Add to ORKGInternational audienceWe investigate a novel distributed Brillouin optical time domainreflectometer (BOTDR) using standard telecommunication fibers basedon single-photon avalanche diodes (SPADs) in gated mode,<i>ν</i> −BOTDR, with a range of 120 km and 10 m spatialresolution. We experimentally demonstrate the ability to perform adistributed temperature measurement, by detecting a hot spot at 100km. Instead of using a frequency scan like conventional BOTDR, weuse a frequency discriminator based on the slope of a fiber Bragggrating (FBG) to convert the count rate of the SPAD into afrequency shift. A procedure to take into account the FBG driftduring the acquisition and perform sensitive and reliabledistributed measurements is described. W...
