Abstract
An optical communication system includes a first end terminal comprising a first transponder operable to receive a first electrical signal and generate an optical signal based at least in part on the first electrical signal for communication to a multiple span communication link. The optical signal experiences at least partial dispersion compensation from an optical dispersion compensating element as it traverses the communication link. The system also includes a second end terminal comprising a second transponder operable to receive the optical signal and generate a second electrical signal based at least in part on the optical signal. At least one of the first and second end terminals further includes an electronic dispersion compensation module operable to provide electronic dispersion compensation to at least a portion of at least one of the first and second electrical signals. The electronic dispersion compensation module is operable to at least partially compensate for at least a portion of a residual dispersion for which the optical dispersion compensating element does not compensate.
