N2 - We report the possibility of measuring the temperature distribution along a conventional single-mode fiber by coherent optical frequency reflectometry using a self-sweeping fiber laser and Rayleigh scattering of light by inhomogeneities frozen into the fiber. To this end, the problem of increasing the sensitivity of the reflectometer to a level of about –120 dB mm–1 is solved. A linear relationship is shown between a change in fiber temperature and a shift in the reflection spectrum of 4-cm long heated fiber section with a sensitivity of ~2 GHz C°–1.
