  • controlling dispersion added to the optical signal to be larger than a specified amount;

    controlling a delay time of at least one of the first channel and the second channel in the receiver based on a quality of the optical signal monitored in the receiver to suppress the skew between the first channel and the second channel in the receiver; and

    controlling a delay time of at least one of the first channel and the second channel in the transmitter based on a quality of the optical signal monitored in the receiver to suppress the skew between the first channel and the second channel in the transmitter.
