Abstract

The invention discloses an optical cable anomaly detection method and device. The method comprises the following steps: sending a detection signal with a preset wavelength to a to-be-detected target optical cable; receiving a feedback signal fed back by the detection signal, and determining a power curve of the feedback signal; performing wavelet transformation on the power curve to obtain an attenuation curve; and according to the attenuation curve, determining the abnormal event of the target optical cable and the position thereof. According to the invention, the technical problem of low accuracy of optical cable fault detection in the prior art is solved.

Description

technical field [0001] The invention relates to the field of optical cable detection, in particular to an optical cable abnormality detection method and device. 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] The main detection purpose of optical fiber monitoring is to detect the singular point or fault point position in the optical fiber...
