Optical path backup method and device

Abstract

The invention discloses an optical path backup method and device, wherein the method comprises: setting up a main optical path and a standby optical path, connecting the main optical path or the standby optical path to a wavelength division multiplexing module through a switch of an optical path switching module to perform system backup; initialization; Abnormal threshold and optical path switching mode parameters, and determine the optical path switching mode according to the optical path switching mode parameters; the monitoring module collects and monitors the optical power value of the optical path in use, and the optical path in use is the main optical path connected to the wavelength division multiplexing module through a switch. or standby optical path; the monitoring module compares the optical power value of the optical path in use with the abnormal threshold, determines the optical power value status according to the comparison result, and then selects the main optical path or the standby optical path as the link channel for system data transmission according to the optical power value status . By using the aforementioned method, the backup and seamless switching of optical paths can be realized while saving optical fiber resources, which greatly improves the reliability of the 5G network transmission access network, saves optical fiber resources, and reduces construction costs.
