Cabling

Question 1

What is twisted pair cabling?

Answer 1

For short and medium length connections because of lower costs compared to optical fiber.
To reduce crosstalk two insulated copper wires are twisted around each other.

Question 2

What are the advantages and disadvantages of Unshielded Twisted Paired (UTP) Cable?

Answer 2

Cheap and easy to work

Can be affected by radio interference

Question 3

What is CAT1 - CAT7?

Answer 3

The type of UTP cable, higher numbers mean more twists in the cable so greater speeds and length

Question 4

What are the characteristics of Shield Twisted Pair Cabling (STP)?

Answer 4

Same as UTP with a shield covering the full wire length to reduce interference

Question 5

What are the characteristics of a coaxial cable?

Answer 5

Insulated and shielded by a braided wire. Most expensive, but least interference

Question 6

What are the characteristics optic fibre?

Answer 6

Fibers of glass used to carry signals in the form of light over long distances. Cheaper than Coaxial

Question 7

What are single mode fibers?

Answer 7

Transmit one signal per fiber

Question 8

What are Multi-mode fibers?

Answer 8

Transmit many signals per fiber
