Implementation of an All-digital Receiver for WDM/SCM-PON Subscriber Networks

Wavelength division multiplexing/sub-carrier multiplexing-passive optical network (WDM/SCM-PON) is the most flexible and cost-effective technique to transmit multimedia signals with varied formats and speeds. In this paper we propose an all-digital receiver structure supporting up to high bit rate of 120 Mbps for a WDM/SCM-PON subscriber network. The proposed receiver is implemented on a single-chip FPGA and its performance is verified by experimental results.
