subject: The Basics of Passive Optical Networking [print this page] IEEE 802.3av - 10G-EPON (10 Gigabit Ethernet PON) is an IEEE Task Force for 10Gbit/s, backward compatible with 802.3ah EPON. 10GEPON will use separate wavelengths for 10G and 1G downstream. 802.3av will continue to use a single wavelength for both 10G and 1G upstream with TDMA separation.
