摘要：Optical CDMA playing significant roles to extend from local area networks to longer span telecommunication type networks. In order to play a significant role in these longer span with higher data rate networks. Optical CDMA code Prefer to have OFDM technique. In this letter, combine SAC-OCDMA with OFDM, operate high data rates and propagate with high fidelity over fiber links. The design of hybrid system with code weight equal to 2 for operation at 10 Gb/s and evaluate their propagation over an existing 100 km network link by means optisystem software. The proposed system using multi diagonal (MD) code gives a good performance based on bit error rate (BER) and long distance. As a result, the BER improved 10^-4 for the OFDM-OCDMA than conventional OCDMA systems at distance 100 Km, as well as the data rate reached to 10 Gbps with desired bit error rate (BER).
