A copper based cable that consists of one or more insulated twisted pair wires encased in a plastic sheath
What is a Shielded Twisted Pair (STP)?
A copper based cable containing twisted pair wires that are individually insulated and surrounded by a shielding made of a metallic substance such as foil
What is a Fiber Optic Cable?
A form of cable that contains one or several glass or plastic fibers in its core that it uses to transmit light via a pulsing light sent from a laser or LED
What are the two types of Fiber Optic Cable?
Single Mode Fiber (SMF) & Multimode Fiber (MMF)
What is the difference between copper based cables and fiber optic cables?
Fiber Optic transmits data via a pulsing light, while a copper based cable transmits data via electric signals
What does the Backbone consist of?
The cables or wireless links that provide interconnection between the entrance facility and the MDF and between the MDF and the IDFs.
In large modern networks what do backbones typically consist of?
Fiber Optic Cables
When terminating twisted pair, cabling do not leave more than ____ of exposed cablebefore a twisted pair termination
1in.
Define Crosstalk
Interference between wires
Define Bend Radius
The radius of the maximum arc into which you can loop a cable without impairing data transmission
What is the general bend radius of a twisted pair cable
Equal to or greater than four times the diameter of the cable
What is EMI?
A type of interference that can be caused by motors, power lines, televisions, copiers, fluorescent lights, or other types of electrical activity.
What is one way to avoid EMI?
To install cable at least 3ft away from anything that may cause EMI
Where is the plenum located?
The area above the ceiling tile or below the subflooring
What makes a cable sheath plenum rated?
It is coated with a flame resistent jacket that produces less smoke than regular cable that is coated with PVC
