Abstract

Frequency-modulated continuous wave (FMCW) measurements of Rayleigh backscattering and Fresnel reflection from 95-km fiber have been demonstrated by using a compact piezo-electrically-tuned sub-kilohertz-linewidth fiber laser. This technique enables ultra-long fiber fault location in optical transmission systems. The high sensitivity (over-80dBm) of the long-range backscatter measurements without using optical amplifier are benefit from the extremely long coherence length of the sub-kilohertz linewidth fiber laser, which has been estimated to be 210 km in air.
