Over the years the Institute of Electrical and Electronics Engineers (IEEE) 802.3 working group has published several standards relating to 10GbE.ġ0 Gbit/s Ethernet over fiber for LAN (10GBASE-SR, 10GBASE-LR, 10GBASE-ER, 10GBASE-LX4) and WAN (10GBASE-SW, 10GBASE-LW, 10GBASE-EW)ġ0GBASE-CX4 10 Gbit/s Ethernet over twinaxial cablingĪ revision of base standard incorporating 802.3ae, 802.3ak and errataġ0GBASE-T 10 Gbit/s Ethernet over copper twisted pair cableīackplane Ethernet, 1 and 10 Gbit/s over printed circuit boards (10GBASE-KR and 10GBASE-KX4)ġ0GBASE-LRM 10 Gbit/s Ethernet over multi-mode fiber with enhanced equalizationĪ revision of base standard incorporating the 802.3an/ap/aq/as amendments, two corrigenda and errata. As of 2012, although the price per gigabit of bandwidth for 10 Gigabit Ethernet was about one-third compared to Gigabit Ethernet, the price per port of 10 Gigabit Ethernet still hindered more widespread adoption. The adoption of 10 Gigabit Ethernet has been more gradual than previous revisions of Ethernet: in 2007, one million 10GbE ports were shipped, in 2009 two million ports were shipped, and in 2010 over three million ports were shipped, with an estimated nine million ports in 2011. Maximum distance over copper cable is 100 meters but because of its bandwidth requirements, higher-grade cables are required. Like previous versions of Ethernet, 10GbE can use either copper or fiber cabling. A networking device, such as a switch or a network interface controller may have different PHY types through pluggable PHY modules, such as those based on SFP+. The 10 Gigabit Ethernet standard encompasses a number of different physical layer (PHY) standards. The first standard for faster 100 Gigabit Ethernet links was approved in 2010. Unlike previous Ethernet standards, 10 Gigabit Ethernet defines only full-duplex point-to-point links which are generally connected by network switches shared-medium CSMA/CD operation has not been carried over from the previous generations Ethernet standards so half-duplex operation and repeater hubs do not exist in 10GbE. It was first defined by the IEEE 802.3ae-2002 standard. Router with 10 Gigabit Ethernet ports and three physical layer module typesġ0 Gigabit Ethernet ( 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second.
