1. An optical transceiver comprising:

  • a wavelength-tunable transmitter configured to transmit an optical transmission signal;

    a wavelength-tunable receiver configured to receive an optical reception signal;

    an input terminal configured to input a wavelength selection signal as one or more of control pulses;

    a wavelength table configured to store a plurality of combinations of a transmission wavelength and a reception wavelength, each of the plurality of combinations being correlated with a respective number of the control pulses; and

    a controller configured to select one combination of the transmission wavelength and the reception wavelength, which corresponds to the number of the control pulses as the wavelength selection signal, from the wavelength table, and performs transmission wavelength control for setting the selected transmission wavelength in the wavelength-tunable transmitter as a wavelength of the optical transmission signal and reception wavelength control for setting the selected reception wavelength in the wavelength-tunable receiver as a wavelength of the optical reception signal.
