Closed-form analytical expressions for nonlinear noise power FWM density (IFWM) have been derived for Nyquist WDM systems as a function of the optical fiber and system parameters (i.e. dispersion, nonlinearity, power spectral density, and spectral efficiency) in case of near-zero fiber attenuation.

In WDM networks Routing and Wavelength Assignment (RWA) has proved a major challenge in the field telecommunications. Additionally, nonlinear effects have been found to limit the performance of WDM-based systems. In this paper, various RWA algorithms are analyzed in the presence of Four Wave Mixing (FWM). Based on the analysis, the obtained results reveal that the routing algorithm shortest-path-first...
We investigate and demonstrate for the first time the benefit of IM-DPSK signals over NRZ signal in wavelength conversion using Four Wave Mixing in Semiconductor Optical Amplifier. Using this method, we experimentally demonstrate the wavelength conversion at 10 Gb/s with distance of 450 Km (5 span of 90 Km) using Non Zero Dispersion Shifted Fiber (NZDSF) Single Mode Fiber (SMF). The result shows the...
