Abstract(in Japanese) (See Japanese page)
Abstract(in English) We demonstrated sub-cm spatial resolution reflectometry over a 10 km range based on PNC-OFDR employing optical 3rd order sideband as a test light for a broader external frequency sweeping. It was theoretically derived that the 3rd order sideband was generated by two LN-IMs arranged in series. The obtained spatial resolution was sub-cm over 10 km, and the sensitivity (relative to the Rayleigh backscattering level) was about -25 dB for all measurements. This means that the concatenative reference method for PNC-OFDR with 3rd order sideband sweeping worked very well over a 10 km range. It appears to be almost impossible to realize both a sub-cm spatial resolution and a sensitivity of -25 dB simultaneously over 10 km with any conventional reflectometry technique.
