Working with Ethernet cables might sound tricky, but it doesn’t have to be. If you've ever wondered how to terminate an Ethernet cable, you're in the right spot. Whether you're setting up a home network or fixing a connection at work, understanding Ethernet termination can save time and money.
Instead of calling a technician every time something goes wrong, you can handle the cable yourself. This guide shows you step-by-step how to get it done. We all provide you with just what you need to get the job done. Let’s dive into terminating Ethernet cable the easy way.
About Copper Network Cable and RJ45 Connector
Most Ethernet cables use copper. Copper is a good choice because it handles data fast and keeps the signal clean. These cables often connect to an RJ45 connector at each end. That’s the plastic cap with gold pins you plug into routers or computers. Without proper ends, your cable won’t do anything. The RJ45 helps wires stay in place and transfers the signal from the cable into the device.
RJ45 connectors match with different types of Ethernet cables. CAT5, CAT6, and CAT6a are common. You can use this same guide to terminate an Ethernet cable, no matter which type you have. The key is lining up the wires right and making a tight connection.
Step-by-Step Guide: How to Terminate CAT6 Cable?
Before you begin, take a breath. This isn’t rocket science. Follow each step and check your work as you go. Terminating a cable means putting a working connector on the end so it can be used in a network.
This guide shows you how to terminate an Ethernet cable using a simple method. It doesn’t matter if you’re learning how to put Ethernet cable ends on or trying to fix a mistake. Just follow along.
Step 1 - Materials and Tools Needed
Before you start terminating an Ethernet cable, double-check your gear. A cable with a cut wire won’t work right. Make sure your tools are sharp and ready. Here’s what you’ll need:
- A CAT6 Ethernet cable
- RJ45 connectors
- Cable stripper
- Crimping tool
- Scissors or snips
- Boot (optional, for cable protection)
Step 2 – Choose Between T568A or T568B
There are two wiring styles: T568A and T568B. They use the same wires, just in a different order. Both work fine, but you must pick one and stick with it on both ends of the cable.
Most people use T568B. Look at a chart or the colors printed on the RJ45 connector box. It helps when deciding how to terminate a network cable without guessing.
If you mix them up, your connection won’t work. That’s a big no-no when you're learning how to put an end on an Ethernet cable the right way.
Step 3 - Install the Boot
If you're using a boot, slide it on now. Once the connector is attached, the boot won’t fit. It keeps the Ethernet cable ends protected and helps prevent bending.
Boots are optional. Still, it’s smart to use them for longer-lasting cables. Especially if the cable will be moved or unplugged a lot.
Step 4 - Strip the Cable
Take your stripper tool and cut off about one inch of the outer jacket. Be gentle. You want to remove just the plastic jacket and not the wires inside.
Now you’ll see four twisted pairs. These are eight wires in total, twisted into four groups. This is where you have to untwist them. Once that is done, you need to flatten and arrange the wires in the correct T568A or T568B order.
This is where a lot of mistakes happen in LAN cable termination. If your colors are in the wrong order, the cable won’t connect properly.
Step 5 - Insert Cable Wires
Cut the wires to make sure they're the same length, and they should be straight and even. Next up, you need to slide them into the RJ45 connector. Each wire must go into its own slot and touch the end.
After that, push the wires in until you feel them hit the front of the Ethernet end. Look from the side and double-check the color order. An important thing to do here is to make sure no wire is short or missing.
If you're figuring out how to put ethernet cable ends on, this part matters most. One small mistake means you have to start again.
Step 6 - Crimp the RJ45 Connector
Now insert the connector into your crimping tool. Squeeze the handle hard. This locks the wires into the pins and seals the connection.
This step is what makes your cable work. If the crimp is loose, your device may not get a connection. That’s the last thing you want after doing all this.
Learning how to terminate ethernet cable means knowing how to use this tool right. Don’t be afraid to press hard since you want a solid bond between the wires and the connector.
Step 7 - Don’t Forget the Final Step
Pull on the cable a little to check if the wires are secure. If it’s loose or the wires slide out, you’ll need to try again. You can also test it with a cable tester.
Slide the boot up to cover the connector if you used one. That’s it! You just learned how to terminate an Ethernet cable from start to finish.
And yes, you can even shorten ethernet cable by cutting and repeating this same process on a fresh end.
Final Words
Knowing how to put ethernet cable ends on helps in homes, schools, and offices. Once you get the hang of terminating ethernet cable, it feels like second nature.
Doing it yourself saves cash and builds confidence. And if you need high-quality parts to get started, then check out TS Cables for top-rated RJ45 connectors, Ethernet caps, and everything else you’ll need to terminate Ethernet cable the right way.
FAQs
Q1: What is the difference between T568A and T568B?
They use the same wires but in different color orders. Just pick one and stay consistent on both cable ends.
Q2: Can I reuse a connector if I make a mistake?
No. Once you crimp an RJ45, it can’t be used again. Always keep a few extras on hand.
Q3: How do I shorten an Ethernet cable without damaging it?
Cut the cable cleanly, strip the jacket, and follow the same steps to install a new connector.
Q4: Is it easy to learn how to unplug an Ethernet cable safely?
Yes. Press the small clip on the connector and gently pull the cable straight out.
Q5: Can I use this method for CAT5 or CAT6a cables too?
Yes. These steps work for all twisted-pair copper network cables using RJ45 connectors.
