Abstract

We report a reduction in the fading noise of Rayleigh-backscattering profiles for coherent optical frequency-domain reflectometry (C-OFDR) which uses a wavelength-tunable narrow-linewidth light source and an external electro-optic modulator. We measured a 100-m optical fiber with a spatial resolution of 30 cm and a dynamic range of greater than 15dB. The fading noise was reduced to 0.13 dB by averaging the spectrum while changing the wavelength and polarization state of the light. This is the best result to date for C-OFDR with a spatial resolution of better than 1 m.
