Abstract:
1. An optical multiplex communication system, comprising: an optical code division channel section for encoding an optical pulse signal of an optical code division channel by an encoder and generating an encoded optical pulse signal, and an optical wavelength division channel section for generating a wavelength division optical pulse signal, both being provided at a transmission side in parallel; and an optical code division multiplex signal extraction section having a decoder to generate a decoded optical code division signal, and an optical wavelength division multiplex signal extraction section having a wavelength demultiplexer for extracting optical pulse signal components of a plurality of optical wavelength division channels, both being provided at a receive side in parallel, wherein said optical wavelength division channel section has an optical delay unit for each of said plurality of optical wavelength division channels, so as to provide, to said optical pulse, time delay required for not matching a position of an optical pulse constituting said wavelength division optical pulse signal on a time base, and a position of a chip pulse constituting said encoded optical pulse signal which has a same wavelength as said optical pulse on the time base.
