How to Make an Ethernet Patch Cable

How to Make an Ethernet Patch Cable

Making your own Ethernet patch cable allows you to create a cable that perfectly fits your needs in terms of length and aesthetics. This guide provides step-by-step instructions on selecting the right tools and components, choosing a wiring standard, assembling the connector, crimping, and testing to create a fully functional Cat5e or Cat6 Ethernet cable.

Necessary Tools and Components

Before starting, ensure you have the required tools and components:

  • Cat5e or Cat6 unshielded twisted pair (UTP) cable – Cat6 supports faster transfer speeds up to 10Gbps
  • RJ45 connectors – Use Ethernet cable plugs designed for stranded or solid core cables
  • Crimping tool – Ensure it can handle the cable thickness
  • Cable stripper
  • Cable tester – Essential for troubleshooting faults

Complete network cabling tool kits like the TRENDnet Network Installation Tool Kit provide all the required tools and consumables.

Choosing the Right Ethernet Cable

For most home and office networks, Cat5e and Cat6 will both effectively support 1Gbps and 10Gbps speeds respectively. Cat6 works well for future-proofing networks as it supports faster transfer speeds up to 10Gbps.

T568A vs T568B Wiring Standards

Ethernet cables follow either T568A or T568B wiring standardsT568B is the most widely used . The tables below show the color coding for both standards:

T568B

Pin Wire Color
1 White/Orange
2 Orange
3 White/Green
4 Blue
5 White/Blue
6 Green
7 White/Brown
8 Brown

T568A

Pin Wire Color
1 White/Green
2 Green
3 White/Orange
4 Blue
5 White/Blue
6 Orange
7 White/Brown
8 Brown

Step-by-Step Instructions

Follow these steps to create your own Ethernet patch cable:

  1. Cut and strip the cable – Leave 1/2″ of exposed wires
  2. Untwist wire pairs and straighten wires
  3. Arrange wires based on T568A or T568B standard
  4. Trim wire ends evenly 1/2 inch from jacket
  5. Insert wires fully into RJ45 plug
  6. Crimp the connector
  7. Repeat steps for other end
  8. Test cable for faults

Conclusion

With some basic tools and components, making DIY Ethernet cables is straightforward. Testing each connector ensures the cable is wired correctly and prevents network issues. This allows you to create durable, long-lasting patch cables tailored to your exact requirements.
