In today’s connected world, a stable, high-speed network is the backbone of any successful home or business operation. While pre-made patch cords are convenient, learning how to wire your own Cat6 Ethernet cables offers unparalleled flexibility. It allows you to create custom-length cables for clean, professional-looking installations, repair damaged connectors, and save on costs for large projects. At D-Lay Cable, with over 26 years of experience manufacturing high-performance cabling solutions, we believe in empowering our clients with knowledge. dlaycable will walk you through the professional process of terminating a Cat6 cable, ensuring a reliable, high-speed connection every time.
Before You Begin: Gathering Your Tools & Materials
A successful outcome starts with the right equipment. Using professional-grade tools and high-quality materials is not just a recommendation; it’s a requirement for a cable that meets Cat6 performance standards. Skimping here can lead to signal loss, slow speeds, and connection drops.
Essential Tools
- Crimping Tool (for RJ45): This is the primary tool for attaching the RJ45 connector to the cable. A good quality crimper ensures a solid, uniform connection.
- Cable Stripper/Cutter: While many crimpers have a built-in stripper, a dedicated tool provides a cleaner, more precise cut without nicking the inner conductor wires.
- Network Cable Tester: This is a non-negotiable final step. A tester verifies that all eight wires are correctly wired and making a good connection, saving you hours of troubleshooting later.
High-Quality Materials
- Bulk Cat6 Cable: The foundation of your network. At D-Lay Cable, our UL/ETL certified Cat6 cables are manufactured with pure copper conductors to guarantee optimal performance and data integrity. Choose between Unshielded Twisted Pair (UTP) for general use or Shielded Twisted Pair (STP) for environments with high electromagnetic interference (EMI).
- Cat6 RJ45 Connectors/Plugs: These are the small plastic ends of the cable. Ensure they are specifically rated for Cat6. Cat6 connectors often have staggered pins to reduce crosstalk between the wires, a key feature for achieving gigabit speeds.
The Blueprint: Understanding T568A vs. T568B Wiring Standards
Before you cut a single wire, you must understand the two standard wiring schemes: T568A and T568B. These standards define the specific order in which the eight colored wires are placed into the RJ45 connector. To create a standard “straight-through” cable (used for connecting a computer to a switch, router, or wall jack), you must use the same standard on both ends of the cable.
Which one should you use? While both are functionally identical, T568B is the more common standard in the United States and for new network installations. For consistency and to align with industry practice, we recommend using T568B. The most important rule is to be consistent across your entire network project.
Color Code Pin-out (Looking at the connector with the tab facing down)
| Pin | T568B Standard (Recommended) | T568A Standard |
|---|---|---|
| 1 | White/Orange | White/Green |
| 2 | Orange | Green |
| 3 | White/Green | White/Orange |
| 4 | Blue | Blue |
| 5 | White/Blue | White/Blue |
| 6 | Green | Orange |
| 7 | White/Brown | White/Brown |
| 8 | Brown | Brown |
Step-by-Step Guide: How to Terminate a Cat6 Cable with an RJ45 Connector
With your tools, materials, and chosen standard (we’ll proceed with T568B), you’re ready to create your cable. Work carefully and methodically.
-
Step 1: Prepare the Cable
Using your cable stripper, carefully score and remove about 1 inch (2.5 cm) of the outer PVC jacket from the end of the cable. Be gentle to avoid cutting into the twisted pairs inside. Once scored, the jacket should pull off easily.
-
Step 2: Expose and Arrange the Wires
Inside, you will see four twisted pairs of wires. Many Cat6 cables also include a plastic spine (spline) that separates the pairs to reduce crosstalk. Cut this spline off as close to the jacket as possible. Then, carefully untwist each of the four pairs and straighten them out as much as you can.
-
Step 3: Align Wires to the T568B Standard
This is the most critical step. Arrange the eight straightened wires side-by-side in the correct T568B order, from left to right: White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown. Flatten them and hold them tightly together between your thumb and forefinger.
-
Step 4: Trim and Insert Wires into the RJ45 Connector
Keeping the wires in the correct order, use the cutter to trim the ends so they are perfectly flat and extend about 1/2 inch (1.25 cm) from the edge of the jacket. Hold the RJ45 connector with the tab facing down and gently slide the aligned wires into the connector. Push firmly until all wires have reached the very end of the connector. You should be able to see the copper ends of the wires through the clear tip of the plug. Ensure the cable jacket is also pushed inside the base of the connector for proper strain relief.
-
Step 5: Crimp the Connector Securely
Double-check the wire order one last time. If it’s correct, insert the connector into the appropriate slot on your crimping tool. Squeeze the handles of the crimper firmly and completely. You should hear a click. This action does two things: it pushes the gold-plated pins into each wire, creating the connection, and it secures the cable jacket at the base of the connector.
-
Step 6: Repeat for the Other End
Follow steps 1-5 precisely on the other end of the cable, using the same T568B standard to create your straight-through cable.
The Final Check: Testing Your New Cable for Perfection
Do not skip this step! Plug both ends of your newly created cable into your network cable tester. A good tester has a main unit and a remote unit. Turn it on and watch the lights. For a perfectly wired straight-through cable, the lights on both units should illuminate sequentially from 1 to 8 in perfect synchronization. If any lights are out of order, dim, or do not light up at all, you have a fault and will need to cut off the connector and re-terminate that end.
Pro-Tips from the Experts at D-Lay Cable
- Maintain the Twist: The twists in the wire pairs are crucial for preventing signal interference. Keep the wires twisted as close to the connector as possible. Do not untwist more than 1/2 inch (1.25 cm) as per industry standards.
- Check, Double-Check, Crimp: Visually inspect the wire order through the clear connector one final time before crimping. Once you crimp, there’s no going back.
- Quality In, Quality Out: The performance of your network is only as strong as its weakest link. Using factory-direct, certified components like those from D-Lay Cable ensures that your handcrafted cable can support the full bandwidth and speed of your network infrastructure.
