ABSTRACT:
Disclosed is a method of and an apparatus for conducting communications using an optical communication system that includes a plurality of light transmitters and a plurality of light receivers mutually connected to the plurality of light transmitters. The communication method includes detecting, from a predetermined wavelength range, first and second wavelengths in one of the light transmitters, which wavelengths are different from each other and which have not been used by other light transmitters; conducting communications between one of the light transmitters and one of the light receivers using light having the first wavelength; and conducting communications between the light transmitter and the light receiver using light having the second wavelength when the quality of the communications using the light having the first wavelength deteriorates. Also disclosed is a method of and an apparatus for conducting communications using an optical communication system that includes a plurality of mutually connected light transceivers. This communication method includes conducting communications between those light transceivers which are a selected pair of light transceivers using light having a set wavelength; detecting interference in the communications between the selected pair of light transceivers and interference in those light transceivers other than the selected pair; and shifting the set wavelength to avoid the interference when interference is detected.
