Electronic dispersion compensation system and method
The invention provides a system and method for an optical communication network to compensate impairments in the network to optimize system parameters, using electronic dispersion compensation (EDC) comprising a circuit for receiving two signals, representing amplitude and instantaneous frequency, and performing a full-field reconstruction of the signals. A dispersive transmission line circuit provides a coarse CD compensation of the reconstructed signals. An EDC circuit provides a fine impairment compensation of said reconstructed signals, and adaptively optimize system parameters. The system and method of the invention achieves low-cost long-distance transmission, up to 2000km, while maintaining the fast-adaptive compensation capability and provide a method for transparent long-haul and metro-optical networks.
