Abstract

We report the results of an investigation into the signal characteristics and behavior of an instrument used to calibrate Optical Time Domain Reflectometers. This instrument implements the Telecommunications Industry Association standard TIA/EIA-455-226 ?External Source Method.? Results of calibrations performed at various US Air Force Precision Measurement Equipment Laboratories have included some anomalous pulse delays and our efforts were focused on identifying the cause and developing corrective procedures for this anomalous behavior. We also describe the measurement method and associated uncertainty analysis used to calibrate optical fiber delay lines employed in the calibration of the OTDR calibrator.
