In a data communication system, a circuit for regenerating an optical signal that is deteriorated during the course of transmission has an optical clock generator for generating an optical clock signal whose frequency is equal to the bit rate of an optical signal input to a preselected port thereof. The clock generator outputs the clock signal via the same port as the optical signal is input. The circuit is capable of regenerating the optical signal while efficiently separating the optical signal and clock signal respectively input to and output from the clock generator. |
