10 Gbit/s Datendurchsatz mit DOCSIS 3.1 Distributed CCAP Nodes

Mit der Remote MAC-PHY Topologie entfällt die Notwendigkeit für CMTS / CCAP-Systeme in der Kabelkopfstelle

(PresseBox) (Friedberg, )
DEV Systemtechnik (www.dev-systemtechnik.com) führt eine Reihe von Distributed CCAP Lösungen für den europäischen Kabelnetzmarkt ein. Die DOCSIS 3.1-kompatiblen Access Nodes verfügen über eine vollständige CMTS-Einheit.

Der nächste große Schritt in der Entwicklung von DOCSIS-Netzwerken ist die Implementierung von Distributed Access Architecture (DAA) Topologien. Damit lassen sich – im Vergleich zu Lösungen, die auf herkömmliche CMTS / CCAP Kopfstellen setzen – die Kapazität erhöhen und die Kosten reduzieren.

Basierend auf der Remote-PHY Topologie, die nur die Signalerzeugung (den PHY-Layer) in den Zugriffsknoten verschiebt, wird im Remote MAC-PHY Ansatz sowohl der PHY-Layer als auch die DOCSIS-Verarbeitung (MAC-Layer) in die Access Node verlagert.
