The application discloses a kind of computing power node optical switching equipment and optical switching system, belong to optical switching field, considering that optical communication is naturally with the characteristics of larger bandwidth, and by first optical splitter, the optical signal multiplexing of computing power node can be multiple to optical switch, optical switch can flexibly realize the signal routing between each optical port, therefore, first optical splitter in the application includes at least one first end and multiple second ends, the first end is connected with a corresponding computing power node in server, and the second end is connected with optical switch through optical backplane;And optical switch can route the received optical signal to the corresponding target optical port under the control of control module;By controlling optical switch, the optical communication between different computing power node combinations performing the same computing task can be flexibly realized, and has larger bandwidth, and complex fiber layout can be avoided through optical backplane.

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.
