Patent ID: 10536237

Abstract:
An optical transceiver includes: a wavelength-tunable transmitter transmitting an optical transmission signal; a wavelength-tunable receiver receiving an optical reception signal; a wavelength table storing a plurality of wavelengths; an input terminal inputs a wavelength selection signal; and a control unit that identifies one of the optical transmission signal and the optical reception signal as a target based on the wavelength selection signal, selects the wavelength from the wavelength table based on the wavelength selection signal, performs transmission wavelength control in which the selected wavelength is set in the wavelength-tunable transmitter as a wavelength of the optical transmission signal in the case that the optical transmission signal is identified as the target, and performs reception wavelength control in which the selected wavelength is set in the wavelength-tunable receiver as a wavelength of the optical reception signal in the case that the optical reception signal is identified as the target.
