As a scheme of multiple access, Optical Code Division Multiple Access (OCDMA) technology has many outstanding advantages such as large capacity, high security and excellent anti-interference ability, which make OCDMA a forefront topic of research in all-optic access networks. In this thesis, we introduce OCDMA technology in detail, especially 2-Dimensional (2D) OCDMA system. A novel signature code named nMPHC (new-Modified Prime-Hop Code) is designed for 2D system and its performance is analyzed in different system configurations under various circumstances against two similar-structured codes named PHC (Prime-Hop Code) and MPHC (Modified Prime-Hop Code). Results show that nMPHC can reduce the same amount of system complexity by decreasing less supported users than MPHC and nMPHC outperforms MPHC in most cases, it is proved that nMPHC is a good candidate for future 2D OCDMA system.
