We develop a low complexity computational model for the gain profile and amplified spontaneous emission noise for broadband counter-pumped Raman fiber amplifiers. The proposed model is based on two adjustment parameters used to account for the interactions between the pumps. The obtained results show a good agreement between experimental measurements and detailed numerical simulations, for different combinations of pump wavelengths and pump powers, with a processing time several times lower than the time taken by a detailed numerical model.
