AIM – Study of different types of Network cables and Practically implement the cross – wired cable and
straight through cable using crimping tool.
Apparatus – RJ – 45 CONNECTOR, CRIMPING TOOL, TWISTED PAIR CABLE.
Theory – A cable is a medium through which information is usually transferred from one device to
another with a network.
Guided Media – a physical medium through which the signals are transmitted.
Types of Guided Media: -
1. Twisted pair cable - consist of a pair of conductors which are made of copper and each has a
single insulation. The pair of conductor are twisted together hence the name twisted pair.
The number of turns/foot determines the reduction degree of noise interference.
Increasing the number of turns/foot decreases noise interference.

2. Coaxial cables – the cable here contains a pair of parallel conductors. The inside
conductor is made of copper, and the outside conductor is made of copper mesh.
Unguided Media – it transmits the waves (electromagnetic) without any physical mediums. Hence
wireless transmission.
Types of unguided media –
Radio waves- they are electromagnetic waves which are transmitted in free space hence they are
omnidirectional and range is 1 to 3khz.
Infrared – An infrared transmission is wireless technology used for communication over short ranges
and range from 300 to 400 GHz.
Procedure –
Step 1 – Use cable strippers at about 2 inches from the end to remove the outer jacket.
Step 2: Untwist the twisted pair wires.
Step 3: Align the untwisted wires in the order necessary.
Step 4: Cut the extra wire. Once you've untwisted the wires, you'll have a superfluous amount of copper
wiring left; we don't need this much. Use the wire-cutting scissors to cut these off.
Step 5: Push the remaining wires into the RJ45 head according to color code. Be careful not to bend the
wires while pushing them in or you run the risk of creating a bad cable.
