In this werk, the effect of soliton propagation due to interplay between Self-Phase Modulation (SPM) and Group Velocity Dispersion (GVD) is demonstrated in anomalous regime (β2<0 or D>0). The telecommunication system of bitrate 10 and 40Gbps is implemented with Enhanced Large Effective Area Fiber (E-LEAF) as a data transmitting fiber. The combined effect of GVD and SPM is noted by matching the dispersion length (LD) and non-linear length (LNL,) with soliton period of 247.7206Km and 15.48Km for bitrate of 10Gbps and 40Gbps respectively. The interaction between two soliton propagating in phase to each other in same direction are found to be at 49108.59Km for 10Gbps system and 3069.15Km for 40Gbps system for the relative spacing (q1/2) of 529. It is seen that the collision can be avoided by increasing the soliton separation which is evident from 10 Gbps system, such that the collision length (LcoII) is much greater than transmission length (LT). © 2014 IEEE.
