Abstract
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.
