The line encoding used by 10GBASE-T is the basis for the newer and slower 2.5GBASE-T and 5GBASE-T standard, implementing a 2.5 or 5.0 Gbit/s connection over existing category 5e or 6 cabling. [51] Cables that will not function reliably with 10GBASE-T may successfully operate with 2.5GBASE-T or 5GBASE-T if supported by both ends.
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 most popular variant, 1000BASE-T, is defined by the IEEE 802.3ab standard. It came into use in 1999, and has replaced Fast Ethernet in wired local networks due to its considerable speed improvement over Fast Ethernet, as well as its use of cables and equipment that are widely available, economical, and similar to previous standards.
Generally, layers are named by their specifications: [8] 10, 100, 1000, 10G, ... – the nominal, usable speed at the top of the physical layer (no suffix = megabit/s, G = gigabit/s), excluding line codes but including other physical layer overhead (preamble, SFD, IPG); some WAN PHYs (W) run at slightly reduced bitrates for compatibility reasons; encoded PHY sublayers usually run at higher ...
The IEEE 802.3ch-2020 2.5GBASE-T1, 5GBASE-T1, and 10GBASE-T1 standards are derived from the IEEE 802.3bp-2016 1000BASE-T1 Ethernet over single twisted pair standard, and share very little in common with the similarly named 2.5GBASE-T and 5GBASE-T standards at the PHY layer. 2.5GBASE-T1, 5GBASE-T1, and 10GBASE-T1 can run over a single twisted ...
coaxial cable connects machines together, each machine using a T-connector to connect to its NIC. Requires terminators at each end.

The autonegotiation specification was improved in the 1998 release of IEEE 802.3. This was followed by the release of the IEEE 802.3ab Gigabit Ethernet standard in 1999 which specified mandatory autonegotiation for 1000BASE-T. Autonegotiation is also mandatory for 1000BASE-TX and 10GBASE-T implementations. Currently, most network equipment ...
Moreover, this setup offers 15 to 25 times lower transceiver latency than current 10GBASE-T Cat 6/Cat 6A/Cat 7 cabling systems: 0.1 μs for Twinax with SFP+ versus 1.5 to 2.5 μs for current 10GBASE-T specification. The power draw of Twinax with SFP+ is around 0.1 watts, which is also much better than 4–8 watts for 10GBASE-T.
