Abstract
Optical frequency domain reflectometry (OFDR) circuitry to perform tasks on an optical fiber to generate calibration or correction data for calibrating or correcting a reference OFDR data set. A segmented technique is used which permits precise and accurate determination of the correction data for even initial and long fiber lengths. Correction information for each segment is stitched together to generate the correction data for the fiber.
