摘要：Wavelength division multiplexing (WDM) technology allows several channels to be routed through the same fiber cable with different wavelengths. In WDM systems dispersion , loss , attenuation , and non-linear effects are the issues that degrade its performance. Dispersion is a main limiting factor in high speed optical WDM system. In this paper 8 channel WDM system at 40Gbps and 125km length of optical fiber with 25 km length of DCF has been investigated for three dispersion compensation techniques i.e. pre , post and symmetric using DCF. All three methods are compared in terms of different parameters such as Q-factor, BER by using OptiSystem simulator .It has been observed that the set-up requires appropriate matching between EDFA gain and length of optical fiber for best performance.
