Precision time domain reflectometry in optical fiber systems using a frequency modulated continuous wave ranging technique
Abstract
This paper describes a novel optical time domain reflectometer which uses a frequency-modulated single-mode semiconductor laser as the optical source. The new system offers a potential distance resolution of the order of 1 mm over ranges limited by the source linewidth. In this paper, a theoretical assessment of the features which determine the available performance of the system is followed by some experimental results which confirm these general trends. Applications of this system include short range fault location in situations where resolution of the order of centimeters is required, and as a novel discrimination technique for optical sensor multiplexing systems.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
