Abstract: Embodiments of this application provide an optical component, an optical switching fully-interconnected system, and a communication system, to reduce a backplane loss of an optical signal between the optical component and a switching node. The optical component specifically includes: a service processing module, an optical-to-electrical conversion module, a multiplexer, an optical switching switch, an optical receiving module, and an optical connector. When the optical component serves as a transmitting end, a first electrical signal generated by the service processing module is converted by the optical-to-electrical conversion module to generate a first optical signal, and the first optical signal is multiplexed by using the multiplexer and is output to a next-hop optical component through the optical switching switch and the optical connector.

Abstract: A clock synchronization method and a communication apparatus are provided. The method includes: multiplexing a local analog clock signal and a first data signal to obtain a first multiplexed signal; sending the first multiplexed signal to a first apparatus; receiving a second multiplexed signal from the first apparatus; demultiplexing the second multiplexed signal to obtain a second data signal and a first analog clock signal, where the first analog clock signal corresponds to the local analog clock signal after it has gone through a transmission delay; obtaining a first signal based on the first analog clock signal, where the first signal is a delay compensation amount or a second analog clock signal, and the second analog clock signal is obtained by applying delay compensation to the local analog clock signal; and processing data based on the first signal to obtain the first data signal, to which delay compensation has been applied.
