802.3ae is an IEEE 10-Gigabit Ethernet standard, which offers data speeds up to 10 billion bits per second but preserves similar benefits to those of the preceding Ethernet standard. 10-Gigabit Ethernet is used to interconnect local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs). 10-Gigabit Ethernet uses the familiar IEEE 802.3 Ethernet media to access control (MAC) protocol and its frame format and size. However, it supports the full duplex mode but not the half-duplex operation mode, and it only functions over optical fiber. So it does not need the carrier-sensing multiple-access with Collision Detection (CSMA/CD) protocol as it is used in other Ethernet standards.
