PURPOSE:To independently execute a rooting processing in a receiving node regardless of communications information and to compose a light self routing channel with a high flexibility by allocating a wave length pattern which is a specific combination among plural wavelengths for respective receiving nodes. CONSTITUTION:As an address to indicate the address of a receiving node 12 to which the communications information is delivered, the wave length pattern composed of plural or single wave length is used, and the communications information is simultaneously light-modulated by plural or single wave length to compose the save length pattern. Thus, the routing processing in the receiving node 12 can be realized by a passive light signal processing to use a wave length filter 103 and a light detector 104, it can be independently executed regardless of a communicating speed, and the light self routing channel without any restriction to the communication speed and with an excellently high flexibility can be composed. |
