  • Publication number: 20220190924
    Abstract: A first optical transceiver outputs a first optical signal while switching the wavelength of the first optical signal to an optical fiber that acts as a medium for carrying single-fiber bi-directional communication between the first optical transceiver and an opposing second optical transceiver. When the wavelength of the first optical signal is switched to a receivable wavelength, the second optical transceiver identifies the wavelength of the received first optical signal, and outputs the second optical signal having a wavelength determined on the basis of the identification result to the optical fiber. When the first optical transceiver receives the second optical signal from the optical fiber, the first optical transceiver stops switching the wavelength of the first optical signal.
