10 Gbit/s
10 Gigabit Ethernet defines a version of Ethernet with a nominal data rate of 10 Gbit/s, ten times as fast as Gigabit Ethernet. In 2002, the first 10 Gigabit Ethernet standard was published as IEEE Std 802.3ae-2002. Subsequent standards encompassed media types for single-mode fibre (long haul), multi-mode fibre (up to 300 m), copper backplane (up to 1 m) and copper twisted pair (up to 100 m). All 10 gigabit varieties were consolidated into IEEE Std 802.3-2008. As of 2009, 10 gigabit Ethernet is predominantly deployed in carrier networks, where 10GBASE-LR and 10GBASE-ER enjoy significant market shares.
| Name | Standard | Description |
|---|---|---|
| 10GBASE‑SR | 802.3ae | designed to support short distances over deployed multi-mode fiber cabling, it has a range of between 26 m and 82 m depending on cable type. It also supports 300 m operation over a new 2000 MHz·km multi-mode fiber. |
| 10GBASE‑LX4 | 802.3ae | uses wavelength division multiplexing to support ranges of between 240 m and 300 m over deployed multi-mode cabling. Also supports 10 km over single-mode fiber. |
| 10GBASE‑LR | 802.3ae | supports 10 km over single-mode fiber |
| 10GBASE‑ER | 802.3ae | supports 40 km over single-mode fiber |
| 10GBASE‑SW | 802.3ae | A variation of 10GBASE-SR using the WAN PHY, designed to interoperate with OC-192 / STM-64 SONET/SDH equipment |
| 10GBASE‑LW | 802.3ae | A variation of 10GBASE-LR using the WAN PHY, designed to interoperate with OC-192 / STM-64 SONET/SDH equipment |
| 10GBASE‑EW | 802.3ae | A variation of 10GBASE-ER using the WAN PHY, designed to interoperate with OC-192 / STM-64 SONET/SDH equipment |
| 10GBASE‑CX4 | 802.3ak | Designed to support short distances over copper cabling, it uses InfiniBand 4x connectors and CX4 cabling and allows a cable length of up to 15 m. Was specified by the IEEE Std 802.3an-2006 which has been incorporated into the IEEE Std 802.3-2008. |
| 10GBASE‑T | 802.3an | Uses unshielded twisted-pair wiring. |
| 10GBASE‑LRM | 802.3aq | Extend to 220 m over deployed 500 MHz·km multimode fiber |
| 10GBASE‑KX4 | 802.3ap | 1 m over 4 lanes of backplane |
| 10GBASE‑KR | 802.3ap | 1 m over a single lane of backplane |
