We present a novel algorithm for reconstruction of the longitudinal distribution of zero-dispersion wavelength in an optical fiber from low power, end-to-end measurements of four-wave mixing efficiency. It is based on a modified version of the error-reduction approach used in classic phase-retrieval problems. Experimental results demonstrate the validity of this algorithm.
