The effect of the dispersion map and nonlinearity on performance of 107 Gbps on-off-keying with different return-to-zero duty-cycle over long-haul transmission is investigated by simulation. It is observed that without existence of nonlinearity, different dispersion maps perform almost similar. However, performance difference between different dispersion maps becomes noticeable when nonlinearity presents in the system. In existence of nonlinearity, at any launched power, the map with around 10% dispersion pre- and 90% post-compensation shows the optimum performance.
