In this research, we study a nonsimultaneous threesoliton collision in the presence of thirdorder dispersion in WDM systems. The interaction between solitons may be viewed as an inelastic collision in which energy is lost to continuous radiation owing to nonzero thirdorder dispersion. We develop a perturbation theory with two small parameters; the third order dispersion coefficient d_{3} andthe reciprocal of the interchannel frequency difference, 1/β. In the leading order the amplitude of the emitted radiation after each collision is proportional to d_{3}/β^{2}. In addition, the only other effects up to the combined third order of the perturbation theory are phase changes and position shifts of the solitons. It has been shown that after each collision the rate of emitted energy is the same.

The effects of pulse width and their separation on the interaction distance and interaction length are investigated. Having ignored the effect of loss and third order dispersion coefficients, we found that the interaction distance changes in a quasiGaussian manner as a function of two interacting pulse separation. The effects of varying pulse widths and constant pulse separation and the reverse (i.e., the constant pulse widths and varying pulse separation) on the interaction length and the interaction distance have been investigated. It is found that in either case, the interaction distance and interaction length change exponentially with pulse width.
