10BASE-T
IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5
UTP cable.
100BASE-FX
IEEE 802.3u specification for 100 Mbps Fast Ethernet over two strands of 50/125 or
62.5/125 micron core fiber cable.
100BASE-TX
IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5
UTP cable.
1000BASE-LH
Long haul Gigabit Ethernet over two strands of 9/125 micron core fiber cable.
1000BASE-LX
IEEE 802.3z specification for Gigabit Ethernet over two strands of 9/125 micron core
fiber cable.
1000BASE-SX
IEEE 802.3z specification for Gigabit Ethernet over two strands of 50/125 or 62.5/
125 micron core fiber cable.
1000BASE-T
IEEE 802.3ab specification for Gigabit Ethernet over two pairs of Category 5, 5e, or
better 100-ohm UTP cable.
Auto-Negotiation
Signalling method allowing each node to select its optimum operational mode
(speed and duplex) based on the capabilities of the node to which it is connected.
Bandwidth
The difference between the highest and lowest frequencies available for network
signals. Also synonymous with wire speed, the actual speed of the data
transmission along the cable.
Collision
A condition in which packets transmitted over the cable interfere with each other.
Their interference makes both signals unintelligible.
