Thank you damian for your reply,i do not understand which model i have to use whether it is dynamic or ARA in case of raman amplifier and EDFA. I have attached a file ,please look at this.
Ravil thank you too,I have one more problem,when i use this system in optisysyetm 7,noise figure at the dual port analyzer comes out to be 4db and less than that.But same systeem in optisystem 13 gives >50 db NF.Why it is so?
