Abstract

Numerical assessment of temperature uncertainty of Raman-based distributed temperature sensor is taken out in this paper. The sensing system utilized a modified loop-configuration to avoid stimulated Raman scattering and wavelength dependent loss. The experimental results show that the temperature accuracy reaches 0.74°C (RMSE) between -65°C to 300°C with 2 km fiber under test.
