Abstract

Et optisk nettverk innbefatter et antall noder koblet til et optisk overføringsmedium, slik som en optisk fiberbuss. Hver av nodene innbefatter en mørkpuls-generator. Forskjellige noder mater ut mørke pulser i forskjellige tidsluker på overføringsmediet for å danne et OTDM-signal med mørke pulser. Nettet kan ha en flerbruker-busstopologi.
