【Abstract】 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 bite-rate 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.更多还原
