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.
