AI Technical Summary

Technical Problem

Existing optical communication links fail to respond promptly to disaster recovery and failover, resulting in insufficient service continuity. Traditional methods cannot monitor link performance in real time, and failover triggering timing is inaccurate and cannot be adaptively adjusted.

Method used

By analyzing the transmission performance parameters of the optical fiber link, EDFA amplifier units are deployed to monitor the status of the primary optical fiber link in real time. The control unit switches to the backup optical fiber under preset conditions and adjusts the EDFA amplifier status according to the optical path loss and wavelength after the switch to adapt to the service optical path.

Benefits of technology

It enables rapid and stable disaster recovery switching in the event of optical communication link failure, improves service continuity assurance, and reduces interruption time and power surges during switching.

Abstract

The application discloses an optical communication disaster recovery backup method and system based on an EDFA amplifier, and relates to the technical field of optical communication. The method comprises the following steps: analyzing the transmission performance parameters of an optical fiber link, and deploying an EDFA amplifier unit based on the transmission performance characteristics; monitoring the state parameters of the main optical fiber link in real time; when the state parameters meet the preset switching conditions, making a switching decision by a control unit, controlling the optical switch module inside the EDFA amplifier unit, and switching the service optical path from the main optical fiber to the standby optical fiber; and adjusting the working state of at least one EDFA amplifier related to the standby optical fiber path according to the optical path loss and wavelength after switching, and adapting the service optical path after switching. The technical problem that the disaster recovery switching response is not timely when the optical communication link fails in the prior art, resulting in insufficient service continuity guarantee, is solved, and the technical effect that the switching is triggered quickly and stable disaster recovery switching is completed when the link state is abnormal is achieved.
