Abstract
Due to the polarization sensitivity of Raman gain and the random nature of PMD in the fiber the gain of fiber Raman amplifier not only depends on the polarization states of the input signal and pump but also fluctuates over a wide range during a relative long time. The fluctuations are related to the PMD parameter of the fiber and the pumping scheme. In this paper the statistics of the gain fluctuations in an amplifier employing bi-directionally pumping schemes is studied. The ratio of forward to total pumping power is optimized to achieve best trade-off between the OSNR and nonlinear distortions beforehand. The results obtained are useful for the further optimization of bi-directionally pumped amplifiers.
