A Simple Method for Chromatic Dispersion Measurement Using Sagnac Interferometer with Mach-Zehnder Modulator

In this paper we propose the simple system for measuring the chromatic dispersion of a fiber by using Sagnac interferometer with a Mach-Zehnder modulator and induce the equivalent model and the transfer function of this system. The chromatic dispersion of fibers with length of 2.235km is measured by using this method in wavelength region from 1500nm to 1580nm and we conform that the measured results had a good agreement with the theoretical results given Corning Fiber.
