| Summary: | This paper demonstrates a novel Raman-based distributed temperature sensing (DTS) system using a laser source at a wavelength of 1.65µm, which permits monitoring of temperature in active transmission lines. This Raman based DTS system has been demonstrated utilising conventional telecommunications single-mode silica fibres over a range exceeding 10km, spatial resolution of 10m and temperature resolution of 4°C was achieved. |
