10GBASE-T
10GBASE-T, or
IEEE 802.3an-2006, is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded
twisted pair cables, over distances up to 100 metres (330 ft).10GBASE-T cable infrastructure can also be used for 1000BASE-T allowing a gradual upgrade from 1000BASE-T using autonegotiation to select which speed to use. 10GBASE-T has higher latency and consumes more power than other 10 gigabit Ethernet physical layers. As of 2008 10GBASE-T silicon is available from several manufacturers with claimed power dissipation of 6 W and a latency approaching 1 microsecond
Connectors
10GBASE-T uses the IEC 60603-7 8P8C (commonly known as RJ45) connectors already widely used with Ethernet. Transmission characteristics are now specified to 500 MHz.
Cables
Category 6A or better balanced twisted pair cables specified in ISO 11801 amendment 2 or ANSI/TIA-568-C.2 are needed to carry 10GBASE-T up to distances of 100 m.
Category 6 cables can carry 10GBASE-T for shorter distances when qualified according to the guidelines in ISO TR 24750 or TIA-155-A.
