Abstract

Distributed temperature sensor based on Raman scattering is investigated. The ratio of intensities in Stokes and anti-Stokes bands reveals the temperature of a fiber section. A spatial resolution of around 1m is obtained by use of Incoherent Optical Frequency Domain Reflectometry. An accuracy of ±2K is demonstrated over a 16km single-mode fiber, which represents a new record. A brief discussion on the choice of the sensing fiber is also given.
