Abstract :The backscattering spectrum of G652 and DCF optical fiber have been measured. In the Stokes range ,the first order and second order Raman backscattering spectrum have been observed. In the anti - Stokes range ,the first order Raman backscattering spectrum has been observed. In the Stokes and anti - Stokes range ,ZX backscattering spectrum has been first observed. The backscattering effect of optical fiber has been applied to fiber Raman amplifier
and distributed optical fiber Raman temperature sensors system. The operation principle and configuration of dis2 tributed optical fiber Raman temperature sensors system have been discussed. The experimental results have been got .
Key words :optical fiber ;Raman backscattering ;Rayleigh backscattering ;Raman temperature sensors system;Raman amplifier.
