Optical code division multiplexing communication method and system

An optical code division multiplexing communication system comprising:

• an encoder for producing a multi-wavelength optical pulse train from wavelength multiplexing pulse;
• a decoder for decoding the wavelength multiplexing pulse from the multi-wavelength optical pulse train after the multi-wavelength optical pulse train is transmitted through a transmission line using a time-spreading/wavelength-hopping method;
• a delay time difference compensator for compensating delay time differences between individual optical pulses of the multi-wavelength optical pulse train, the delay time differences occurring when the multi-wavelength optical pulse train is transmitted through the transmission line;
• and
• a chromatic dispersion compensator for compensating optical pulse spread in a time direction, which occurs in each of optical pulses of the multi-wavelength optical pulse train when the multi-wavelength optical pulse train is transmitted through the transmission line.

A decoding device comprising:

• a decoder for decoding wavelength multiplexing pulse from a multi-wavelength pulse train transmitted through a transmission line in an optical code division multiplexing communication, in which the multi-wavelength optical pulse train produced from wavelength multiplexing pulse is transmitted through the transmission line using a time-spreading/wavelength-hopping method and the wavelength multiplexing pulse is decoded from the multi-wavelength optical pulse train transmitted through the transmission line;
• a delay time difference compensator for compensating delay time differences between individual optical pulses of the multi-wavelength optical pulse train, the delay time differences occurring when the multi-wavelength pulse train is transmitted through the transmission line;
• and
• a chromatic dispersion compensator for compensating optical pulse spread in a time direction of individual optical pulse of the multi-wavelength optical pulse train, the optical pulse spread occurring when the multi-wavelength optical pulse train is transmitted through the transmission line.
