Abstract
The application provides an optical communication system applied to the field of optical communication. In the optical communication system, N transmitters are used for transmitting N first optical signals to an optical signal exchange device. The optical signal exchange device is used for dividing each first optical signal into X band signals of different bands, so as to obtain X*N band signals. Each band signal in the X band signals carries the same digital telecommunication signal. X is an integer greater than 1 and less than or equal to M. The optical signal exchange device is also used for obtaining M second optical signals according to the X*N band signals. M receivers are used for receiving the M second optical signals from the optical signal exchange device. In the application, by dividing the first optical signal into X band signals, the optical signal exchange device can directly transmit different band signals to different receivers without photoelectric conversion, so as to reduce the communication delay between the transmitter and the receiver.
