Unit 3 Assignment 1: Specifications - Definitions
4/10/14
Application
Describes cables, fire ratings and shielding
Unshielded Twisted Pair (UTP)
Types of Ethernet and phone cables twisted around each other to decrease interference from EMI. Has no shielding.
Shielded Twisted Pair (STP)
Same as the UTP cables except it is shielded in a metal sheath around it to stop external interference.
Fiber-Optic Cable
A cable that uses glass to transmit data using light waves.
Dark Fiber
Optical fiber that has already been laid but is not currently being used.
Coaxial Cable
A Cable that is commonly used in audio and video. It connects to cable television to televisions and also used in cable internet modems.
Plenum
The space between the ceiling and the drop ceiling or below the floor which can be used for air conditioning and running networking cables to connect the offices to the internet.
Riser
A space to allow the cables to pass between floors of a building.
Rip Cord
A strong string inside an optical cable used to strip the cable by pulling it so you don’t have to use a bladed tool.
Core
The center part of the fiber optic cable, it carries light.
Attenuation
Any reduction in the strength of a signal.
Noise
Any extraneous signal (electromagnetic energy) that interferes with the desired signal normally present in or passing through the system.
Headroom
The difference between the signal attenuation made by a wire or cable transmission medium, measured in decibels.
ANSI (American National Standards Institute)
Founded in 1918, a non-profit organization that creates standards for computers. To help enhance global competitiveness.
NFPA (National fire Protection Association)
Founded in 1896, non-profit organization that is dedicated to reduce the fire and other hazards life by making training, consensus codes and standards, education and research.
FCC (Federal Communication Commission)
Founded in 1934, regulates the electrical
