A method and device for detecting the performance of an optical fiber cable

Abstract

The invention discloses a method and device for detecting the performance of an optical fiber cable. The method is that the performance detecting device for an optical fiber cable calculates the nominal optical power of the corresponding optical fiber cable according to the nominal optical power and attenuation parameters of the optical amplifier board corresponding to each section of the optical fiber cable ; and compare the actual optical power of each section of optical fiber cable obtained from the network management server with the nominal optical power of the corresponding optical fiber cable respectively, and use the optical fiber cable whose comparison result is not within the preset normal attenuation value range as Optical fiber cables with performance hazards; output the detection results of all optical fiber cables with performance hazards. By adopting the technical solution of the present invention, through the optical fiber cable performance detection device, the identification of the optical fiber cable with potential performance hazards is determined, and no manual calculation is required to determine the optical fiber cables with potential performance hazards, thereby effectively improving the performance detection efficiency of optical fiber cables and greatly reducing the cost of performance detection. Improved performance detection accuracy.

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...
