Abstract
We report that pump-noise induced four-wave mixing effects can be serious for some nonzero dispersion-shifted fiber using distributed Raman amplification. Moreover, we find that such an effect strongly depends on the spectral structure of the pump, and can be suppressed by expanding the effective spectral width of the pump.
