What is 10 gigabit Ethernet

In computer networking, 10 gigabit Ethernet  refers to various technologies for transmitting Ethernet frames at a rate of 10 gigabits per second, first defined by the IEEE 802.3ae-2002 standard. Its adoption 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.

Like previous versions of Ethernet, 10GbE supports both copper and fiber cabling. However, due to its higher bandwidth requirements, higher-grade copper cables are required: category 6a or Class F/Category 7 cables for links up to 100m. Unlike previous Ethernet standards, 10 gigabit Ethernet defines only full duplex point-to-point links which are generally connected by network switches. Half duplex operation and hubs do not exist in 10GbE.
