Nonlinear FWM effects management and FWM system performance analysis in ultra wide optical wavelength division multiplexing systems

Abstract This paper has highlighted the nonlinear FWM (fourwave mixing) effects management and FWM system performance analysis in ultra wide optical wavelength division multiplexing systems. The optical output power is measured with the fiber propagation length based on first/second signals and first/second induced signals. The FWM output power is demonstrated with channel spacing, dispersion coefficient and input signal power based on various modulation techniques. FWM system signal per noise ratio and BER are clarified with the dispersion coefficient with different modulation techniques in FWM system. Maximum transmit power per channel is investigated with the propagation fiber length with different modulation techniques. Maximum mixing efficiency is measured with the fiber dispersion coefficients and channel spacing. Normalized conversion efficiency is demonstrated against the operating wavelength. The FWM power penalty is analyzed and measured against input signal power and total fiber dispersion coefficient. Total system bit rate and total system disperstion are clarified in relation to input signal power with/without chirped FBG with NRZ-PSK modulation technique.
