Abstract
Distributed fiber Raman amplifier with incoherent pumping is investigated and the performance is compared to that with the conventional coherent pumping. Increasing the spectral bandwidth of incoherent pumping source will results in reduction of Raman gain linearly and gain ripple exponentially, and degradation of noise figure up to 1 dB, compared to coherent pumping with the same pump power.
