Abstract: Using the beat signal obtained by detecting two optical channel groups simultaneously, the present invention provides a more precise control of the channel spacing of dense-wavelength-division-multiplexed (DWDM) systems than conventional methods using optical filters. Each channel group consists of at least one optical channel. The polarization dependence of the beat signal is suppressed using a polarization controller or a polarization scrambler. With this invention, the DWDM channel spacing can be made a few 10 GHz or less. This invention further provides a bi-directional optical communication system that can minimize the channel crosstalks caused by various optical reflections slightly shifting counter propagating optical channel frequencies.
