The quasi-NLS equation describing propagation of ultrashort pulses in dispersion decreasing fiber is obtained. Using numerical simulation
a complete analysis is made for the generation of soliton trains in such fiber with dual-frequency beat-signal as input. The performance shows quite different when fiber loss is taken into account
so neglect of loss must be cautious.
