The Experimental Testing of the Mandelstam - Brillouin Backscatter Parameters in Some Varieties of Optic Fibers

This work presents results of testing (experimental research) parameters of the Mandelstam - Brillouin backscattering for some types of optic fibers. Their main acoustic-optical characteristics are analyzed. Experimental reflectograms of the Brillouin reflectometer are presented. The Brillouin frequency shift for each considered type of optical fibers is estimated. Frequency dependence profiles of the Mandelstam - Brillouin backscattering parameters are given. The characteristics of new varieties of single-mode optical fibers are presented. A comparative analysis of their parameters with the characteristics of previously researched optic fibers is carried out.
