Résumé : This PhD thesis focuses on temperature measurement along a standard optical fiber using a photon counter. Current interrogator solutions, based on Brillouin frequency measurement, are range-limited by the signal-to-noise ratio of conventional photodiodes. The use of a photon counter allows for the detection of weaker optical signals and extends the detection range. A BOTDR based on photon counting was developped, in order to measure the temperature variations beyond 100 km
