A distributed optical fiber temperature sensing technique based on the Brillouin amplification architecture is described. The technique takes advantage of the temperature dependency of the Brillouin frequency shift in fiber. In this paper, the structural characteristics of the sensing fiber and the physical properties of the material starting point, in theory, proved that there is a linear relationship between fiber temperature and Brillouin frequency shift. Based on this sensing technique, an experimental system was established. The test data proved the correctness of the theoretical analysis
