A Novel Scheme for OFDM-PON Based on Polarization Multiplexing and Heterodyne with Colorless ONUs and Wireless Access

Abstract A novel orthogonal frequency division multiplexing passive optical network (OFDM-PON) is proposed in this paper. By using polarization multiplexing (PoLMUX) technology, this network can not only support source free in optical domain but also in electric domain. This network can also realize wireless access by optical heterodyne technology. The optical carrier suppression and separation (OCSS) technology is used to improve utilization rate of the optical source. Besides, the cross-modulation technology is used to mitigate the influence of the Rayleigh backscattering. By simulation, the functions mentioned above are demonstrated. And simulation results show this network has good performance.
