Abstract: An optical transmission device is disclosed, comprising a tributary board, an active line board, a protection line board, an optical amplifier board, an electric cross unit, and a first multiplexer/demultiplexer board. The first three boards are electrically connected to the electric cross unit. The second to fourth boards are optically connected to the first multiplexer/demultiplexer board. A quantity of protection line boards is less than that of active line boards. A first port of the tributary board and a second port of the optical amplifier board are respectively configured to transmit client service data and an optical signal carrying the client service data. When a preset condition is met, the electric cross unit copies or schedules, to the protection line board, client service data to be processed by the active line board, and the first multiplexer/demultiplexer board performs multiplexing and demultiplexing together with the protection line board.

Abstract: Embodiments of this disclosure disclose an optical backplane switchover method and an optical communication device. Each optical signal processing board in the optical communication device is connected to at least two optical backplanes, where a first optical backplane is a currently working optical backplane, and a second optical backplane is a spare optical backplane. If a first optical link on the first optical backplane is faulty, a selector switch on the optical signal processing board is controlled to perform switching, to disconnect the optical signal processing board from the first optical backplane and connect the optical signal processing board to the second optical backplane. In other words, when the optical backplane is faulty, switchover may be performed from the faulty optical backplane to the spare optical backplane. In this way, normal transmission of an optical signal is ensured without replacing the entire optical communication device, thereby simplifying maintenance.
