Hi Abhishek,
Unfortunately, I don’t have an access to OptiSystem right now to run your schemes. However, according to your question about the choice of amplifier (Raman & EDFA) I would recommend you to take a look at the following link (if you have not seen it yet): http://www.researchgate.net/profile/Juliano_De_Oliveira/publication/257362781_Hybrid_Distributed_RamanEDFA_Amplifier_with_Hybrid_Automatic_Gain_Control_for_Reconfigurable_WDM_Optical_Networks/links/0c960525063b2dc5dc000000.pdf
