Implementation of AWG as A MUX / DMUX at the WDM PON System

PON (PASSIVE OPTICAL NETWORK) is going to be the one of the basic requirement of the future demands of the tele-communication system. The implementation of the WDM-PON along with the AWG is done carefully in the in the system. The AWG is used in both of the transmitter and the receiver side, as a multiplexer and demultiplexer. Our set-up model consists of the both up-stream and the down-stream data transmission. In the down- stream AWG multiplex the signal and behaves like a multiplexer at the OLT side and demultiplex the signal at the ONU side. And similar is the case with the up-stream communication system. We developed analytical model for studying the impact of the transmission impartment as well as the AWG characteristics on the BER performance of the WDMPON by incorporating the novel spectral-to-spectral domain transformation technique. The very main concept of the proposed model is the AWG . The power being captured by the output port of the AWG is not only based on the Gaussian focal field pattern but also to the power spill over the adjacent ports. All the results are strongly supported with the help of the Q factor and the eye diagram which are being executed from the BER analyser at the receiver part of the set up model. At the analysis section the plotting of the different parameter is also demonstrated. As a software Optiwave 7 software is used for the complete analysis purpose.
