This paper presents a numerical simulation of the nonlinear pulse propagation effect on the distributed strain and temperature measurement with the Brillouin optical time-domain analyzer (BOTDA) . The pulse shape is deformed by the stimulated Brillouin scattering and the carrier frequency is shifted by the self phase modulation as the pulse propagates down the fiber. As a result, the Brillouin frequency of fiber (i.e. strain and temperature) measured with the BOTDA becomes different from the true one. The difference can be more than several mega hertz that is larger than the noise-caused measurement error. |
