摘要A novel measurement technique for the relative propagation delay of two signals based on a caliper ruler is proposed. The technique is applied to the chromatic dispersion measurements of single-mode fiber (SMF), dispersion-compensation fiber, and dispersion-shifted fiber. Compared to the conventional time-of-flight method, dispersion can be measured even when the delay difference is smaller than the measurement pulse¡̄s width. The sign of dispersion is preserved during measurement. The scheme also supports the usage of multiple wavelengths simultaneously for fast measurement. Measurement error of less than 0.2 ps̈M-km nm in SMF is experimentally demonstrated. © 2013 Optical Society of America.
