Experimental testing of the Mandelstam - Brillouin scattering features in the erbium-doped optical fiber

Abstract

The paper is devoted to the experimental testing results of the Mandelstam - Brillouin backscattering spectrum in the erbium-doped single-mode optical fiber. Reflectograms of Mandelstam - Brillouin backscattering spectrum, graphic dependences of strain and loss on the basis of research tests are analyzed. Analysis of the experimental results shown considerable differences in dependences of the erbium-doped optical fiber from the same dependences of other fiber types (G.652, G.653, G.655, G.657).
