Abstract: A communication system, a transmitter, and a communication method. The communication system includes M transmitters, N receivers, and an optical switch network. Both N and M are positive integers greater than 1. The optical switch network includes one or more optical switches. A plurality of optical paths are configured in the optical switch network. When the transmitter communicates with the receiver, the transmitter can determine, from the plurality of optical paths, a target optical path from a source communication node to a destination communication node. After the optical switch network receives a target optical signal sent by the transmitter, the optical switch directly sends the target optical signal to the receiver based on the target optical path.
