Optical fiber sensor is a newly developed technology. This paper presents
a distributed fiber temperature sensing system based on spontaneous Raman scattering
its applications and configuration design. The principal operation of the system pumped by a pulsed laser is analyzed emphatically. A new type of WDM based on the thin film filters used in Raman scattering is designed.
