| description | The invention relates to a system and a method for automatically testing and calibrating property indexes of ROTDR (Raman optical time-domain reflectometry). The system comprises a system host, wherein the system host is connected with one end of the tested ROTDR, and the other end of the tested ROTDR is connected with a 1*8 low-loss optical switch; a first channel to an eighth channel at the other end of the 1*8 low-loss optical switch are respectively connected with an optical fiber of which the temperature coefficient is to be tested, six standard monomode or multimode optical fibers with different lengths, and a standard optical fiber; the other ends, connected with the third channel to the seventh channel of the 1*8 low-loss optical switch, of the standard monomode or multimode optical fibers are respectively connected with optical fiber fixed-length heating devices with same or different lengths; the optical fiber of which the temperature coefficient is to be tested is wound on a variable-length optical |
