Abstract
Systems and methods for the relative phase measurement and alignment of 66B encoded signals include receiving a plurality of 66B encoded signals each comprising sync headers which are periodically converted, determining a phase of each of the plurality of 66B encoded signals based on the periodically converted sync headers, and aligning the phase of each of the plurality of 66B encoded signals based on the determining. The periodically converted sync headers can include changing one of a first bit and a second bit of the sync header. A period of the periodically converted sync header can be set at twice a phase difference which is compensated at an egress point of the plurality of 66B encoded signals.
