Abstract
A system for measuring chromatic dispersion in an optical fiber includes a multimode laser diode adapted to generate an optical pulse through gain switching; a highly dispersive optical fiber adapted to allow the optical output pulse to pass therethrough, and then adapted to separate each mode of the multimode laser diode to generate a reference signal; a test optical fiber adapted to allow an optical pulse for each wavelength separated by the highly dispersive optical fiber to pass therethrough to vary a repetition rate of the optical pulse train due to a chromatic dispersion characteristic of the test optical fiber using the optical pulse as the reference signal; and a high speed photodetector and RF spectrum analyzer adapted to detect eh variation of the repetition rate of the optical pulse train due to the chromatic dispersion characteristic of the test optical fiber.
