Abstract

A new method for the measurement of the group velocity dispersion (GVD) in optical fibers, based on optical frequency domain reflectometry (OFDR), is proposed and demonstrated. Frequency-chirped light is used as a light source, which allows the dispersion to be determined from changes in the frequency chirp rate. Accurate measurement of the average dispersion, at a single terminal, in fibers up to several tens of kilometers, is accomplished using a frequency-shifted feedback fiber laser as a light source.
