This paper investigates the Four-Wave Mixing (FWM) issues in ultra-band dense wavelength division multiplexing (DWDM) system design using low input power, high optical gain, and modulation format with an optimized duty cycle. Bandwidth and high data rate are key considerations in fiber optic system design. Emerging 5G technologies, internet development demand higher bandwidth, and large data rates, leading to DWDM enhancement in fiber optic communication. This introduces more fiber nonlinear effects and limits DWDM system performance. Hence, the study of fiber nonlinearities using various design parametric analysis is necessary to improve the long-haul fiber-optic system design's data transmission capacity. In this paper, FWM nonlinear issue is studied, and factors that are accountable for deviations in WDM design are analyzed. Simulations are performed to understand system parameters such …
