ABSTRACT:
In a wavelength-tuning and clock-synchronous system in an optical communication network, a reference office transmits a reference signal via a single transmission line. Data of a reference wavelength and data of a reference clock are superposed in the reference signal. A transmitter office supplies an optical signal whose wavelength is tuned based on the reference wavelength extracted from the reference signal and whose clock is synchronized based on the reference clock extracted from the reference signal. A receiver office receives wavelength-division-multiplexed signals as time-division-demultiplexed parallel data by using a clock extracted from the reference signal.
