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.

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 asymmetric 10/1G-EPON appear less challenging than the symmetric option, as this specification relies on fairly mature technologies. The upstream transmission is identical to that of the 1G-EPON (as specified in IEEE standard 802.3ah), using deployed burst-mode optical transceivers. The downstream transmission, which uses continuous-mode optics, will rely on the maturity of 10 Gbit/s point-to-point Ethernet devices.
