Abstract

We describe measurement techniques for establishing a standard reference fiber with well characterized group index and time of group delay. Evaluation of an interferometric method indicates that fiber group index can be determined with a total estimated uncertainty of about 0.03 percent in small samples. Group delay of the reference fiber was measured with an overall uncertainty less than 0.004 percent in a 7 km waveguide. We discuss the application of a standard reference fiber to calibration of the distance measurement accuracy of an optical time-domain reflectometer (OTDR).
