An analytical noise figure expression for backward-pumped distributed fiber Raman amplifiers (B-DFRAs) was derived, taking the influence of fiber Rayleigh backscattering into account. The result agrees well with experiment results and numerical simulation, and can be applied to pump power selection in B-DFRAs aiming at low noise figures.
