Making the Connection- How to Terminate and Test Internet LAN Cables


In the modern world, the internet has become an indispensable tool for both personal and professional life. To establish a reliable and high-speed connection, it is crucial to have properly terminated and tested LAN cables. This comprehensive guide, “Making the Connection: How to Terminate and Test Internet LAN Cables,” provides step-by-step instructions and insights into the process of creating and verifying functional network cables.

Identifying Cable Types

The first step in terminating LAN cables is to identify the type of cable you will be using. The most common types are Cat5e, Cat6, and Cat7, each with different speed ratings and capabilities. Determine which type is suitable for your specific needs and the distance you need to cover.

Gathering Tools and Materials

Before beginning the termination process, gather the necessary tools and materials. This includes a crimper, wire strippers, RJ-45 connectors, and a cable tester. Ensure that you have the correct tools for the type of cable you are using, as using the wrong ones can damage the wires or connectors.

Stripping the Cable Jacket

Using wire strippers, carefully remove about 1 inch of the cable jacket from the end of the cable. Expose the four twisted pairs without nicking or cutting the individual wires. Straighten the wires and separate them into individual strands.

Arranging the Wire Pairs

The next step is to arrange the wire pairs in the correct order according to the wiring scheme you are using. For standard Ethernet connections, the TIA/EIA-568B wiring scheme is commonly used:

– White/Orange

– Orange

– White/Green

– Blue

– White/Blue

– Green

– White/Brown

– Brown

Inserting Wires into Connector

Insert the wires into the RJ-45 connector in the correct order. Ensure that the wires are fully seated at the back of the connector and flush with the front. Use the crimper to firmly crimp the connector onto the cable, securing the wires in place.

Testing the Cable

Once the cable is terminated, it is essential to test it to ensure proper connectivity and speed. Use a cable tester to verify that all the wires are connected correctly and that the cable can transmit data at the expected speed.

Troubleshooting Common Issues

If the cable test fails, it may be due to one or more common issues. These could include:

– Incorrect wiring order

– Damaged wires or connectors

– Poorly crimped connections

– Faulty cable or equipment

By troubleshooting and addressing these issues, you can establish a reliable and efficient LAN connection.


Terminating and testing LAN cables is a crucial aspect of network connectivity. By following the steps outlined in this guide, “Making the Connection: How to Terminate and Test Internet LAN Cables,” you can ensure that your cables are properly configured and ready to deliver optimal network performance. Remember to use the correct tools, observe the wiring schemes, and thoroughly test your cables to ensure a stable and reliable connection.
