Abstract
The optical networks are fast, robust and error-free, but there are some nonlinearity hindrances which prevent them from being a perfect medium. The performance of wavelength division multiplexing (WDM) in radio over fiber (RoF) systems is found to be intensely influenced by nonlinearity characteristics within the fiber. In this paper, the performance of WDM network is analyzed using optical filter and various external modulation schemes under FWM nonlinearity effect. Here, the effect of input signal power on FWM is studied. Also, the threshold value of input power for different external modulation technique is calculated and hence duobinary modulation is found to be optimal technique for reducing FWM effect in WDM networks.
