本文设计了一种基于偏振复用（PM）和CSRZ-QDPSK的WDM-ROF-PON，可以同时实现有线和无线接入。采用相位调制和QDPSK调制，提高了系统的带宽利用率。采用CSRZ-QDPSK调制方式，ONU内部的无线接入可以节省射频资源，而无线载波的频率可以由奥尔特控制。网络具有可靠的传输特性，包括无线接入和光纤传输。网络也有很好的覆盖范围。
In this paper, we design a WDM-ROF-PON based on polarization multiplexing (PM) and CSRZ-QDPSK, which can achieve wire-line and wireless access synchronously. Using PM and QDPSK modulation, the system improves bandwidth utilization. With the CSRZ-QDPSK modulation, the wireless access in ONU can save RF source and the frequency of radio carrier can be controlled by OLT. The networking has the credible transmission property, including wireless access and fiber transmission. The networking also has excellent covering range.
