Paper Abstract

An interferometric technique for the measurement of chromatic dispersion and length of long single mode fiber is demonstrated using a novel asymmetrically modulated Sagnac interferometer. The mterferometer incorporates a phase modulator and a test fiber, so that dispersion and length can be determined from the interference fringe that is available at the Outut when a sweep RF signal is applied to the modulator. This technique measures dispersion with high temporal resolution, requires no fast test equipment and is suitable for installed fibers over a wide range of lengths.
