical cable performance detection method and a device. The method comprises steps that an optical fiber performance detection device calculates the normal optical power of the corresponding optical fiber according to an optical amplification plate normal optical power and attenuation parameters corresponding to each optical fiber, compares the actual optical power of each optical fiber at this moment obtained from a webmaster server with the normal optical power of the corresponding optical fiber, regards the optical fiber whose comparison result is not in the preset normal attenuation value range as an optical fiber with a hidden performance danger and outputs a detection results of optical fibers with the hidden performance dangers. In this way, via the optical fiber performance detection device, identifications of the optical fiber with the hidden performance dangers are determined with no need for manual calculation and determination on the optical fibers with the hidden performance dangers, thereby effectively increasing performance detection efficiency of the optical fibers, greatly reducing cost of performance detection and increasing accuracy rate of the performance detection.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting the performance of an optical fiber cable. Background technique [0002] In the communication system, the optical signal quality transmitted in the optical fiber cable must meet the optical signal quality required by the transmission equipment connected at both ends of the optical fiber cable, and the primary parameter to measure the optical signal quality is the optical power. Therefore, optical fiber The optical power of the cable is the most important parameter to characterize the performance of the transmission trunk fiber optic cable. [0003] At present, in the process of detecting the performance of optical fiber cables, preset alarm thresholds are usually used. When it is detected that the optical power of any section of optical fiber cable reaches the above preset alarm threshold, the network management system will send out an ala...
