10GBASE-LR
IEEE 802.3ae specification for 10 Gigabit Ethernet over two strands of
9/125 micron core single-mode fiber cable.
10GBASE-SR
IEEE 802.3ae specification for 10 Gigabit Ethernet over two strands of
50/125 micron core multimode fiber cable.
10 Gigabit Ethernet
A 10 Gbps network communication system based on Ethernet.
Auto-Negotiation
Signalling method allowing each node to select its optimum operational
mode (e.g., speed and duplex mode) 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.
Collision Domain
Single CSMA/CD LAN segment.
CSMA/CD
CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the
communication method employed by Ethernet, Fast Ethernet, or Gigabit
Ethernet.
