摘要

A remnant chromatic dispersion monitoring method based on spectral shift of a semiconductor optical amplifier is proposed for a high speed optical communication system with carrier suppressed return to zero format and single-channel speed of 40 Gbit/s. The monitoring performance can be optimized by carefully selecting the bandwidth and center wavelength of the optical filter. The dynamical monitoring range is +-60 ps/nm and the monitoring precision is about 5 ps/nm. This method is suitable for application in dynamical chromatic dispersion compensation of high speed optical communication systems.
