Experimental investigation of the modulation phase-shift method for the measure of the chromatic dispersion in a single-mode fiber coiled on a covered spool

Abstract

The measure of the chromatic dispersion of the optic fibers used in telecommunications networks and high-speed systems is very useful because it permits chromatic-dispersion compensators to be conceived across the wavelength range of interest. The modulation phase-shift method is used to measure chromatic dispersion in a standard single-mode fiber for telecommunication between 1200 and 1600 nm, by measuring the variation of the modulation phase of the transmitted signal modulated by a radio frequency signal, relative to the transmitted signal in a short reference fiber, modulated by the same signal. We verify the reduction of the thermal transitions in the measurement setup and fiber under test, while covering the spool of the fiber. © 2005 Wiley Periodicals, Inc.
