Abstract:
1. An optical packet synchronizer, comprising: packet detector circuitry configured to detect a plurality of optical packets; packet delay calculation circuitry configured to compare a periodic clock signal with the detected optical packets, wherein the periodic clock signal comprises a series of successive clock periods and the packet delay calculation circuitry is configured to calculate associated amounts of delay required to substantially align the plurality of optical packets with the series of successive clock periods of the periodic clock signal; an optical packet aligner configured to delay the plurality of optical packets by the associated amounts of delay calculated by the packet delay calculation circuitry; selection circuitry configured to select between multiple different clock signals associated with different outputs; and a parser unit configured to identify one of the outputs where the optical packets are directed and cause the selection circuitry to select one of the different clock signals associated with the identified one of the outputs as the periodic clock signal.
