What are the main types of network cables?

• Ethernet cables

• Twisted pair cables, coaxial cables, fiber optic cables

• USB cables

• HDMI cables

What is the maximum length for a standard Ethernet cable?

• 150 meters

• 100 meters

• 50 meters

• 200 meters

Describe the structure of a twisted pair cable.

• A twisted pair cable is designed to transmit power rather than data.

• A twisted pair cable is made of fiber optic strands bundled together.

• A twisted pair cable is made up of pairs of insulated copper wires twisted together, designed to reduce interference and improve signal quality.

• A twisted pair cable consists of a single copper wire surrounded by plastic insulation.

What are the two categories of twisted pair cables?

• Twisted Pair and Parallel Pair

• Single Twisted Pair and Double Twisted Pair

• Coaxial Cable and Fiber Optic Cable

• Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP)

What is the primary use of coaxial cables?

• Transmitting cable television signals and internet data.

• Transmitting audio signals only

• Powering electrical devices

• Storing data in computers

How does fiber optic cable transmit data?

• Using electrical signals through copper wires.

• Utilizing sound waves through air.

• Fiber optic cable transmits data using light signals through total internal reflection.

• Transmitting data via radio waves.

What are the advantages of using fiber optic cables over copper cables?

• Better durability in harsh environments

• Easier installation process than fiber optics

• Lower cost compared to fiber optics

• Advantages of fiber optic cables over copper cables include higher bandwidth, faster speeds, reduced electromagnetic interference, longer transmission distances, and lighter weight.

What is the maximum length limitation for fiber optic cables?

• Up to 10 kilometers for single-mode fibers; 1 kilometer for multi-mode fibers.

• Up to 200 kilometers for single-mode fibers; 500 meters for multi-mode fibers.

• Up to 50 kilometers for single-mode fibers; 100 meters for multi-mode fibers.

• Up to 100 kilometers for single-mode fibers; 300 to 400 meters for multi-mode fibers.

Explain the concept of cable shielding.

• Cable shielding is the use of a conductive layer around cables to protect against electromagnetic and radio frequency interference.

• Cable shielding is a method of increasing cable length.

• Cable shielding refers to the insulation of cables to prevent physical damage.

• Cable shielding is the process of connecting cables to a power source.

What are the different types of shielding techniques used in cables?

• Rubber insulation

• Copper grounding

• Plastic casing

• Twisted pair shielding, foil shielding, braided shielding, overall shielding
