In the modern era good communication systems are the need of the hour. The radio over fiber technologies are a good alternative For the future provisions of wireless communication, Broadband, and Multimedia since it introduces a good data transmission rate and large bandwidth. We have demonstrated a bidirectional radio over fiber ROF system based on a reflective semiconductor optical amplifier (RSOA) using different modulation technique according to the system.We have also implemented a combination of SCM-ROF and optical wavelength division multiplexing (WDM) techniques to simplify the access network architecture. The combination of two different types has been performed to provide high bit data rate and wide bandwidth in cellular communication. The system allows different Base Stations (BS's) to be fed by a common fiber. Different wavelength channels can be allocated to different BSs depending on user requirements. Our Set-up model consist of both upstream and the down-stream data transmission. Within the down-stream AWG multiplex the signal and behaves sort of a multiplexer at the OLT aspect and demultiplex the signal at the ONU aspect. And similar is the case with the up-stream communication system. We tend to developed analytical model for learning the impact of the transmission impartment more over as the AWG characteristics on the BER performance of the WDM PON by incorporating the novel spectral-to-spectral domain transformation technique. Many measurements are found; the Variation in Gain, Q Factor, BER, OSNR, Penalty Power curves for both uplink and downlink, RSOA gain curve and noise figure with the variation of input power and temperature for each system.
