Abstract

The invention discloses an optical fiber operation state monitoring method. The method comprises the following steps: acquiring a scattered light signal of test light of a predetermined pulse emitted at a sampling point, wherein the test light is propagated and scattered back through a target optical fiber; acquiring the propagation time required for reflecting the scattered light signal propagated by the target optical fiber to the sampling point; determining the distance between the sampling point and the tail end of the target optical fiber according to the required propagation time; obtaining an optical power value of the scattered light signal and an initial power value of the test light, and obtaining a relative power value according to the optical power value and the initial power value; obtaining a target curve graph according to the relative power value and the distance; and matching the first change trend of the target curve graph with the second change trend of a preset reference curve graph, and obtaining the operation state of the target optical fiber according to a matching result. The technical problems of high labor cost and low efficiency caused by judging whether the optical cable has the fault or not based on manual detection of the OTDR curve in the related technology are solved.

Description

technical field [0001] The present application relates to the field of optical fiber monitoring, in particular, to a method for monitoring the operating state of an optical fiber. Background technique [0002] With the rapid development of optical fiber networks, the complexity of the network is increasing day by day, and the management and maintenance of optical fiber physical networks are becoming increasingly heavy. Timely detection of fiber optic network failures and ensuring the security and stability of the fiber optic physical network are the current focus of network maintenance. Therefore, there is an urgent need to establish a fiber optic monitoring system that organically combines fiber optic monitoring, warning, fault analysis, positioning, and line maintenance to provide guarantees for the safe and efficient operation of fiber optic networks. [0003] In the related art, the condition of the optical fiber is detected by monitoring the condition of the transmissi...
