In the distributed optical fiber Raman photons temperature senser (DOFRPTS) system, spontaneous Raman photons are carriers of temperature signal. On the 2 km optical fiber, 1000 points have been sampled on time used for the measurement of temperature field in space. The position of measurement point was determined by Raman scattering optical time domain reflection (OTDR) technique. Signal and noise of the system have been discussed, the measured temperature accuracy of the DOFRPS system is ±1℃ determined by S/N ratio.
