| Abstract(in English) | We show that the dominant noise of long range optical frequency domain reflectometry (OFDR) after compensation process for the phase noise of the optical source results from environmental acoustic perturbation rather than the compensation process. If both the auxiliary and measurement interferometers are insulated against acoustic noise, the phase noise compensation scheme works almost ideally even over a 40-km range, with at least sixteen-fold concatenation. Although the spatial resolution achieved by phase-noise compensated OFDR (PNC-OFDR) is influenced by the environmental acoustic perturbation, a resolution of ～20cm was achieved over 20km in a relatively noisy laboratory environment, by insulating the auxiliary interferometer and employing higher frequency sweeping rate. This approach can be used for mid to long range network diagnosis with a narrow spatial resolution, which is unachievable with other technologies. |
