This paper introduces the principle of distributed optic fiber sensing system. The relationship among Brillouin intensity and optical fiber temperature and strain was simulated, and the optic fiber sensing system based on spontaneous brillouin scattering was designed. The experiments on G.652 optic fiber was finished under heating and tension condition, and the signal acquired by the computer was also analysed. The relationship among Brillouin intensity, optical fiber temperature and strain were verified. The application prospect of the system is also discussed in the paper.
