Question

In coaxial cable the material used as space is

• A. teflon (or) polyethylene
• B. glass or mica
• C. a gaseous medium
• D. glass
• E. mica

Answer 1

The correct option is A

teflon (or) polyethylene

Coaxial cable:

1. Coaxial cable is now used much less in computer networks due to the development of contemporary UTP (Unshielded Twisted Pair) and STP (Shielded twisted pair) twisted pair lines, although it still plays a significant role in analogue systems like cable television distribution networks.
2. The fundamental components of a coaxial cable are a center conductor encased in insulation, a concentric shielding that is uniformly spaced from the center, and an outer jacket made of rubber for environmental protection.
3. Dual shielded coaxial cable has one layer of foil insulation and one layer of braided metal shielding; quad shielded coaxial cable has two layers of foil insulation and two layers of braided metal shielding.

Material used as space in coaxial cable:

1. It is a type of copper cable specially constructed with a metal shield and other elements engineered to block signal interference.
2. The electrical cable consists of a round conducting wire which surrounded by an insulating spacer.
3. An additional cylindrical conducting shield is positioned around the insulating spacer.
4. In most cases, the insulating spacers are constructed from durable solid polymers like Teflon or polyethylene.

Hence, option $\mathrm{A}$ is the correct answer.
