SIMULATION SETUP, The simulation for transmission of To experimentally characterize the. Dispersion managed solitons as shown in propagation dynamics of DM solitons a. Fig 1 was performed using OptSim 5 2 by medium amenable to systematic changes in. RSoft a simulation based tool for designing the linear dispersion is required Such. advanced optical communication systems characterization has proven difficult. The Mode locked laser is used for input,pulse generation for multiple soliton. partly because of the complexity in For six spans total accumulated dispersion is. systematically varying the linear dispersion 36 ps nm DCF has dispersion 72. The ultra short optical pulses propagating in ps km nm and length 0 5 km i e total. solid state mode locked lasers are also dispersion is 36 ps nm and fully. dispersion managed compensates the cumulative dispersion in. the loop to zero The optical filter is placed, The simulation setup consist the Six fiber at the end of the loop and has a width of 2 7. span 30 KM each one dispersion nm,compensating fiber span DCF span has.
