Die ITU-T (International Telecommunication Union-Telecommunication Standardization Sector) hat gegeben\u00a0Genehmigung der ersten Stufe<\/a>\u00a0zu Standards, die die PON-Technologie (Passive Optical Network) anheben werden\u00a0neue Durchsatzniveaus<\/a>. Die G-989-Standardreihe definiert die Eigenschaften von NG-PON2-Implementierungen (Next-Generation Passive Optical Network Stage 2), die \u201eFiber-to-the-Home\u201c- oder \u201eFiber-to-the-Premises\u201c-Datenraten erm\u00f6glichen erreichen bis zu 40 Gbit\/s. Dies geht weit \u00fcber die M\u00f6glichkeiten der aktuellen PON-Technologie hinaus. Die ITU-T betrachtet NG-PON2 als Nachfolger von GPON (Gigabyte-f\u00e4higes PON), das Raten von 2,488 Gbit\/s im Downstream und 1,244 Gbit\/s im Upstream erreichen kann, und 10G-PON (auch XG-PON1 genannt), das dazu in der Lage ist 10 Gbit\/s Downstream und 2,5 oder 5 Gbit\/s Upstream. NG-PON2 basiert auf einer Punkt-zu-Mehrpunkt-Architektur mit mehreren Wellenl\u00e4ngen. Es nutzt Zeit- und Wellenl\u00e4ngenmultiplex (TWDM) in Verbindung mit abstimmbaren optischen Transceivern, um eine maximale Downstream-Zugriffsrate von 10 Gbit\/s f\u00fcr jede Wellenl\u00e4nge bereitzustellen. Typischerweise werden in beiden Richtungen vier bis acht Wellenl\u00e4ngen verwendet. Ein einzelnes Optical Line Terminal (OLT) in der Zentrale eines Anbieters kann \u00fcber einen optischen Splitter bis zu 256 Optical Network Units (ONUs) am Standort des Kunden versorgen. Ein gro\u00dfer Vorteil des neuen Standards besteht darin, dass NG-PON2 bestehende optische Verteilungsnetze, die urspr\u00fcnglich f\u00fcr GPON oder XG-PON1 entwickelt wurden, wiederverwenden kann. Dar\u00fcber hinaus erm\u00f6glicht der NG-PON2-Wellenl\u00e4ngenplan die Koexistenz mit diesen fr\u00fcheren Technologien auf demselben System. Gro\u00dfe Dienstleister, darunter Verizon, Energia und Vodafone, haben bereits Feldversuche mit NG-PON2 durchgef\u00fchrt. Im Rahmen des Verizon-Tests gelang es, FiOS-Breitband mit Geschwindigkeiten von mehr als 10 Gbit\/s bis zum Haus eines Kunden drei Meilen von der Zentrale entfernt bereitzustellen. Die ITU-T betrachtet NG-PON2 als \u201eeinen wichtigen Meilenstein im Bereich der Zugangsvernetzung\u201c.
