Buy 80km sfp+ dwdm modules c21 and c51. On this scenario a don¹t have a EDFA, only put these sfp+ and I have link on other side( 60km) but I have a -19dbm and other side I have -21dbm( ddm sfp+ output).. I think I have a better signal than this because I use 80km sfp+ and my distance is 60km can I have a chromatic dispersion? I think to use a EDFA, but i¹m not sure this if I have a chromatic dispersion I have to use a DCM not a ADFA or a booster Right?!
