Supermicro AOC-SGP-I2 dual-port Gigabit Ethernet NIC, a PCI Express ×4 card. 1000BASE-T (also known as IEEE 802.3ab) is a standard for Gigabit Ethernet over twisted-pair wiring. Each 1000BASE-T network segment is recommended to be a maximum length of 100 meters (330 feet), [5] [a] and must use Category 5 cable or better (including Cat 5e and ...

Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair. This led to the development of 10BASE-T and its successors 100BASE-TX, 1000BASE-T, 10GBASE-T and 40GBASE-T, supporting speeds of 10 and 100 megabit per second, then 1, 10 and 40 gigabit per second respectively.

The first generation of 100 Gigabit Ethernet using 10 and 25 Gbit/s lanes was standardized in June 2010 as IEEE 802.3ba alongside 40 Gigabit Ethernet. [20] The second generation using 50 Gbit/s lanes was developed by the IEEE 802.3cd task force along with 50 and 200 Gbit/s standards. [23]
Rates up to 100 Gigabit Ethernet were standardized in 2010 and 2011. [1] [2] [3] Ethernet's dominance is partly attributed to the simple advantages for the industry of adopting a single standard to drive up volumes and drive down prices.
The payload limit for jumbo frames is variable: while 9000 bytes is the most commonly used limit, smaller and larger limits exist. Many Gigabit Ethernet switches and Gigabit Ethernet network interface controllers and some Fast Ethernet switches and Fast Ethernet network interface cards can support jumbo frames. [2]
As of Dec 2022, 10GBASE-T network equipment is still substantially more expensive than 1GBASE-T, 2.5GBASE-T, and 5GBASE-T network equipment. IEEE 802.3bz also supports power over Ethernet, which had previously not been available with IEEE 802.3an 10GBASE-T. As early as 2013, the Intel Avoton server processors integrated 2.5 Gbit/s Ethernet ports.
Most manufacturers of active equipment and network cards have chosen to support the 8P8C for their 10 gigabit Ethernet products on copper and not the GG45, ARJ45, or TERA. [4] Therefore, the Category 6 specification was revised to Category 6 A to permit this use; products therefore require a Class E A channel (ie, Cat 6 A ).
