We have developed a model for intra-channel impairments in dispersion-managed systems and validated it using numerical simulations. We have shown that intrachannel impairments can be reduced using optimal precompensation. We have studied the intrachannel penalty for different modulation formats, and results show that the optimum precompensation is independent of modulation format. The intrachannel penalty decreases as the spectrum of the modulation format broadens.
