Abstract
The authors demonstrate a novel Raman-based distributed temperature sensing (DTS) system using a laser source at a wavelength of 1.65 μm, which permits monitoring of temperature in active transmission lines. This Raman-based DTS system has been demonstrated utilising conventional telecommunications singlemode silica fibres over a range >10 km, whereby spatial resolution of 10 m and temperature resolution of 4°C were achieved
