A new technique is proposed and demonstrated for optical fibre chromatic dispersion measurement based on incoherent heterodyne interferometry, which was originally developed for characterising optical resonators. The free spectral range of the ring resonators containing a fibre under test is measured as a function of wavelength, from which group delay and chromatic dispersion can be estimated. As compared with the existing methods, the technique has the advantage of simple configuration and procedure.
