Abstract
Investigation of a method to extend-range distributed temperature and strain sensor based on detection of the Brillouin frequency shift combined with counter-propagating Raman amplification has been realized. 50-km-range of standard single-mode silica fiber with great results has been sensed. Results of an experimental investigation of Brillouin frequency shift at different fibers.
