Paper Abstract

Brillouin scattering properties of a bend-insensitive fiber were experimentally investigated at 850 nm and 1550 nm wavelength using Brillouin optical time-domain analysis (BOTDA). A diversity scheme has been adopted, in which the BFS distribution along the same fiber is acquired at the two operating wavelengths. Based on the different wavelength scaling factor of temperature and strain coefficients, simultaneous measurement of strain and temperature at 1-m spatial resolution has been obtained in a proof-of-concept experiment.
