1. A communications device comprising:
- an Optical domain Adaptive Dispersion Compensation Module (OADCM) operable to provide a first dispersion compensation to a received signal, the received signal having a plurality of wavelengths;
an Electrical domain Adaptive Distortion Compensation Module (EADCM) coupled to the OADCM and operable to provide a second dispersion compensation to the received signal; and
a controller coupled to both the OADCM and the EADCM, the controller operable to selectively control a level of the first and the second dispersion compensation to be applied to the received signal, where the controller controls the EADCM based on feed forward information provided to the controller from the OADCM.

12. A method comprising:
-
i) measuring signal distortion of an electrical signal having a plurality of channels; ii) processing the signal distortion measurements to produce at least one control value for one of an optical domain adaptive dispersion compensation module (“
OADCM”
) or an electrical domain adaptive distortion compensation module (“
EADCM”
); andiii) selectively applying the at least one control value to the EADCM to provide dispersion compensation to the optical signal, using feed forward information provided to the controller from the OADCM. - View Dependent Claims (13, 14, 15)
