In this paper, we analyze the influence of positive and negative third order dispersion (TOD) on soliton interaction. The peculiar nature of soliton as massive particle results in interaction of in-phase soliton, which has resulted in perfect collision in 160[Formula: see text]Gbps system at the interaction point, [Formula: see text][Formula: see text]Km within one collision period of [Formula: see text][Formula: see text]Km. The TOD normally helps in soliton shift from its initial position. We demonstrate how this shifting of TOD helps in preventing the interaction at 2202.6[Formula: see text]Km with an initial relative spacing and pulse width of in-phase soliton [Formula: see text] and 1.77[Formula: see text]ps, respectively. As the TOD has its influence near zero dispersion point of fiber, we choose the dispersion parameter of fiber as [Formula: see text][Formula: see text]ps2/Km. On considering the positive and negative TOD, the interaction was prevented at [Formula: see text], which is characterized in terms of Q-value in a single channel telecommunication system. It is seen that for positive TOD with the values of [Formula: see text] and 0.07[Formula: see text]ps3/Km, the system yielded the Q-value of 88.33 and 54.81, respectively, while for negative TOD with the values of [Formula: see text] and [Formula: see text][Formula: see text]ps3/Km, the Q was 84.47 and 38.25, respectively.
