A novel OCDMA based on wavelength-converter and programmable electrical controller

The paper proposes a novel OCDMA system based on wavelength-converter and programmable electrical controller. The electrical DS (direct sequence spread spectrum)/FH (frequency hopping) in CDMA is used in our system. The designed system doesn't need fiber taps and only very short optical pulses. It integrates the success on the OCDMA and OWDMA techniques.
