Zusammenfassung:PURPOSE: An optical network device is provided to transceive an optimized optical signal through wavelength locking or wavelength stabilization. CONSTITUTION: A T-TRX(Tunable Optical Transceiver)(312a~312n) transmits an optical signal to an OLT(Optical Line Terminal)(300) through an RN(Remote Node)(350). A photo detector(343a~343n) receives an amplitude modulated optical signal from the RN. The photo detector converts the amplitude modulated optical signal into an electric signal. An optical wavelength controller(311a~311n) controls the wavelength of the optical signal to be a reference wavelength.
