Abstract
The evolution of noise in transmission systems with multiple spans featuring forward pumped distributed Raman fiber amplifiers has been investigated experimentally and by numerical simulations. We found evidence that the transfer of relative intensity noise from the pump to the signal reveals characteristics of a nonlinear process, which cannot fully be captured by a Gaussian random variable added...
