Networking Cable is the medium through which information usually moves from one network device to
another. There are several types of cable which are commonly used with LANs. In some cases, a network
will utilize only one type of cable, other networks will use a variety of cable types. The type of cable
chosen for a network is related to the network's topology, protocol, and size. Understanding the
characteristics of different types of cable and how they relate to other aspects of a network is necessary
for the development of a successful network.
This is a notes about Cables & Connectors of computer networks. It contain details about the information of different types of cables- twisted pair cable, coaxial cable, fiber optical cable, crossover cable , straight through cable, STP/UTP cables & about their connectors.

4. Objectives:
1. Identify different types of cables used in
networking.
2. Identify network cable used in connecting
devices.
3. List down the materials needed and the
steps in
creating an Ethernet cable.
5. Cable is the medium
through which information
usually moves from one
network device to another.
6. Network Media
The network can be connected
through two types of connections:
Wire
d
Wireless
- more reliable than a
wireless connection
- widely used by some devices
such as cellphones and
laptops for their portability
7. Different wired connections commonly
used in networking:
1. Unshielded Twisted Pair (UTP) Cable
- a popular type of cable
- used for Local Area Networks.
- it has a two shielded wires twisted around each ot
8. 2. Shielded Twisted Pair (STP) Cable
The extra covering of the STP Cable
provides extra protection to prevent
electromagnetic interference.
9. 3. Coaxial Cable
- commonly used in television industries
- The metal shield surrounding the cable helps block
interference from fluorescence lights, motors, and
other computers.
10. 4. Fiber Optic Cable
- Transmits light rather than electronic signals which
reduce the risks of electrical interference.
- It is ideal for environments where electrical
interference is present.
12. Wireless Networks
- any type of computer network that use
wireless data connections for connecting
network nodes.
13. Types of Wireless Networks:
1. Wireless PAN (Wireless Personal Area
Network)
Ex. Bluetooth and Infrared
2. Wireless LAN (WLANs)
Ex. Wi-Fi
3. Wireless Mesh Networks
Ex. Wireless MAN, Wireless WAN,
Global Area Network and Space
Network

23. Directions: Watch the video to learn how to create straight-through
and crossover cables. While watching the video, list down the
materials needed as well as the steps in creating straight - through
and crossover cables. Write your answer on a separate sheet of paper.
Materials Needed: Steps in creating an Ethernet Cable:
Activity 2: Creating Network Cables
RJ45/Registered Jack
CAT5 UTP Cables
Crimping Tools
Wire Stripper
Side Cutting Pliers
LAN Testers
1. Prepare all the materials needed
2. Pull out one meter of Cat5 UTP
Cable
3. Using the cable stripper, peel the jacket of the UTP
cable.
The peeled part of the cable should approximately be 1
inch
4. Arrange the wires in the proper color-coding sequence
5. Refer to the color-coding table for either straight-
through or
crossover
6. Trim the end of the wires to make sure the ends are
equal
7. Carefully insert the wires into the RJ45
8. Lock it in using the crimping tool
9. Do this for both ends of the straight-through and cross
over cables.
10. Test the connectivity of the cables using a LAN tester.
24. Directions: Identify whether the cable needed in
connecting the following devices is Straight-Through cable
or Crossover cable. Write ST for straight – through and CO
