In this paper, the Four Wave Mixing (FWM) effect on sixteen channels Dense Wavelength Division Multiplexing (DWDM) optical communication system has been compared for different values of channel spacing. The effect of variation in input power of laser array has also been investigated. The effect of dispersion has also being considered in the optical spam of fiber and pre-dispersion compensation technique has been employed to mitigate its effect. The performance of optical communication system has been evaluated in terms of Q-factor, Bit Error Rate (BER) and output from the Optical Spectrum Analyzer. This paper simulates that the FWM effect decreases as the channel spacing increases.

Abstract


In this paper, the Four Wave Mixing (FWM) effect on sixteen channels Dense Wavelength Division Multiplexing (DWDM) optical communication system has been compared for different values of channel spacing. The effect of variation in input power of laser array has also been investigated. The effect of dispersion has also being considered in the optical spam of fiber and pre-dispersion compensation technique has been employed to mitigate its effect. The performance of optical communication system has been evaluated in terms of Q-factor, Bit Error Rate (BER) and output from the Optical Spectrum Analyzer. This paper simulates that the FWM effect decreases as the channel spacing increases.
