چکیده

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 we 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 we will eliminated MAI(multiple access interference) and improve BER (bit error rate) , PIIN( Phase induced intensity noise) and make orthogonality between users in the system .We will use AND subtraction detection technique to implement these codes with technique of OCDMA using optiwave system design tool.
