Wavelength Division Multiplex Ethernet Passive Optical Network (WDM EPON), due to its simple configuration and enormous capacity advantage over present access network technology, is considered by many experts to be the promising solution to realize FTTH. In this paper, we proposed a model of WDM EPON system using OPNET, collected the statistical parameters and analyzed the network capacity through simulation. Based on the network topology and WDM technology features, we designed the network configuration to be P2MP in the downstream direction using broadcasting mechanism and P2P in the upstream direction using independent wavelength channels. We studied the MAC protocol stacks under WDM EPON hierarchy and designed the OLT and ONU node modules based on the theoretical models. ONU dynamic registration and MAC mappings of data switching in OLT are the two key technologies introduced in the model to realize the communication within the system. Simulation results approve that WDM EPON system has great bandwidth capacity and extremely little terminal-to-terminal latency, thus displaying great capability advantages and developing prospects.
