Abstract

We have analyzed the combined effect of pump-intensity noise and reflections on the performance of counter-pumped Raman amplified systems. The required level of pump-intensity noise was evaluated for negligible enhancement of multi-path interference (MPI). We have also investigated the enhancement of pump-to-signal crosstalk caused by the reflections occurring within transmission fiber. We found that a high reflection (larger than -20 dB) within effective length of fiber could increase the effect of pump-to-signal crosstalk even for the counter-pumped Raman amplifiers.
