The IEEE 802.3ae* 2002 (10 Gigabit Ethernet standard) is different in some respects from earlier Ethernet standards in that it will only function over optical fiber, and only operates in fullduplex mode (collision-detection protocols are unnecessary ). IEEE 802.3u Fast Ethernet (100BASE-T) IEEE 802.3z Gigabit Ethernet (1000BASE-X) IEEE 802.3ab Gigabit Ethernet (1000BASE-T) IEEE 802.3ac Ethernet VLANs. The IEEE 802.3 Ethernet standard was established some time later. The docs below IEEE 802.3u standard clause 28 (for Fast Ethernet) IEEE standard 802.3z Standard clause 37 (for Gigabit Ethernet)". The original Ethernet Version 2 frame varies slightly from the 802.3 Ethernet frame Ethernet Standards. IEEE 802.3 half-duplex Ethernet (CSMA/CD)IEEE 802.3x full-duplex Ethernet - PAUSE frame. Technology improvements, and better interoperation of autonegotiation make it the preferred mode of operation, and is required on new technologies such as 1000BASE-T (802.3ab). Extension to 68Mhz spectrum and up to 500Mbps PHY rate. Gigabit ethernet doesn't even officially support anything but autonegotiation. "The IEEE 802.3 standard default is to run with autonegotiation enabled. IEEE1901 / HomePlug AV standard. The IEEE 802.3z defines the Gigabit Ethernet over fiber and cable, which has a physical media standard 1000Base-X (1000BaseSX - short wave covers up to 500m, and 1000BaseLX - long wave covers up to 5km). 1000base-T is the copper based version of the gigabit Ethernet standard defined by 802.3ab which, since it is over 6 months old, is available free of charge from the enlightened IEEE.
