Заголовок статьи: Mechanical strain places detection of the optical fibers in optical cables using Brillouin time-domain reflectometers


Research results of the optical fiber strain and optical cables being under the influence of mechanical forces in various manufacturing processes, using Brillouin optical time-domain pulse reflectometers are presented in this work.
The research results confirmed the advantage of the Brillouin reflectometry method for early diagnostics and detection of local mechanically stressed places of optical fibers. To determine the total elongation of optical fibers, the phase shift measurement method is effectively used.
