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.
An optical communication device, comprising a first optical signal processing board, a second optical signal processing board, a first optical backplane, and a second optical backplane, wherein
