Coaxial Cable Flashcards
What is the function of the inner conductor in coaxial cable?
It carries the data signals and is made of copper.
What material is the insulator in coaxial cable made from, and what is its purpose?
PVC plastic; it separates the inner conductor from the mesh conductor.
What is the braided mesh conductor made of, and what are its functions?
Aluminum or tin-coated copper; it serves as a second channel and as a ground.
What does the outer sheath of a coaxial cable do?
It protects the cable from external elements and is made of PVC plastic.
What are the advantages of coaxial cable over other types?
Less susceptible to EMI, resistant to physical damage, and has a large existing infrastructure.
What are the disadvantages of coaxial cable?
It’s expensive, not very flexible, and multiple splitters degrade signal quality.
What is the resistance rating of RG-59 and RG-6 cables?
75 ohms for both.
What is RG-59 coaxial cable typically used for?
CCTV video systems and short cable TV runs (< 3 meters
What are the primary uses of RG-6 cable?
Cable TV, satellite TV, and broadband internet.
Why is RG-6 preferred over RG-59 for coaxial implementations?
It carries higher-quality signals with much lower signal loss.
What is the BNC connector used for?
Legacy 10Base2 Ethernet, commercial video devices, and specialized industries
How is a BNC connector attached to coaxial cable?
It is molded onto the cable.
What is the F-Type connector used for?
Cable and satellite TV connections and cable modems for broadband.
How is an F-Type connector typically attached to coaxial cable?
It is crimped using a special tool (some twist-on types exist but may leak signal).
