Design and evaluation Fiber-to-the-Home network based on DCS code

In this paper, we propose a new design of Fiber-to-the-Home (FTTH) network based on Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA). The FTTH network based on SAC-OCDMA system is tested by employing the Dynamic Cyclic Shift (DCS) code. Whereas, the DCS code is selected due to reduced and mitigates the effect of Multi Access Interference (MAI) in comparing with existing SAC-OCDMA codes. The AND subtraction technique is employed at the at the receiver part of the FTTH network structure due to its compatibility with DCS code to suppress the effect of the MAI. The results, which are obtained mainly from experimental simulations, are presented. In the simulation analysis, the study focused on: the effect of distance, data rate, and noise power on system performance. Finally, Simulation results show that DCS code is expected to become more important in the future of the FTTH network environment.
