2-cm spatial resolution over 40 km realized by bandwidth- division phase-noise-compensated OFDR
spatial resolution bandwidth- division noise-compensated OFDR
2011/5/18
We propose a bandwidth-division phase-noise-compensated optical frequency domain reflectometry technique. Using this approach, we realize a spatial resolution of 2 cm over 40 km in a normal laboratory...
Sub-cm Spatial Resolution Reflectometry over 10 km Based on Phase Noise Compensated OFDR with Third Order Sideband Sweeping
Sub-cm Spatial Resolution Reflectometry Phase Noise Compensated OFDR
2009/7/15
We describe PNC-OFDR employing 3rd order sideband sweeping to realize a broader frequency sweep span. We achieved a sub-cm spatial resolution over a 10 km measurement range.
Evolution of Backscattered Polarization in High-PMD Fibres Measured by Phase-Noise Compensated Optical Frequency Domain Reflectometry
Backscattered Polarization High-PMD Fibres Measured Phase-Noise Compensated Optical Frequency Domain Reflectometry

The evolution of backscattered polarization in high-PMD fibres is measured by phase-noise compensated optical frequency domain reflectometry with a 25 cm spatial resolution and a 7.5 km measurement ra...
40-km Range, 1-m Resolution Measurement Based on Phase-noise- compensated Coherent Optical Frequency Domain Reflectometry
