Optical Code Division Multiple Access system (OCDMA) has been important with increasing demands of high capacity and speed for communication in optical networks. Due to OCDMA technique high efficiency is achieved, hence fiber bandwidth is fully used. In this paper, the authors will focus on different codes i.e. MD (Multi Diagonal) FCC (Flexible Cross Correlation), DCS (Dynamic Cyclic Shift) code with BER parameter. Due to this codes they will eliminate MAI (Multiple Access Interference) and improve BER (Bit Error Rate), PIIN (Phase Induced Intensity Noise) and make orthogonality between users in the system.
