Abstract
This invention uses fiber characteristics combined with knowledge of the 8b10b code to discover and compensate for skew between parallel data streams, caused by chromatic dispersion, in a WDM system allowing the receiver to recover both the data and timing of the data streams as they were originally launched. This skew discovery and compensation does not require the insertion or deletion of any control symbols to/from the original 8b10b streams, and does not require the use of a training or sample sequence.
