Abstract

Improving the performance and capacity of optical networks is an on-going research goal. Two technologies which have been the subject of much research are dense wavelength-division multiplexing (DWDM) and optical code-division multiple access (OCDMA). Although the OCDMA system features distinct advantages over the DWDM system, each system suffers from significant limitations. Of the most serious of these limitations for DWDM is inter and intra-channel four-wave mixing (FWM), while OCDMA suffers from multiple access interference (MAI) and intersymbol interference (ISI). We propose and analyse the effectiveness of an optical hybrid system, which combines the OCDMA and the DWDM technologies, to increase system capacity, and in conjunction with an electro optic phase modulator (EOPM), simultaneously overcome the most serious limitation of the DWDM system. With this hybrid system, each wavelength/channel has the ability to carry N number of OCDMA users; hence, the capacity of the system is multiplied by a factor of N. The system is examined using both theoretical and simulation analysis with and without EOPM at different transmitted powers and different transmission distances based on the RZ-OOK modulation format.
