本文提出了一种基于正交频分复用（OFDM）和光外差的WDM无源光网络（PON）。系统采用OFDM和相干接收技术，实现了高弹性的带宽分配和优良的传输性能。该网络采用光外差实现无线接入，无需增加射频源。我们从误码率、覆盖面积和接收眼图等方面对系统的性能进行了评估，并得出该网络具有优良的有线/无线接入性能。
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.
