10G-EPON

The 10 Gbit/s Ethernet Passive Optical Network standard, better known as 10G-EPON allows computer network connections over telecommunication provider infrastructure. The standard supports two configurations: symmetric, operating at 10 Gbit/s data rate in both directions, and asymmetric, operating at 10 Gbit/s in the downstream (provider to customer) direction and 1 Gbit/s in the upstream direction. It was ratified as IEEE 802.3av standard in 2009. EPON is a type of passive optical network, which is a point-to-multipoint network using passive fiber optic splitters rather than powered devices for fan-out from hub to customers.

EPON is a type of passive optical network, which is a point-to-multipoint network using passive fiber optic splitters rather than powered devices for fan-out from hub to customers. The Ethernet in the first mile task force of the Institute of Electrical and Electronics Engineers (IEEE) 802.3 standards committee published standards that included a passive optical network (PON) variant in 2004.In March 2006, the IEEE 802.3 held a call for interest for a 10 Gbit/s Ethernet PON study group. According to the CFI materials, representatives from the following companies supported the formation of the study group:Advance/Newhouse Communications, Aeluros, Agilent, Allied Telesyn, Alloptic, Ample Communications, Astar-ODSM, Broadcom, Centillium Communications, China Netcom, China Telecom, Chunghwa Telecom, Cisco Systems, ClariPhy Communications, Conexant Systems, Corecess, Corning, Delta Electronics, ETRI, Fiberxon, FOTEK Optoelectronics, ImmenStar, Infinera, ITRI, KDDI R&D Labs., K-Opticom, Korea Telecom, NEC, OpNext, Picolight, Quake Technologies, Salira Systems, Samsung Electronics, Softbank BB, Teknovus, Teranetics, Texas Instruments, Telecom Malaysia, TranSwitch, UNH-IOL, UTStarcom, Vitesse. By September 2006, IEEE 802.3 formed the 802.3av 10G-EPON Task Force to produce a draft standard. In September 2009, the IEEE 802 Plenary ratified an amendment to 802.3 to publish 802.3av amendment as the standard IEEE Std 802.3av-2009.
