Abstract

An embodiment of the invention provides an optical fiber monitoring method and system, equipment and a storage medium. In the optical fiber monitoring method of the invention, an OTDR continuously injects an optical pulse into an optical fiber and receives backscattered light returned by the optical fiber during a monitoring period, the OTDR or network management equipment performs sliding window processing on an electric signal sequence corresponding to the backscattered light, and monitors the quality of the optical fiber during the period corresponding to a current sliding window according to the electric signal sliding into the sliding window every time. The optical fiber monitoring method is used for monitoring the quality of the optical fiber through the sliding window, and the monitoring flexibility can be improved.

Description

technical field [0001] The present application relates to the technical field of optical communication, in particular to an optical fiber monitoring method, device, system and storage medium. Background technique [0002] Optical fiber communication is a communication method in which light waves are used as information carriers and optical fibers are used as transmission media. Fiber quality has a crucial impact on signal transmission quality. In an existing optical communication system, an optical time domain reflectometer (Optical Time Domain Reflectometer, OTDR) is often used to detect the quality of an optical fiber. However, the existing OTDR has poor flexibility for optical fiber quality monitoring. Contents of the invention [0003] Aspects of the present application provide an optical fiber monitoring method, device, system and storage medium to improve the flexibility of optical fiber monitoring. [0004] An embodiment of the present application provides an opt...
