Abstract
The impact of noise in the pump profile of distributed Raman amplifier (DRA) for extended bandwidth transmissions is investigated. Specifically, a continuous pump generated by a shaped amplified spontaneous emission signal is employed to fit the DRA gain profile to a predefined target. The analysis is performed by comparing the power profiles obtained by the artificial neural networks (ANN) and by conventional numerical models for the Raman amplification process, resulting in errors below 0.5 dB.
