Description

Amendment Standard – Superseded. This amendment to IEEE Std 802.3-2002 as amended by IEEE Std 802.3ae-2002, IEEE Std 802.3af-2003, IEEE Std 802.3aj-2003, and IEEE Std 802.3ak-2004 combines a minimal set of extensions to the IEEE 802.3 Media Access Control (MAC) and MAC Control sublayers with a family of Physical (PHY) Layers. These Physical Layers include optical fiber and voice grade copper cable Physical Medium Dependent sublayers (PMDs) for point-to-point connections in subscriber access networks. This amendment also introduces the concept of Ethernet Passive Optical Networks (EPONs), in which a point to multi-point (P2MP) network topology is implemented with passive optical splitters, along with optical fiber PMDs that support this topology. In addition, a mechanism for network Operations, Administration and Maintenance (OAM) is included to facilitate network operation and troubleshooting. To support these innovations, options for unidirectional transmission of frames are provided for 100BASE-X, 1000BASE-X, 10GBASE-R, 10GBASE-W, and 10GBASE-X.
