Hi Fadil,
Here i am uploading osd file 32 channel wdm system with advanced modulation format of CSRZ using symmetric compensation technique and bit rate of 40 gbps for transmission distance varies from 60 km to 1500 km by just increasing the no of loops, upto 1200 km or more you will get good q-factor and Min. BER. use this as reference you can design for MDRZ AND DRZ modulation formats too.
it is very good design and complex one.
