A multi-bit packet carried on an optical network includes a marker pulse. A bit-rate clock for use in a bit-level operation on the packet is generated by replicating the marker pulse. The bit-level operation may comprise retiming, regeneration or demultiplexing. The marker pulse may be distinguished by a fixed, bit-asynchronous time relationship to the rest of the packet.
