40 km long-range Raman-based distributed temperature sensor with meter-scale spatial resolution

We propose a new Raman based distributed measurement technique which allows for temperature sensing over nearly 40 km of graded index multimode optical fiber with meter-scale spatial resolution and temperature accuracy better than 3°C.
