1. Recommended Equipment Used with Diagrams

In this lab test, there are 4 equipment used for crimping network cables, which

are CAT 6 Cable, RJ45, Crimping Tool, Cutter and UTP Cable Tester.

A UTP Cat 6 cable is used to transmit data between devices in a network.

It provides a high-speed and reliable connection, supporting faster data transfer

rates compared to earlier versions. The "UTP" stands for "Unshielded Twisted

Pair," indicating that the cable consists of pairs of insulated copper wires twisted

together to reduce interference, while "Cat 6" signifies its category and capability

to handle higher bandwidth for efficient data communication in Ethernet

networks. Diagram 1 shows the cable that we are going to use for this lab test.

An RJ45 connector is used to connect network cables to devices like

computers, routers, and switches. It provides a standardized interface for

transmitting data in Ethernet networks, ensuring a reliable and consistent

connection. Diagram 2 shows the RJ45 that we are going to use for this lab test.

A crimping tool is used to attach connectors to the ends of cables

securely. It compresses the connector onto the cable, creating a strong and

reliable connection while a stripper is a tool that removes the outer insulation

from a cable, exposing the inner conductors. It ensures precise and clean

stripping, preparing the cable for termination or connection. The diagram below

shows the crimping tool and the stripper that we are going to use.

Construct Cable Network

Constructing a cable network, specifically referring to a LAN (Local Area

Network) cable network, involves the physical installation and setup of cables to

connect devices within a localized area. This process includes the deployment of

cables, connectors, and networking equipment

2. Obtaining and Cable Preparation with Diagrams

Using the cable that has been prepared, remove the outer layer of the cable to

untwist the 4 pairs of wires. The diagram below shows the process of stripping

the outer layer of the cable using the stripper.

Diagram 5: Cutting the outer layer of the cable

Untwisting the cable before crimping helps to ensure proper termination of the

wires to connectors, allowing for a reliable and effective electrical connection.

Diagram 6 shows the twisted pair cable before we untwist it.

2. Preparing and Inserting Wires with Diagrams

After straightening the wires, we need to arrange them following the industry

standards for proper pin configurations. Insert the wires that have been arranged

in the correct order into RJ45. As stated in 1 above, we are using

TIA/EIA-568-A standard wiring scheme for our lab test.

Diagram 7: Standard wiring scheme arrangement

2. Termination On The Other End Cable

The next step involves terminating the other end of the cable, employing the

same process as the previous step.

Initially, remove the outer layer of the cable to expose the four pairs of

wires, using a stripper tool. Following this, untwist and straighten the wires,

preparing them for termination. The arrangement of the wires follows industry

standards, TIA/EIA-568-A standard wiring scheme.

The arranged wires are then inserted into an RJ45 connector, aligning

them with the designated slots. A careful examination is conducted to detect any

damage in the cable and connector, verifying proper wire alignment and

adherence to color-coding standards.

Subsequently, a crimping tool is employed to securely compress the

connector onto the wires, establishing a robust and reliable connection. A

re-inspection is then carried out, thoroughly scrutinizing the crimped connector

for proper wire seating, accurate color-coding, and the absence of exposed

wires.

Cable Network Testing

Testing the connection cable ensures that the LAN cable establishes a reliable

and stable connection between devices, which is essential for maintaining

consistent and uninterrupted communication within a local network. Cable testing

plays a critical role in identifying issues that may impact network performance,

including problems like signal degradation, crosstalk, or interference.

Through testing, these issues can be detected and addressed, allowing for

the optimization of overall network performance. Additionally, testing contributes

to ensuring the security of the network. Faulty cables or insecure connections

could potentially be exploited by unauthorized individuals or malicious software.

Regular testing is instrumental in identifying and addressing security

vulnerabilities. In our lab test, we employ three methods for testing the network

cable: utilizing the cable tester, static IP, and dynamic IP.

3. Testing The Cable Using Cable Tester with Diagrams

Cable testers are devices specifically designed to pinpoint common issues such

as breaks, shorts, miswires, and other connectivity problems in cables.

DIagram 10: Testing the cable using cable tester

To effectively test a cable using a cable tester, it's crucial to ensure that both

ends of the cable are appropriately terminated with connectors. Once prepared,

power on the cable tester, noting that some testers may rely on batteries, while

others may need an external power source. Connect one end of the cable to the

main unit or transmitter of the cable tester and the other end to the remote unit or

Internet) 3. Testing Connection Cable Using Static IP (PC to PC) and Dynamic IP (LAN to

(LAN to Internet)

3.2. Static IP (PC to PC)

This testing method involves testing a cable connection between two devices

within a local network, such as two computers. Each device is manually assigned

a static IP address within the same subnet. There are a few steps that we use to

test the connection cable using static IP:

Step 1: Using the cable that we have crimp, we connect two PCs together via its

NICs.

Step 2: Test cable connection with UiTM LAN network using the following IP

address, subnet mask and DNS server addresses.

Step 3: Change IP configuration to Automatic DHCP and wait until the

connection is established.

3.2. Dynamic IP (LAN to Internet)

This testing method involves testing a cable connection that connects a device

within a local network to the internet. Devices on the local network obtain IP

addresses dynamically from an Internet Service Provider using DHCP. There are

a few steps that we use to test the connection cable using dynamic IP:

Step 1: Open Command Prompt. On the Command Prompt screen, type

ipconfig/all and it will display the Hostname, IP address, Subnet Mask, Default

Gateway, DHCP Server and other information about the current IP configuration.

Close the Command Prompt screen.

Diagram 21: The result of ipconfig/all

Step 2: Open Control Panel. Then find the Network and Internet option and

click on it.

Step 3: Find a Network and Sharing Centre. Click on that option and another

screen will pop out.
