Abstract

En node for et optisk, tidsdelt, multiplekset kommunikasjonssystem, oamt en fremgangsmåte for drift av en slik node, omtales. I utførelser av oppfinnelsen omfatter noden en multiplekser for å motta en rekke optiske signaler, og en kilde for optisk stråling, som kan være en kontinuerlig bølge-kilde eller en kilde for optiske pulser. Noden er innrettet slik at det utgående, tidsdelte og multipleksede optiske signalet består bare av optiske pulser fra kilden for optisk stråling.
