An average gain level of 22.8�dB and overall gain variation of 3�dB within C and L band regions are achieved. The gain flatness bandwidth of 60�nm from 1530 to 1590�nm are obtained. A comparison with a single pass parallel hybrid fiber amplifier is presented. This comparison showed an average gain level of 38.5% higher than single pass-structure utilizing only 650�mW of Raman pump which is 18.7% lower. � 2020, Springer Science+Business Media, LLC, part of Springer Nature.
