CA 2190970

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.

Un paquet à plusieurs bits véhiculé sur un réseau optique comprend une impulsion de marquage. Un signal de synchronisation de débit binaire, utilisé dans une opération au niveau du bit appliquée sur le paquet, est produit par reproduction de l'impulsion de marquage. L'opération au niveau du bit peut comprendre les opérations de resynchronisation, régénération ou démultiplexage. La distinction entre l'impulsion de marquage et les autres impulsions du paquet s'effectue au moyen d'une relation temporelle, fixe et asynchrone au niveau du bit établie entre ces impulsions.
