How To Wire A Patch Cable

A patch cable, which is also called a patch cord, is a short cable that you can use to connect two electronic devices, such as a computer and a router, or two switches, or two servers. Generally, patch cables are used in local area network (LAN) installations, and they are also used in data center installations.

Introduction

Wiring a patch cable is an essential skill that every IT professional, network technician, and computer enthusiast should know. In this article, we're going to explain how to wire a patch cable using the twisted pair cable, which is the most commonly used type of cable in LAN installations.

Step 1: Gather Your Materials and Tools

Before you begin wiring your patch cable, you must first gather your materials and tools. Here's a list of what you'll need:

- Twisted pair cable

- RJ45 connectors

- Crimping tool

- Wire stripper

- Sharp scissors or a razor blade

Step 2: Preparing the Cable

Once you have all the materials and tools, you need to prepare the twisted pair cable. Follow these steps:

- Cut the cable to the desired length using sharp scissors or a razor blade.

- Using your wire stripper, take off the outer jacket of the cable, exposing the eight wires inside.

- Using your scissors or razor blade, straighten the wires by cutting any twists or kinks.

Step 3: Sorting and Aligning the Wires

Now, you need to sort and align the wires in the correct order. The wires are color-coded and should be sorted in this order:

- Orange/white

- Orange

- Green/white

- Blue

- Blue/white

- Green

- Brown/white

- Brown

Once the wires are sorted, align the ends of the wires by holding them together and straightening them out.

Step 4: Inserting the Wires into the RJ45 Connector

Using your wire cutter, trim the ends of the wires to make them even. Then, insert the wires into the RJ45 connector in the correct order. The order should be as follows:

- Pin 1 (Left to Right): Orange/white

- Pin 2 (Left to Right): Orange

- Pin 3 (Left to Right): Green/white

- Pin 4 (Left to Right): Blue

- Pin 5 (Left to Right): Blue/white

- Pin 6 (Left to Right): Green

- Pin 7 (Left to Right): Brown/white

- Pin 8 (Left to Right): Brown

Make sure the wires go all the way into the connector, and the jacket of the cable goes all the way to the end.

Step 5: Crimping the Connector

Once you have inserted the wires into the connector, use your crimping tool to crimp the connector onto the cable. Make sure you position the connector in the crimping tool according to the instructions provided, and then squeeze the tool until it makes a clicking sound.

Step 6: Testing the Patch Cable

The final step is to test the patch cable to ensure it is functional. You can do this by plugging the patch cable into your computer's Ethernet port and the other end into a switch or router. Check the connection's status on your computer, and if it is successful, then your patch cable is functioning correctly.

Conclusion

By following these six steps, you can easily wire a patch cable using the twisted pair cable. Remember to double-check your wires' order and make sure the connector is crimped correctly. With this skill, you can make your patch cables to any desired length, which allows for a clean and tidy cabling solution.
