The research present status and development of distributed optical fiber temperature sensing network based on light scattering was described. The distributed optical fiber temperature sensors based on Rayleigh scattering, Raman scattering and Brillouin scattering were mainly represented. And the application of optical fiber sensor in high voltage cables and eleetrieal power line supervision were mainly introduced. The sensing light-electrical cable substituted for original electrical cable and optical fiber cable was discussed. The developing three-in-one trend of optical communication, power transmission and sensor was also analyzed.
