This paper presents a chromatic dispersion monitoring technique using a clock‐frequency component for carrier‐suppressed return‐to‐zero (CSRZ) signal. The clock‐frequency component is extracted by a clock‐extraction (CE) process. To discover which CE methods are most efficient for dispersion monitoring, we evaluate the monitoring performance of each extracted clock signal. We also evaluate the monitoring ability to detect the optimum amount of dispersion compensation when optical nonlinearity exists, since it is more important in nonlinear transmission systems. We demonstrate efficient CE methods of CSRZ signal to monitor chromatic dispersion for optimum compensation in high‐speed optical communication systems.
