The system of Coupled Nonlinear Schrodinger's Equations (CNLSE) is solved numerically by means of a conservative difference scheme. Values of the cross-modulation parameter, alpha(2), are chosen to induce repelling collisions. The resulting waveforms are fitted to soliton profiles and studied via internal parameters including phase velocity to gain insight into the cl dynamics of the repelling collisions. A decaying oscillation of the post-collision profiles is observed and investigated in terms of varying alpha(2) and relative initial velocity of colliding profiles.
