Understanding Cable Types

What are the main types of twisted pair cables?

• Fiber optic cable

• Single-core cable

• Coaxial cable

• The main types of twisted pair cables are unshielded twisted pair (UTP) and shielded twisted pair (STP).

What is the difference between STP and UTP cables?

• UTP cables are used for fiber optic connections.

• STP cables are more flexible than UTP cables.

• STP cables have shielding for interference protection, while UTP cables do not.

• STP cables are faster than UTP cables.

What are the advantages of coaxial cables over twisted pair cables?

• Coaxial cables offer better resistance to interference, higher bandwidth, longer distances, and greater durability.

• Twisted pair cables have better durability than coaxial cables.

• Coaxial cables are lighter than twisted pair cables.

• Coaxial cables are more flexible than twisted pair cables.

In what applications are fiber optic cables typically used?

• Bluetooth devices

• Telecommunications, internet connections, cable television, medical instruments, industrial applications.

• Household wiring

• Solar panel connections

What is the maximum distance for effective signal transmission in twisted pair cables?

• 100 meters

• 300 meters

• 200 meters

• 50 meters

How does the bandwidth of fiber optic cables compare to coaxial cables?

• Coaxial cables have a higher bandwidth than fiber optic cables.

• Fiber optic cables have a higher bandwidth than coaxial cables.

• Fiber optic cables and coaxial cables have the same bandwidth.

• Fiber optic cables have a lower bandwidth than coaxial cables.

What are the key components of a coaxial cable?

• Fiber optic core, plastic casing, copper wire, external cover

• Twisted pair wires, foam insulation, metal casing, outer sheath

• Single conductor, rubber insulation, aluminum shield, plastic outer layer

• Inner conductor, insulating layer, metallic shield, outer insulating layer.

What type of twisted pair cable is commonly used in Ethernet networks?

• Category 3 (Cat 3) twisted pair cable

• Category 5e (Cat 5e) or Category 6 (Cat 6) twisted pair cable

• Fiber optic cable

• Coaxial cable

What are the benefits of using fiber optic cables for internet connections?

• Increased power consumption

• Lower costs but slower speeds

• The benefits of using fiber optic cables for internet connections include higher speeds, greater bandwidth, reduced interference, longer transmission distances, and enhanced security.

• Limited availability in urban areas

How does electromagnetic interference affect twisted pair and coaxial cables?

• EMI affects twisted pair cables by causing noise, but they are somewhat resistant due to their design. Coaxial cables are better shielded against EMI, but can still be impacted.

• EMI has no impact on the performance of any type of cable.

• Twisted pair cables are completely immune to EMI effects.

• Coaxial cables are more prone to EMI than twisted pair cables.
