Here, we study the influence of Intra pulse Raman Scattering (IRS) and Self-Steepening (SS) effects on in-phase soliton pulses in 160 Gbps telecommunication system. With the initial spacing between soliton pulses chosen to be qo=5.28, the characteristics feature of soliton interaction is studied numerically by Perturbation theory. Secondly, the effect of higher order effects in shifting the soliton temporally is studied using Method of Moments. Finally the temporal shift caused by these higher order effects (Intrapulse Raman Scattering and Self Steepening) in preventing the soliton interaction at respective Interaction point (Ip) is realized in 160 Gbps telecommunication system and the results are characterized in terms of Q-factor. © 2015 IEEE.
