Abstract A SAC-OCDMA-OFDM-DWDM system using a flat optical frequency comb generator and a coherent communication system is proposed in this research. The objective is to develop a novel OCDMA communication system that is appropriate and dedicated to multiservice networks. A comparison between the two codes, EDW and RD, has been presented. It has been concluded that the RD code system has better performance in terms of robustness and number of users than the EDW code. By analyzing the BER for several symbol rates and comparing it to the pre-FEC threshold, the proposed system demonstrates its effectiveness against linear and nonlinear effects. Performance evaluation of the proposed system is carried out via co-simulation of OptiSystem and MATLAB.

AbstractA new approach to generate high-quality optical frequency comb (OFC) with good flatness, high bandwidth, and tunable frequency spacing is proposed. The OFC generator includes a polarization modulator and an intensity modulator (IMS), and the polarization modulator is modulated by a radio frequency multiplication circuit. The theoretical analysis model of the proposed scheme is established. The experiment stimulation results show that 35-line OFC with tunable frequency spacing and spectrum flatness of 0.3 dB and side-mode suppression ratio of 15.53 dB is gotten easily by adjusting the amplitude and frequency of the RF and the direct current bias voltage of the modulators. The stimulation results are in good agreement with the theoretical model.
