Optical fiber quality analysis method and device, electronic equipment and storage medium

Abstract

The invention provides an optical fiber quality analysis method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring event data and historical fault maintenance data of the optical fiber; inputting the event data and the historical fault maintenance data into a machine learning model to obtain quality scoring information and fault early warninginformation of the optical fiber, the fault early warning information being at least used for indicating a fault position of the optical fiber, and wherein the quality scoring information is used forproviding a reference basis for optical fiber maintenance or not.

Description

technical field [0001] The invention relates to the technical field of optical cable quality analysis, in particular to an optical fiber quality analysis method, device, electronic equipment and storage medium. Background technique [0002] OTDR (Optical Time Domain Reflectometer, Optical Time Domain Reflectometer) is an optical time domain reflectometer, which transmits optical pulses into the optical fiber, uses Rayleigh scattering and Fresnel reflection, and receives the returned curve information at the OTDR port to link status to monitor. When the light pulse is transmitted in the fiber, it will be scattered and reflected due to the nature of the fiber itself, connectors, splices, bending or other similar events. OTDR is widely used in the optical cable maintenance industry. Maintenance personnel analyze the quality of optical fiber by collecting OTDR test curves. [0003] The usual analysis method is to test the spare fiber through OTDR, collect the test curve, impor...

Problems solved by technology

[0004] In recent years, some manufacturers have developed supporting OTDR management software, which can replace part of the manual analysis through the fixed algorithm of the software, but usually the software can only analyze the curves collected by the OTDR equipment produced by the manufacturer itself, and cannot be used in the market.

[0005] It can be seen from the above that the current optical cable quality analysis method mainly relies on manual or single software formula analysis, which has low efficiency and low accuracy, and cannot analyze the development trend of optical cable quality and predict the future failure probability of optical cable
