10G EPON
This subcommittee congratulates the ratification of IEEE Std. 802.3avTM-2009 10G EPON specifications by IEEE P802.3av Task Force with efforts to extend the speed of EPON networks to 10Gb/s. This 10G-EPON standard supports symmetric and asymmetric line-rate operations. The symmetric option operates at 10 Gb/s in both the downstream and upstream directions. The asymmetric option, which reflects the fact that IP video services create bandwidth pressure mostly in the downstream direction, uses 10 Gb/s downstream and 1 Gb/s upstream.
IEEE Std. 802.3ah 1 Gb/s EPON (1G-EPON) systems have been deployed to more than 30 million subscribers worldwide and support diverse services, including IPTV, VoIP, and cellular backhaul. Given the large and accelerating deployment of 1G-EPON systems, the IEEE Std. 802.3av enables seamless upgrades via the simultaneous operation of 1 Gb/s and 10 Gb/s symmetric and asymmetric EPON systems on the same outside plant. This allows operators to introduce 10G-EPON without replacing any existing 1G-EPON customer equipment and minimizes the operational impact of upgrading a large, in-service FTTH network.
Currently there are many 10G EPON field trial under way primarily in the APAC regions and initial deployments of the 10G-EPON equipment are expected in 2010.
White Papers
Overview of 10Gb/s EPON Status, Requirements and Applications - May 09
The wide adoption of 1G Ethernet passive optical networks (EPON) (per IEEE std P802.3ahTM) provided a significant jump in access network capacity and created demand for greater bandwidth-intensive applications and services such as Internet Protocol Television (IPTV), Video-on-Demand (VoD) and high-grade internet protocol (IP) telephony known as Voice over IP (VoIP). To address these market demands, the IEEE P802.3av Task Force was created in September 2006 and its 10G-EPON draft builds upon the compatibility with the existing 1GEPON.
Provider Backbone Transport Overview - Dec. 07
This paper discusses a new technology called Provider Backbone Transport (PBT) which can be employed within the service provider domain of a Provider Backbone Bridged Network (PBBN) to allow configuration of resilient, traffic engineered, SLA driven, point-to-point Ethernet trunks facilitating guaranteed QoS.
Ethernet Provides the Solution for Broadband Subscriber Access - April 06
Overcoming the obstacle of the last mile - the connection between an Internet service provider and a business or home - has been the elusive, final frontier. Ethernet has emerged as the frontrunner for transporting broadband Internet protocol transmissions.
Ethernet - The Next Generation WAN Transport Technology - May 02
The LAN, MAN, and WAN are now united under a single medium, Ethernet. This paper describes the technical details, and explains how carriers can now take advantage of Ethernet as a transport for their network backbone and their service media.
10 Gigabit Ethernet Interconnection with Wide Area Networks - Mar. 02
With the advent of 10 Gigabit Ethernet, the commonality of line rates between OC-192 SONET and 10GE has opened up the opportunity to simplify the interface. This paper describes how 10GE nodes can easily interconnect with OC192 SONET networks without leaving the Ethernet cost model behind.
