How to Make Cat 5 Cable Ends

Cat 5 cables are widely used in networking to connect devices and transfer data. Making your own Cat 5 cable ends can save you time and money, and also provide you with the flexibility to customize cable lengths according to your specific needs. In this article, we will guide you through the process of making Cat 5 cable ends, step by step.

Materials Needed:
– Cat 5 cable
– RJ-45 connectors
– Crimping tool
– Wire stripper
– Cable tester (optional)

Step 1: Prepare the Cable
Start by measuring the desired length of your cable and cut it accordingly. Use a wire stripper to remove approximately 1 inch of the outer jacket, exposing the four twisted pairs of wires inside. Be careful not to damage the wires while stripping the jacket.

Step 2: Untwist and Arrange Wires
Untwist each pair of wires and arrange them according to the T568B wiring standard. The T568B standard is widely used and ensures compatibility with most networking devices. The arrangement should be as follows:
– Pair 1 (Blue pair): Blue wire with white stripe (Pin 5), and white wire with blue stripe (Pin 4).
– Pair 2 (Orange pair): Orange wire with white stripe (Pin 1), and white wire with orange stripe (Pin 2).
– Pair 3 (Green pair): Green wire with white stripe (Pin 3), and white wire with green stripe (Pin 6).
– Pair 4 (Brown pair): Brown wire with white stripe (Pin 7), and white wire with brown stripe (Pin 8).

Step 3: Trim and Align Wires
Trim the excess wires to ensure they are all the same length. Insert the wires into the RJ-45 connector, making sure they are aligned with the correct pins. The connector should have small guide channels that hold the wires in place.

Step 4: Crimp the Connector
Using a crimping tool, firmly press down on the connector to crimp it onto the cable. This action will secure the wires and create a strong connection. Repeat the process for the other end of the cable if needed.

Step 5: Test the Cable (Optional)
If you have a cable tester, it is recommended to use it to ensure the cable is properly made and functions correctly. The tester will indicate if there are any wiring issues or faults.


Q: Can I use Cat 5e or Cat 6 cables instead of Cat 5?
A: Yes, Cat 5e and Cat 6 cables can be used interchangeably with Cat 5 cables. They offer higher performance and can handle faster data transfer speeds.

Q: What if I accidentally cut the wires too short?
A: If the wires are too short to reach the pins inside the RJ-45 connector, you will need to start with a new piece of cable and repeat the process.

Q: Can I use a different wiring standard?
A: While the T568B standard is recommended for compatibility, you can use the T568A standard as well. Just make sure to use the same standard on both ends of the cable.

Q: Are there any special considerations when making crossover cables?
A: Yes, crossover cables require a specific wiring configuration to allow direct communication between two devices. You can find crossover wiring diagrams online to guide you through the process.

In conclusion, making your own Cat 5 cable ends can be a straightforward process if you follow the steps outlined above. It allows for customization and can save you money in the long run. Just remember to use the correct wiring standard, ensure proper alignment of the wires, and test the cable if possible.
