10-Mbps baseband Ethernet specification using two pairs of twisted-pair cabling (Category 3, 4, or 5):
10Base-T
one pair for transmitting data and the other for receiving data. 10Base-T, 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
100-Mbps baseband Fast Ethernet specification using UTP wiring. Like the 10Base-T technology on
100Base-T
which it is based, 100Base-T sends link pulses over the network segment when no traffic is present.
However, these link pulses contain more information than those used in 10Base-T. The 100Base-T
specification is based on the IEEE 802.3 standard. See also 10Base-T,
IEEE
1000-Mbps Gigabit Ethernet specification using two strands of multimode or single mode fiber-optic
1000Base-LX/LH
cable per link. To guarantee proper signal recovery, a 1000Base-LX/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

IEEE
1000-Mbps Gigabit Ethernet specification using two strands of multimode fiber-optic cable per link.
1000Base-SX
To guarantee proper signal recovery, a 1000Base-SX link cannot exceed 1804 feet (550 meters) in
length. The 1000Base-SX specification is based on the IEEE 802.3 standard. See also
1000Base-LX/LH, 1000Base-ZX,
1000Base-T (GLC-T) SFP module connects a Cisco Gigabit Interface Converter (GBIC) port to
1000Base-T
Category 5 wiring via a standard RJ-45 interface. The maximum Category 5 wiring distance is 100 m.
The module provides with an option of connecting to a backhaul network interface.
1000-Mbps Gigabit Ethernet specification that refers to the 1000Base-CX, 1000Base-SX, and
1000Base-X
1000Base-LX standards for Gigabit Ethernet over fiber-optic cabling. The 1000Base-X specification is
based on the IEEE 802.3 standard. See also 1000Base-SX, 1000Base-LX/LH, 1000Base-ZX,
Ethernet, and
1000-Mbps Gigabit Ethernet specification using two strands of single mode fiber-optic cable per link.
1000Base-ZX
To guarantee proper signal recovery, a 1000Base-ZX link cannot be longer than 62.1 mi (100 km). This
is a Cisco specification. See also 1000Base-SX, 1000Base-LX/LH,
