DISPERSION COMPENSATION USING THE INVERSE TRANSFER FUNCTION OF FIBER OPTIC CHANNEL

Abstract

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