Passive Optical Network (PON) have garnered interest in recent years from network providers and researchers alike owing to their tremendous economic advantages for application in last mile services and optical sensing. PONs introduces a good data transmission rate and large bandwidth. We have demonstrated a bidirectional PON system based on a reflective semiconductor optical amplifier (RSOA) with Array waveguide grating AWG at the channel and the data rate for downstream signal equals to 10Gbps and for the upstream equals to 1Gbps so this network is classified to GPON Standard and We have performed a detailed comparison between RSOA and Reflective filter Bidirectional according to the system type. We have also implemented a combination with RSOA and optical wavelength division multiplexing (WDM) techniques by using AWG to simplify the access network architecture. The system allows different optical network unit (ONU's) to be fed by a common fiber. Different wavelength channels can be allocated to different BSs depending on user requirements. The combination of two devices has been performed to provide high bit data rate and wide bandwidth in WDM-PON. We have designed three types of PON, the first system by using RSOA at (ONU) without AWG at the channel, the second system by using RSOA with AWG and finally system by using reflective filter bidirectional with AWG. We showed the results of simulation for all three systems and we made comparison with them. Several measurements are found; the eye diagram, Bit Error Rate (BER) curves for both upstream and downstream, BER with the variation of input power.
