In this paper, we propose a WDM radio-over-fiber (RoF) passive optical network (PON) based on orthogonal frequency-division multiplexing (OFDM) and optical heterodyne. With OFDM and coherent receiving technology, the system achieves high, elastic bandwidth allocation and excellent transporting property. Using optical heterodyne, the network implements the wireless access without adding a radio source. We evaluate the performance of the system in terms of bit error rate, coverage area, and receiving eye diagram and obtain the network as an excellent wire/wireless access property.
