Abstract

The theoretical model of Raman optical-fiber frequency-domain reflectometry (ROFDR) which is brought forward in these years is analyzed, and the defect of the model is found. The theoretical model is consummated by regarding the Bose-Einstein factor as the function of temperature. Because the temperature changes slowly, the relation between the frequency and time is studied, and the model between the D domain and z domain is given. The emulational result is presented. By the corrected method, the corrected calculation temperature is almost accordant with the real temperature, and the error is less than that is reported.
