Advances in soliton transmission in which dispersion management plays an important role in increasing the power margin and the dispersion tolerance in TDM and WDM systems are presented. The quality of the dispersion-managed soliton is compared with return to zero (RZ) and nonreturn to zero (NRZ) pulse transmission at zero group velocity dispersion (GVD). This is because the dispersion allocation enables to keep the transmitted pulse energy at a high level as the GVD in each fiber segment is much larger than the average GVD. That is, pulse boardening occurs due to large GVD, so that a larger energy is needed to maintain its intensity. In other words, this is a power enhancement factor.
