Paper Abstract

The development of a single mode optical fiber standard, for the distance scale calibration of Optical Time Domain Reflectometers (ODTRs) is presented. The configuration of the standard is based on a Recirculating Delay Line (RDL) which generates a series of reflections at constant intervals of time; such reflections are used as distance references using a nominal group index of the fiber. The optical modulation-phase-shift technique was used to characterize the transit time of the reference fiber, at the 1310 nm and 1550 nm communications windows. The characterization method provides the sensibility coefficients of the two dominant influence quantities, optical signal wavelength and temperature of the fiber.
