Abstract:
Electronic dispersion compensation within optical communications using reconstruction. Within a communication system that includes any optical network portion, segment, or communication link, etc., that optical component/portion of the communication system is emulated within the electronic domain. For example, in a communication device having receiver functionality, deficiencies that may be incurred by the at least one optical portion of the communication system are compensated in the electronic domain of the communication device having the receiver functionality by employing reconstruction logic and/or circuitry therein. Multiple decision feedback equalizers (DFE) circuitries, implemented in the electronic domain, may be employed to provide feedback from different portions of the receiver functionality in accordance with performing compensation of optical incurred deficiencies (e.g., dispersion, non-linearity, inter-symbol interference (ISI), etc.). Within a communication device's receiver portion, equalization and compensation is performed in the electronic domain as adapted for high speed applications and higher order modulation schemes.
