Ethernet defined a number of IEEE (Institute of Electrical and Electronics Engineers) 802.3 standards. These standards define the physical and data-link layer specifications for Ethernet. Some most important 802.3 standards are:
10Base-T (IEEE 802.3) – 10 Mbps with category 3 unshielded twisted pair (UTP) wiring, up to 100 meters long.
100Base-TX (IEEE 802.3u) – Known as Fast Ethernet, uses category 5, 5E, or 6 UTP wiring, up to 100 meters long.
100Base-FX (IEEE 802.3u) – Version of Fast Ethernet that uses multi-mode optical fiber. Up to 412 meters long.
1000Base-CX (IEEE 802.3z) – Uses copper twisted-pair cabling. Up to 25 meters long.
1000Base-T (IEEE 802.3ab) – Gigabit Ethernet that uses Category 5 UTP wiring. Up to 100 meters long.
1000Base-SX (IEEE 802.3z) – 1 Gigabit Ethernet running over multimode fiber-optic cable.
1000Base-LX (IEEE 802.3z) – 1 Gigabit Ethernet running over single-mode fiber.
10GBase-T (802.3.an) – 10 Gbps connections over category 5e, 6, and 7 UTP cables.
10Base-T (IEEE 802.3) – 10 Mbps with category 3 unshielded twisted pair (UTP) wiring, up to 100 meters long.
100Base-TX (IEEE 802.3u) – Known as Fast Ethernet, uses category 5, 5E, or 6 UTP wiring, up to 100 meters long.
100Base-FX (IEEE 802.3u) – Version of Fast Ethernet that uses multi-mode optical fiber. Up to 412 meters long.
1000Base-CX (IEEE 802.3z) – Uses copper twisted-pair cabling. Up to 25 meters long.
1000Base-T (IEEE 802.3ab) – Gigabit Ethernet that uses Category 5 UTP wiring. Up to 100 meters long.
1000Base-SX (IEEE 802.3z) – 1 Gigabit Ethernet running over multimode fiber-optic cable.
1000Base-LX (IEEE 802.3z) – 1 Gigabit Ethernet running over single-mode fiber.
10GBase-T (802.3.an) – 10 Gbps connections over category 5e, 6, and 7 UTP cables.
