| 1000BASE-T |
A recent LAN standard for implementing 1000 Mbps Ethernet on Category 5 cable. See also Gigabit Ethernet.
|
| 100BASE-T |
The twisted pair version of 100 Mbps Ethernet.Requires Category 5 cabling.
|
| 10BASE2 |
Also called Thinnet.10 Mbps Ethernet on thin (RG58) coaxial cable.
|
| Attenuation |
The amount of signal lost as it travels through the cabling system.
|
| Backboard |
Refers to a plywood panel mounted on the wall of a telecom closet.Used to mount the cross connect.
|
| Backbone cabling |
Cabling between floors in a building or between buildings in a campus.
|
| Balun |
A transformer used to attach coaxial or twinaxial equipment to twisted pair cabling.
|
| BNC |
A bayonet style coaxial connector.
|
| Category 3 |
A performance classification for twisted pair cables, connectors and systems.Specified to 16 MHz.Suitable for voice and data applications up to 10 Mbps.
|
| Category 5 |
A performance classification for twisted pair cables, connectors and systems.Specified to 100 MHz.Suitable for voice and data applications up to 155 Mbps (possibly 1000 Mbps).
|
| Category 5e |
Also called Enhanced Category 5.A performance classification for twisted pair cables, connectors and systems.Specified to 100 MHz.Suitable for voice and data applications up to 1000 Mbps.
|
| Category 6 |
Also called Enhanced Category 5.A performance classification for twisted pair cables, connectors and systems.Specified to 100 MHz.Suitable for voice and data applications up to 1000 Mbps.
|
| Channel |
The entire horizontal cabling system. Everything between the computer and the LAN hub in the telecom closet, excluding the equipment connections.
|
| Coax |
Short for coaxial.Single-conductor cables with braided shields. Used in the 1980\'s for data transmission. Now generally replaced with UTP for data.Still used for video.
|
| Consolidation point |
An interconnect device that allows the horizontal cable to be split into two parts. Used for zone cabling.
|
| Cross connect (XC) |
Connecting hardware used to patch between two groups of cables (horizontal to backbone, for example). AMP 110Connect XC.
|
| Daily skew |
The difference in propagation delay between the slowest and fastest pairs in a cable or system.
|
| Data rate |
The speed, measured in bits per second, that a particular network (or other application) transmits data.
|
| dB |
Abbreviation for decibel. The logarithmic ratio of two powers, voltages or currents.
|
| Drop |
Refers to the horizontal cabling for one work area, as in "The job has 100 drops."
