Four Wave Mixing Nonlinearity Effect in WDM Radio over Fiber System

The optical networks are fast and error free but due to some nonlinearity effects, its performance degrades. The performance of wavelength division multiplexing (WDM) in radio over fiber (RoF) systems is found to be strongly influenced by nonlinearity characteristics inside the fiber. In this paper, we have studied the effect of four wave mixing (FWM) as one of the influential factors in the WDM for RoF using Optisystem Software.
