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.
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).
A cable terminated according to T568A on one end and T568B on the other is a crossover cable when used with the earlier twisted-pair Ethernet standards that use only two of the pairs because the pairs used happen to be pairs 2 and 3, the same pairs on which T568A and T568B differ. Crossover cables are occasionally needed for 10BASE-T and ...
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)
For many years during the mid to late 1980, this was the dominant Ethernet standard. Also called Thin Ethernet, Thinnet or Cheapernet. 10 Mbit/s over RG-58 coaxial cabling, bus topology with collision detection. Deprecated 2011. 10BROAD36: 802.3b-1985 (11) F: 1800 m @VF0.87 [10] 75 Ω coaxial An early standard supporting Ethernet over longer ...

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.
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 ...
