Estigation and Evaluation of The Combined Effects of DCF And CFBG in Multi-Channel (WDM) System at Ultra Narrow Channel Spacing

Abstract

In WDM system analysis has been carried out to compensate dispersion effects. Three different
scheme is proposed such as alone FBG, alone DCF and DCF+FBG for pulse width
reduction. Results revealed that FBG+DCF provide best results than other techniques in
terms of Q- factor and BER. This system is tested over 100 Km at 50GHz channel spacing
for evaluation as DWDM channels. It is observed that pulse width reduction of 96% done
with combined module and 75 % with FBG. Also proposed module is less expensive than
other two, and best in efficiency
