10BaseT
10-Mbps baseband Ethernet specification using two pairs of twisted-pair cabling (Category 3, 4, or 5):
one pair for transmitting data and the other for receiving data. 10BaseT, which is part of the IEEE 802.3
specification, has a distance limit of approximately 328 feet (100 meters) per segment. See also IEEE
802.3 and Ethernet.
100BaseT
100-Mbps baseband Fast Ethernet specification using UTP wiring. Like the 10BaseT technology on
which it is based, 100BaseT sends link pulses over the network segment when no traffic is present.
However, these link pulses contain more information than those used in 10BaseT. The 100BaseT
specification is based on the IEEE 802.3 standard. See also 10BaseT, Fast Ethernet, and
IEEE 802.3.
1000BaseLX/LH
1000-Mbps gigabit Ethernet specification using two strands of multimode or single mode fiber-optic
cable per link. To guarantee proper signal recovery, a 1000BaseLX/LH link cannot exceed 1804 feet
(550 meters) in length over multimode fiber or 32,810 feet (10 km) in length over single mode fiber.
Based on the IEEE 802.3 standard with reach over single mode fiber extended from 5 km to 10 km. See
also 1000BaseSX, 1000BaseZX, Gigabit Ethernet, and
IEEE 802.3.
1000BaseSX
1000-Mbps gigabit Ethernet specification using two strands of multimode fiber-optic cable per link. To
guarantee proper signal recovery, a 1000BaseSX link cannot exceed 1804 feet (550 meters) in length.
The 1000Base SX specification is based on the IEEE 802.3 standard. See also 1000BaseLX/LH,
1000BaseZX, Gigabit Ethernet, and IEEE 802.3.
1000BaseX
1000-Mbps gigabit Ethernet specification that refers to the 1000BaseCX, 1000BaseSX, and
1000BaseLX standards for gigabit Ethernet over fiber-optic cabling. The 1000BaseX specification is
based on the IEEE 802.3 standard. See also 1000BaseSX, 1000BaseLX/LH, 1000BaseZX, Gigabit
Ethernet, and
IEEE 802.3.
1000BaseZX
1000-Mbps gigabit Ethernet specification using two strands of single mode fiber-optic cable per link.
To guarantee proper signal recovery, a 1000BaseZX link cannot be longer than 62.1 mi (100 km). This
is a Cisco specification. See also 1000BaseSX, 1000BaseLX/LH, Gigabit Ethernet, and IEEE 802.3.
802.x
A set of IEEE standards for the definition of LAN protocols.
