摘要：

A wavelength-division-multiplexer (WDM) was used to extract the Ramam scattering signal from a data fiber. The temperature performance of Raman scattering spectrum was studied theoretically and experimentally. On the base of this study a distributed fiber-optic temperature sensor (DFTS) system was developed. The sensing distance was 4km. The temperature accuracy and the distance resolution reached to +/-1 degrees C and +/-1m, respectively. The system is stable and adequate for commercial usage, such as the power industry, the underground tunnel the subway, the pipe laying, and also for the mission applications, such as the warship and the airplane.
