Executive Summary

A technique to reduce third order nonlinear distortion in full-duplex Radio-On-Fiber (ROF) transport system which is based on broadband ASE source employing RF amplifier predistorter, Wavelength-Division-Multiplexing (WDM), and optical add-drop multiplexing techniques is proposed and demonstrated. A data stream of 70 Mbps/10GHz (WiMAX) transmitted over 120 Km long-haul fiber link and good Bit Error Rate (BER) performances with better eye-diagram were achieved in the authors' proposed full-duplex ROF transport system. Such proposed full-duplex ROF transport systems is suitable for long-haul microwave optical link.
