WDM und DWDM

WDM – Wavelength Division Multiplex WDM wird auch als Wellenlängenmultiplex oder Wellenlängenvielfach bezeichnet. Jede Farbe des Lichtes wird einer bestimmten Frequenz der elektromagnetische Welle zugeordnet. Durch die Verwendung unterschiedlicher Farben (Frequenzen) lassen sich auf einem Lichtwellenleiter mehrere Datenkanäle unabhängig voneinander betreiben. Diese Methode entspricht dem Prinzip des Frequenzmultiplexverfahrens. Wobei die Wellenlänge mit der Frequenz vergleichbar […]

PON – Passive Optical Networks / Passive optische Netze

Ein passives optisches Netz ist ein Glasfasernetz, welches zur Signalverteilung ohne aktive Komponenten auskommt. Es arbeitet mit optischen Splittern, die über keine elektrischen Vermittlungsfunktionen verfügen. Passive optische Netze sind im Bereich zwischen Vermittlungsstelle und Teilnehmeranschluss für Gigabit-Glasfaseranschlüsse installiert. Sie funktionieren als Zugangsnetze für die Teilnehmer zum weltweiten Daten- und Kommunikationsnetz. Man unterscheidet zwischen passiven optischen […]
