摘要： An optical add/drop multiplexer branching unit is provided, where the optical add/drop multiplexer branching unit includes: a trunk input end, a branch input end, a trunk output end, a branch output end, an optical add/drop multiplexer, a first coupler, a first detection circuit, and a control circuit, where the optical add/drop multiplexer includes an optical switch. A detection circuit detects whether a fault occurs in a trunk, and in a case in which a fault occurs in the trunk, a working mode is switched from a first working mode to a second working mode, to implement automatic redundancy on the trunk and ensure normal communication on a branch. According to the foregoing solution, a redundancy function is implemented without integrating an amplifier. Manual intervention is unnecessary, and a redundancy response speed is fast, thereby improving a redundancy effect, and significantly reducing an economic loss caused by system service transmission interruption. A used optical switch component is small in size, has a low requirement on structure space, and is of low complexity in structural design. Therefore, structural complexity is reduced, so as to reduce costs and improve reliability.

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, and enhancing the disaster recovery capability of the optical communication system. Furthermore, the solutions in the embodiments of the present invention do not introduce extra energy into a transmission link, thereby introducing no spontaneous emission noise and ensuring system performance.

摘要： The present invention relates to communications technologies, and discloses a method for monitoring the state of a fiber line, a repeater, and a submarine cable system. The repeater includes a first optical amplifier, a second optical amplifier, a first gating unit, a second gating unit, a first coupler, a second coupler, a third coupler, and a fourth coupler. The first coupler, the fourth coupler, and the first gating unit form an in-to-in loopback path between the input end of the first OA and the input end of the second OA; and the second coupler, the third coupler, and the second gating unit form an out-to-out loopback path between the output end of the first OA and the output end of the second OA. With the repeaters of such a structure being applied, the monitoring device may monitor both the state of the uplink fiber and the state of the downlink fiber of the submarine cable on a single end of the submarine cable system.
