- Abstract
The results of experimental studies into the Mandelstam–Brillouin scattering characteristics are presented for single-mode optical fibers of various types and manufacturers. The experimental dependences of optical fibers obtained using a Brillouin optical reflectometer (graphs of the distribution of the Brillouin scattering spectrum along the length of the fiber and multireflectograms) are presented. For each type of optical fibers considered, an estimate of the Brillouin frequency shift is given, the value of which, at wavelengths of laser radiation used in telecommunication systems, refers to the microwave range. The frequency dependences of the Mandelstam–Brillouin scattering characteristics of some varieties of single-mode optical fibers with different cutoff wavelengths are presented. A comparative analysis of their characteristics with the characteristics of previously studied single-mode optical fibers is carried out. Optical fibers of similar varieties (but different manufacturers) can have noticeable differences in the frequency response of Mandelstam–Brillouin scattering. A table with the main characteristics of Mandelstam–Brillouin scattering is presented for all experimentally studied single-mode optical fibers.
