Abstract

Raman gain in various optical fibers G652, G653, G655 and DCF (dispersion compensating fiber) and the selection of fibers in discrete broadband Raman fiber amplifiers (RFA) are studied. Using the experimental results from references, we have obtained a polynomial formula of the SRS (stimulated Raman scattering) Stokes spectrum and the effective area of the fibers by sampling and digital fitting. The effective Raman gain coefficients are calculated using the formula. Based on the formula, Raman gains of multi-wave pump RFA in different fibers are obtained with the consideration of arbitrary interaction between pump waves and signal waves. Comparing the pump power distributions and the lengths in the four optical fibers, we propose appropriate selections of optical fibers in Raman fiber amplifiers.
