Abstract :
Four-wave mixing (FWM) is a nonlinear phenomenon in optical communication system that introduces undesired interferences on wavelength division multiplexing (WDM) application for radio over fibre (RoF) broadband access networks. This impairment remarkably degrades the RoF system´s performance. In this paper, the proposed fully-photonic Digitizaed RoF (DRoF) system´s performance is investigated with utilizing different uniform and non-uniform WDM schemes. The simulation results demonstrated that uniform WDM application increases power penalty at central station about 2 dB higher than non-uniform wavelength allocation plan.
