Spectral efficiency maximization in Dwdm optical systems under the Impact of FWM

Abstract

newlineOptical networks have a significant role to play in the present and newlinefuture global telecommunication networking scenario due to the increasing newlinedemand for larger transmission capacity Dense Wavelength Division newlineMultiplexing DWDM technology provides a cost effective deployment newlinestrategy compared to complete overhauling of existing systems to increase newlinecapacity However the linear and non linear impairments in the fiber channel newlinesignificantly impact the spectral efficiency of long haul high bit rate DWDM newlinesystems The main focus of this research work is to identify strategies to newlineimprove the spectral efficiency of DWDM optical systems in the presence of newlinenon linear effects particularly Four Wave Mixing FWM effect newlineThe Non Linear Schrodinger Equation NLSE is used to study the newlinepropagation behavior of light pulses in optical fibers newline newline
