Time Division Multiplexing (TDM) and Wavelength Division Multiplexing (WDM) are the most popular multiplexing methods. Each of these multiplexing methods has its own pros and cons. Time division multiplex is able to serve only a small number of participants with low speed, however, for reasonable prices. On the other hand, wavelength division multiplex can serve a high number of participants but its price is much higher. In light of these different properties, there is an effort to create a Hybrid WDM/TDM network that would have positive characteristics of both of these multiplexes and at the same time would meet the characteristics of the Passive Optical Network (PON). Hybrid WDM/TDM PON have been simulated using NRZ, RZ and Manchester coding for different bit rates, input power and fiber lengths. The entire topology design was realized using the OptiSystem version 12 software.
