WAVELENGTH TUNEABLE OPTICAL TRANSCEIVER AND METHOD FOR ALIGNING WAVELENGTH OF WAVELENGTH TUNABLE OPTICAL TRANSCEIVER USING THE DIGITAL FRAMER OVERHEAD

摘要

The present invention relates to a wavelength-tunable optical transmitter/receiver capable of transmitting the wavelength allocated to an own channel only to a counter terminal by being connected to an optical multiplexer and automatically finding the wavelength to be outputted. The wavelength-tunable optical transmitter/receiver includes: a modulation digital framer which modulates an input signal from the user of an own terminal and delivers the signal to a laser driver; the laser driver which amplifies received current to drive a laser; a wavelength tuning driving unit which drives a wavelength tuning unit; the wavelength tuning unit which receives control current from the wavelength tuning driving unit and controls the laser to output a certain wavelength corresponding to the control current; a controller which controls the wavelength tuning driving unit and digital framer; a receiving unit which converts an optical signal from the user of a counter terminal into an electric signal; and a demodulation digital framer which removes digital frames from the electric signal received from the receiving unit and extracts and outputs the input signal from the user of the counter terminal only.
