Paper Abstract

C+L-band (1530 nm - 1605 nm) discrete fiber Raman amplifiers (dFRAs) with incoherent pumping are investigated considering gain, noise figure, and pumping efficiency with comparison to coherent pumping. It is shown that dFRAs with two incoherent pumping sources can have a gain flatness of less than 0.7 dB over 75 nm bandwidth. Noise performance of dFRAs with incoherent pumping is similar to coherent pumping. The comparison of C+L-band dFRAs with incoherent co-pumping to incoherent counter-pumping shows that dFRAs with incoherent co-pumping perform better due to not only lower but also flatter noise figure, besides increased pumping efficiency.
