Two Novel Methods for Analyzing Multipath Interference in Distributed Fiber Raman Amplifiers
Based on the summarizing and comparing the analyzing methods in existence for multipath interference (MPI) resulted from backward Rayleigh scattering in distributed fiber Raman amplifiers, two novel methods are presented. A simple analytical expression is developed in the first method. The evolution of optical powers within each step is calculated by a semi analytical method in the second so that the MPI calculating time can be saved and the precision can be improved.
