10Base2

An IEEE 802.3 specification for Ethernet at 10Mbps over thin coaxial cable. The maximum length of a 10Base2 segment is 185 meters (that is, 607 feet). 10Base2 operates at 10Mbps and uses a baseband transmission method.



10Base5

The IEEE 802.3 specification for 10Mbps Ethernet using thick coaxial cable. The maximum length of a 10Base5 segment is 500 meters (that is, 1,640 feet).



10BaseFL

The IEEE 802.3 specification for running Ethernet at 10Mbps over fiber optic cable. The maximum length of a 10BaseFL segment is 2,000 meters (6,561 feet).



10BaseT

The IEEE 802.3i specification for running Ethernet at 10Mbps over twisted-pair cabling. The maximum length of a 10BaseT segment is 100 meters (that is, 330 feet).



100BaseFX

The IEEE 802.3 specification for running Fast Ethernet at 100Mbps over fiber-optic cable. The maximum length of a 100BaseFX segment is 2,000 meters (6,561 feet), in full duplex mode.



100BaseT

The IEEE 802.3 specification for running Ethernet at 100Mbps over twisted-pair cabling. The maximum length of a 100BaseT segment is 100 meters (that is, 330 feet).



100BaseT4

The IEEE specification that allows the use of Fast Ethernet (100Mbps) technology over existing Category 3 and Category 4 wiring, using all four pairs of wires. The maximum length of a 100BaseT4 segment is 100 meters (that is, 330 feet).



100BaseTX

An IEEE 802.3u specification, also known as Fast Ethernet, for running Ethernet at 100Mbps over STP or UTP. The maximum length of a 100BaseTX segment is 100 meters (that is, 330 feet).



100BaseVG-AnyLAN

The IEEE 802.12 specification that allows data transmissions of 100Mbps over Category 3 cable, using all sets of wires. VG in 100BaseVG-AnyLAN stands for voice grade because of its capability to be used over voice-grade cable. The maximum length of a 100BaseVG-AnyLAN segment is 100 meters (330 feet) on Category 3 cable, 150 meters (492 feet) on Category 5 cable, and 2,000 meters (6,561 feet) on fiber-optic cable.



1000BaseT

IEEE 802.3ab standard that specifies Gigabit Ethernet over Category 5 UTP cable. The standard allows for full-duplex transmission using the four pairs of twisted cable



1000BaseX

The IEEE 802.3z specification, also known as Gigabit Ethernet, that defines standards for data transmissions of 1000Mbps (1Gbps). 1000Basex is most often associated with fiber or STP cable. 1000BaseX refers collectively to three distinct standards: 1000BaseLX, 1000BaseSX, and 1000BaseCX.



1000BaseCX

IEEE802.3ab standard that uses a special shielded copper cable. 1000BaseCX can be used up to a maximum distance of 25 meters.



1000BaseLX

IEEE 802.3z standard that specifies Gigabit Ethernet over fiber-optic cable. 1000BaseLX can be used up to 5,000 meters.



1000BaseSX

IEEE 802.3z standard that specifies Gigabit Ethernet over fiber-optic cable.



10GbE

Term commonly used to refer to the 10Gbps Ethernet networking standards such as 10GBaseER, 10GBaseLR, and 10GBaseSR. 10 Gigabit Ethernet is defined in the IEEE 802.3ae standard



10GBaseER

10Gbps Ethernet networking standard that can be used up to 40,000 meters.



10GBaseLR

10Gbps Ethernet networking standard that can be used up to 10,000 meters. 10GBaseLR uses single-mode fiber-optic cabling.



10GBaseSR

10Gbps Ethernet networking standard that can be used over relatively short distances, up to 300 meters.
