The IEEE 802.3 working group is concerned with the maintenance and extension of the Ethernet data communications standard. Additions to the 802.3 standard [91] are performed by task forces which are designated by one or two letters. For example, the 802.3z task force drafted the original Gigabit Ethernet standard.
The figures below are simplex data rates, which may conflict with the duplex rates vendors sometimes use in promotional materials. Where two values are listed, the first value is the downstream rate and the second value is the upstream rate. The use of decimal prefixes is standard in data communications.
Max frame size extended to 1522 bytes (to allow "Q-tag"). The Q-tag includes 802.1Q VLAN information and 802.1p priority information. 802.3ad: 2000-03 Link aggregation for parallel links, since moved to IEEE 802.1AX: 802.3-2002 2002-01 (802.3ag) A revision of the base standard incorporating the three prior amendments and errata 802.3ae: 2002-06
A standardized variant of 10 Gigabit Ethernet, called WAN PHY, is designed to inter-operate with OC-192 transport equipment while the common version of 10 Gigabit Ethernet is called LAN PHY (which is not compatible with OC-192 transport equipment in its native form). The naming is somewhat misleading, because both variants can be used on a wide ...
The size of the payload of non-standard jumbo frames, typically ~9000 Bytes long, collides with the range used by EtherType, and cannot be used for indicating the length of such a frame. The proposition to resolve this conflict was to substitute the special EtherType value 0x8870 when a length would otherwise be used. [ 2 ]
The QSFP14 standard is designed to carry FDR InfiniBand, SAS-3 [54] or 16G Fibre Channel. 100 Gbit/s (QSFP28) The QSFP28 standard [7] is designed to carry 100 Gigabit Ethernet, EDR InfiniBand, or 32G Fibre Channel. Sometimes this transceiver type is also referred to as QSFP100 or 100G QSFP [55] for sake of simplicity. 200 Gbit/s (QSFP56)

In computer networking, Gigabit Ethernet (GbE or 1 GigE) is the term applied to transmitting Ethernet frames at a rate of a gigabit per second. The most popular variant, 1000BASE-T , is defined by the IEEE 802.3ab standard.
