Paper Abstract

Flat gain EDFA are key devices in long haul DWDM systems. A flat gain is needed to ensure an adequate signal to noise ratio evolution between channels during transmission. The dissipative filter introduced between two sections of doped fiber inside the amplifier can have a small residual reflective contribution at a particular wavelength. We have investigated the impact of such a back reflection and shown it is negligible for EDFA operation.
