Abstract:

We report the results of an investigation into the signal characteristics and behavior of an instrument used to calibrate optical time domain reflectometers (OTDRs). This instrument implements the Telecommunications Industry Association standard TIA/EIA-455-226 "External Source Method." Previous results of calibrations performed at various US Air Force Precision Measurement Equipment Laboratories have included some anomalous pulse delays. Our investigation focused on identifying the cause of this anomalous behavior and developing corrective procedures for it. 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.
