What are the important parts of coaxial cable?
A coaxial cable consists of four basic parts:
- Inner conductor (center conductor)
- Outer conductor (shield)
- Dielectric, which separates the inner and outer conductors.
- Jacket, which is the outer polymer layer protecting the parts inside.
What is the importance of coaxial cable?
Coaxial cable is usually used by cable operators, telephone companies, and internet providers around the world. It enables conveying data, video, and voice communication to customers. It has also been used extensively within homes. It gives the advantages of reliable and accurate communication.
What cables and connectors does CATV use?
Coaxial cable (or “coax”) is the most common cable used for transmitting video signals. The name “coaxial” refers to the common axis of the two conductors….Choosing the correct cable.
| Analog TV | RG59/U | Acceptable performance on cable runs |
|---|---|---|
| DTV, CATV, SATV, MATV | RG6/U | Standard cable for these applications |
What is a type CATV cable used for?
A common type of 75 ohm coaxial cable is cable television (CATV) distribution coax, used to route cable television signals to and within homes. CATV distribution coax typically has a copper-clad steel (CCS) center conductor and a combination aluminum foil/aluminum braid shield, typically with low coverage (about 60%).
What is the most important measure of coax cabling?

What are CATV lines?
CATV is a shorthand term for cable television service. The cabling infrastructure that supports cable TV also supports cable internet. Many internet service providers (ISPs) offer customers cable internet service, television, and phone service over the same CATV lines.
What is the only important measure of coax cabling group of answer choices?
The Ohm rating for coaxial cabling is a relative measure of resistance (characteristic impedance) on the cable. What are the two basic types of twisted pair cabling? The two basic types of twisted pair cabling are shielded twisted pair (STP) and unshielded twisted pair (UTP).
What is the most common use of coaxial cable in networking today?
Typically, coaxial cable is used to carry voice, video, and data over the same wire. Two main types of coaxial cable are used in computer networking: thinnet (RG-58) and thicknet (RG-8 or RG-11). Thinnet cable can transmit 10Mbps up to 185 meters.
