Abstract

In this article, we examined the attenuation and chromatic dispersion induced pulse broadeningduring soliton pulse propagation in a single mode fiber (SMF) neglecting the nonlinearity effect. It isshown by simulation that this pulse broadening and attenuation problems can be eliminated using aproposed equalizer even the dispersion parameter of the fiber changes during pulse propogation. Forthis purpose, Nonlinear Schrödinger Equation (NLS) that characterizes pulse propagation in opticalfibers was solved numerically in Matlab environment with the developed software using split-stepFourier method and the simulation results were shown grafically in 3-D format. Using the simulationsresults, it is observed that the soliton impulse is distorted by broadening and attenuation proportionalto the fiber length.The proposed equalizer compansates these distorsions by narroving pulse widthand increasing the pulse level to the initial value for fiber cable lengths up to 120 km but can not besucessful for longer fiber lengths. We are planning to apply this equalizer for OFDM signals.
