Dense Wavelength Division Multiplexing (DWDM)is a technique that has been developed to improve the channel range and bandwidth of optical fibre transmission systems. Multiple information channels of varying wavelengths are sent on a single fibre The phenomenon of an input signal spreading out as it flows down the fibre is referred to as optical fibre dispersion. Chromatic, modal and polarisation mode dispersion are all examples of dispersion in fibre optic cable. To compensate for such dispersion, this paper introduces two techniques: Dispersion Compensation Fibre (DCF) and fibre Bragg Grating (FBG).In this paper we will explore Pre, Post Dispersion compensation technique with input as RZ, NRZ and MDRZ encoded. This analysis was carried out and simulated using Optisystem17, which took into account a number of variables such as Maximum Quality Factor, Eye Height, and Minimum Bit Error Rate (BER). Results were analysed for different lengths of transmission.
