MEDIUM

Identify various types of cables such as Unshielded Twisted Pair (UTP), Shielded Twisted Pair (STP), coaxial and fiber optic cable

Shielded Twisted-Pair Cable

• Its Four pairs of colour-coded wires are each wrapped in metallic foil, and all four are then collectively wrapped in a layer of metallic braid or foil. Finally, this layer is wrapped with outer jacket.

Unshielded Twisted-Pair Cable

• Consist of two wires or conductor twisted together, each with it own plastic insulation. Cancel out the electromagnetic interference that can cause crosstalk, the noise generated by adjacent pairs.

Coaxial Cable

• The coaxial cable, often referred to as ‘coax’, consists of a single copper wire surrounded by at least three layers. They are an insulating material, a woven or braided metal and a plastic outer coating. This cable is often used as cable television (CATV) network wiring because it can be cabled over longer distances in comparison to the twisted-pair cable.

Fibre Optic Cable

• The fibre optic cable is a networking medium that uses light for data transmission. The intensity of light is increased and decreased to represent binary one and zero. The binary system is a way of counting using just the two numbers 0 and 1.
