Abstract

We present the longest reported sensing range of temperature change measurement along single-ended optical sensing fibre. The technique is based on spontaneous Brillouin scattering and microwave heterodyne detection. Brillouin frequency shift was used to obtain temperature change at range of 81km with temperature error less than 5C, and spatial resolution of 30m, at relatively low input pulse power of 70mW.
