“…When an information carrying signal is transmitted over the optical fiber communication system some losses occurs due to distortion, attenuations, dispersion, absorptions etc [1]. One of the foremost limiting factors in fiber optic communication which accounts for the degradation in the performance is dispersion.…”

“…The reason for chromatic dispersion is the dependence of refractive index and hence the group velocity of silica on the wavelength used for data transmission [4]. Erbium Doped Fiber Amplifier (EDFA) can be used to compensate dispersion in a optical fiber [1]. DCF and FBG are other techniques which can be used for compensation of dispersion in optical fiber link.…”

In optical fiber Communication system dispersion compensation has become one of the major topics of importance and research nowadays. This is because any presence of dispersion might leads to pulse spreading which might cause inters symbolic interference (ISI) and which leads to signal degradation. In this paper six different model are considered for dispersion compensation. Dispersion compensation fiber (DCF) is used to design first three models by using its three different configurations of pre-compensation, post-compensation, symmetrical compensation and Fiber Bragg Gratings (FBG), uniform FBG, IDCFBG are used for designing rest of three dispersion compensation models. Single channel optical system length of 100 km with data rate of 2.5 Gbps and 10 Gbps is used to design each model and is simulated by using optisystem software package. All the designs are compared with respect to the quality factor (Q-factor) and bit error rate (BER). With the outcome of the simulations results it is seen that post–compensation DCF model is the promising approach.
