Abstract
In an earlier work, we proposed the chromatic dispersion monitoring technique of
non-return to zero (NRZ) signal based on clock-frequency component (CFC) through numerical
simulations. However, we have not yet shown any experimental demonstration or analytic derivation of
it. In this paper, we show an experimental demonstration and analytic derivation of the proposed
chromatic dispersion monitoring technique. We confirm that the experimental results and the analytic
results correspond with the simulation results. We also demonstrate that monitoring range and
accuracy can be improved by using a simple clock-extraction method.
