In this paper, the dispersion maps are compared in the presence of fiber nonlinearities in 10 and 40 Gbps carrier suppressed return to zero (CS-RZ) systems. It is observed that the hybrid-compensation is the best dispersion mapping technique, which reduces the BER produced due to the fiber nonlinearities to the more extent than that of pre-compensation and the post-compensation. This technique increases the repeater length almost up to double than that of pre- and post-compensation. The pre-compensation shows the highest BER followed by post-compensation.. It is also observed that with increase in the input bit rate, the BER for all three compensation techniques is also increased. But the still the hybrid-compensation reduce the BER up to more extent. The BER also increases with the increase in input optical power due to nonlinear impairments on the link at high powers.
