A RoF system can further be enhanced by incorporating the dense wavelength division multiplexing (DWDM) technique for bandwidth utilization and ultra high speed communication. In this paper the model for a high speed of 1Tbps, a 40-channel DWDM-RoF system has been designed and simulated where each channel carries data at a rate of 25 Gbps. The performance of and erbium doped fiber amplifier (EDFA) and semiconductor optical amplifier (SOA) for the system has been compared for extremely narrow channel spacing of 0.1 nm, and 0.2 nm at different transmission distance. The Q-factor and optical signal to noise ratio (OSNR) values have been reported for different cases and it is observed that SOA performs linearly and better than EDFA when employed as post amplifier.
