N-SOLITON (N >2) INTERACTION IN THE PRESENCE OF THIRD-ORDER DISPERSION OF OPTICAL FIBERS

N-soliton (N > 2) interaction in optical fibers including third-order dispersion is simulated numerically. In equal amplitude soliton transmission, the coalescence resulted from the mutual interaction among N solitons still exists, while in the unequal case, soliton interaction can not be removed but becomes more serious due to the effect of third-order dispersion. Therefore, we can not consider third-order dispersion as an utilizable factor for removing soliton interaction.
