摘要： A method, an optical add-drop multiplexer branching unit, and a system for disaster recovery of an optical communication system are provided. The method for disaster recovery of an optical communication system using an optical add-drop multiplexer unit (OADM) includes: detecting a transmission link fault in an optical communication system; and when a transmission link fault is detected, switching the state of a link where the transmission link fault occurs from pass-through to loopback, so that an optical signal input from a non-faulty end of the link is looped back to the end for outputting. In this way, when a transmission link fault occurs in an optical communication system, the power level of a link where the transmission link fault occurs can be maintained by using the solutions in the embodiments of the present invention, thereby keeping transmission performance stable.
