Paper Abstract

A dynamic gain control (DGC) technique for the multi-wavelength-pumped fiber Raman amplifier (FRA) is presented. It introduced an all-optical feedback to inject a portion of the signal power into the system by using a variable attenuator. The stable performance of the proposed gain-clamped FRA was simulated and the noise performance was also discussed.
