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, with Time-division multiple access 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.
Major milestones:
The work on the 10G-EPON was continued by the IEEE P802.3bk Extended EPON Task Force, formed in March 2012. The major goals for this Task Force included adding support for PX30, PX40, PRX40, and PR40 power budget classes to both 1G-EPON and 10G-EPON. The 802.3bk amendment was approved by the IEEE-SA SB in August 2013 and published soon thereafter as the standard IEEE Std 802.3bk-2013. On 4 June 2020, the IEEE approved IEEE 802.3ca, which allows for symmetric or asymmetric operation with downstream speeds of 25 Gbit/s or 50 Gbit/s, and upstream speeds of 10 Gbit/s, 25 Gbit/s, or 50 Gbit/s over the same power-distance-splitter budgets.
Symmetric-rate 10/10G-EPON supports both transmit and receive data paths operating at 10 Gbit/s. The main driver for 10/10G-EPON was to provide adequate downstream and upstream bandwidth to support multi-family residential building (known in the standard as Multi Dwelling Unit or MDU) customers. When deployed in the MDU configuration, one EPON Optical Network Unit (ONU) may be connected to up to a thousand subscribers.
The 10/10G-EPON employs a number of functions that are common to other point-to-point Ethernet standards. For example, such functions as 64B/66B line coding, self-synchronizing scrambler, or gearbox are also used in optical fiber types of 10 Gigabit Ethernet links.
