In this paper, a new method is presented to calculate the execution of Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) network. A new code proposed is Dynamically Cyclic Shift (DCS) code to assess the execution of the network. Bit error rate is the parameter of performance studied. A Dynamically Cyclic Shift (DCS) algorithm is used at the transmitter section and a detection technique called AND-Subtraction technique is used at the receiver. The most astonishing aspect in the detection techniques the reduction of Multiple Access Interference (MAI) and the correlation values lies between 0 and 1, for the developed DCS code. SAC-OCDMA network is more consideration in view of their capacity to totally avoid multiple access obstruction by utilizing code successions with settled in phase cross correlation (lc ). The performance is calculated using the Signal to Noise Ratio (SNR) and the experiment is simulated at 8 Gb/s for a link length of 15 km using optisystemTM ver.12 simulation software from optiwave. The BER obtained is 4.66 × 10–17 using DCS code.
