Abstract :
The optical frequency domain reflectometry (OFDR) based on tunable narrow linewidth fiber laser is studied, including the relation between beat frequency and the distance of fiber under test (FUT). Experimental results show that the OFDR at long-range measurements, about 150 m, with large full width at half maximum (FWHM). At short range, about 1 m, the FWHM increases to 14 cm.
