Deploying a PON using multimode fiber in the access network is viewed as a costeffective solution. However, a multimode fiber link exhibits a time-dispersive nature. To cope with this problem, an OFDM transmission method is used. In this work, a comparison study on several duplexing methods for this system was performed to decide upon the recommended method for the system. The choices that were examined are: TDD, FDD, WDD and SDD (time-, frequency-, wavelength- and space- division duplexing). Based on the following criteria: channel characterization, flexible bandwidth proportion, crosstalk & beat noise impairment, components-saving and system capacity, it was concluded that SDD is the most feasible one among other choices, immediately followed by WDD.
