Fiber chromatic dispersion is a major limiting factor for ultrahigh bit-rate transmission in optical fiber communications, which restricts the transmission velocity and distance. Dynamical chromatic dispersion is an urgent problem needing to be solved for high biterate optical communication systems. Effective monitoring techniques are hearts of the dynamical compensation systems. Some dynamical monitoring techniques are discussed. Their mechanism, properties and performance are analyzed and compared.
