摘　　要：A novel method for accurately measuring chromatic dispersion of optical fibers is proposed based on the use of chirped intensity-modulated signals.Unlike the conventional method,the proposed method utilizes the configurable transfer function of optical fibers caused by the residual chirp of intensity modulation,which not only eliminates the chirp error but also improves the measurement range through adjusting the chirp parameter of the intensity modulator.Our method is applicable for measuring both the magnitude and sign of chromatic dispersion of optical fibers or other dispersive devices at different operating wavelengths by using a vector network analyzer.
