Have you ever required a short Ethernet cable, but none of the ones in your closet are shorter than six feet? You could wrap the excess cable, but for a cleaner look, shorten the wire yourself. You may even create your custom-length network cables using the correct components. We will learn how to crimp ethernet cables in the article below.

You can Crimp Ethernet Cable in a few steps. Calculate the length of the wire you need > Remove the outer jacket >Separate and untwist all cables> Arrange the wires correctly and prepare them for crimping > Slide the connector on and trip it. This way, you can crimp the wire easily. To know about the steps in detail, keep on reading.

You can construct whatever length of Ethernet cable you desire by networking cable crimping it yourself. Pre-made Ethernet cables are only accessible in specific measurements, and you may require a size that isn’t available. Again, you may always go longer than necessary, but it wastes time. Making your own Ethernet cables is far less expensive than purchasing them pre-made. Let us now see how to crimp the ethernet cable.

What You’ll Need To Crimp Ethernet Cable| 5 Tools

We have listed the tools and supplies you’ll need to crimp ethernet cables. That is:

  • Ethernet cable in bulk (raw copper, not copper-clad aluminum)
  • RJ-45 interfaces
  • Relief boots (optional but beneficial in protecting the connection)
  • Wire cutters, wire strippers, or scissors
  • RJ-45 crimping tool ethernet crimping tools

How To Crimp Ethernet Cable |5 Steps

Do you have everything? Let’s get the steps on how to crimp ethernet cable started.

Step One: Measure the Length of the Wire You Need

Take your Ethernet wire and cut it to the length you want.

Don’t worry about obtaining the precise length; if anything, you’ll want a little more at the end to compensate for any differences and errors—you can always cut away the excess and build another Ethernet cable out of it later. ether cable in bulk

Cut the cable using wire cutters or scissors after you’ve reached the desired length. wire cutter

After you cut it, put on a relieving boot before you start tampering with the wires and installing the connection because you won’t be able to slip it on once the connector is installed.

Step Two: Remove the Outer Jacket

Remove 2-3 inches of the cable’s outer jacket using your crimping tool from each end. Insert the cable into this slot, then spin the network cables crimping tool to cut around the jacket.

The jacket may then be removed to expose the tiny wires within. The crimping device will feature a razor blade part with enough room to cut through the coat but not the internal wires.  remove outer jacket

You may also detect a series of fragile hair-like strands. The primary reason those strands are there is so you can draw them down and take away even more of the outer jacket. This offers extra cable strength when you pull on it, preventing the interior wires from receiving all the load.

But why do it? As when you use your crimping tool to remove the outer jacket, there’s always the potential that you’ll nick the interior wires slightly.

By pushing on the fiber strands to remove further of the outer jacket and then cutting the internal wires just below the probable nick, you eliminate all danger of a cable fault.

If you are careful with the crimping tool then you don’t have to do this, but it’s an extra precaution you may take.

Step Three: Separate and Untwist all of the Wires

When the inner wires are exposed, you’ll see four pairs of wires twisted together, for a total of eight wires. These pairs are available in a variety of colors, with one being a solid color while the other is a white wire with a matching stripe. untwisted wires

Untwist all four pairs of wires to create eight different cables. It’s also a good idea to level down the wires as much as possible because they’ll still be wavy after untwisting.

Step Four: Arrange the Wires Correctly and Prepare them for Crimping

Next, we must place the eight wires in a specific arrangement, which may need some practice.

Technically, the wires can be in any sequence in all both ends are connected the same way. On the other hand, Ethernet wires have wiring sequence specifications known as T-568A and T-568B. rj 45 interfaces

The one and only difference is the orange and green wire pairs have been swapped. But, in the first place, why are there two different standards?

It’s mainly for the sake of having crossover Ethernet wires. Crossover wires connect two machines without the usage of a router. T-568A is used at one cable end, while T-568B is used at the other.

However, in the case of a standard Ethernet cable, both ends will have an identical wiring sequence.

It doesn’t matter which one you choose when constructing your Ethernet wires. T-568B is quite prevalent in the United States since it is compatible with older telephone equipment and may be connected to an Ethernet connector that utilizes T-568B.

T-568B is used in the making of majority of pre-made Ethernet cables.t568a and t568b

T-568A is getting increasingly popular and recommended. In addition, it is more frequent throughout the rest of the world. So, with that in mind, we’ll be utilizing T-568A for this instruction.

For Making a Solid Connection

Get our eight wires organized and ready to crimp. Lay the wires over the side of your index finger and press them down with your thumb to keep them in place.

Once the wires are in place, link them closer together and start working them back and forth to harden them. Keep a firm grasp on the wires during this operation.

You will eventually be able to relax your grasp on the wires, and they should mainly stay in place without veering off in different directions. It is done in 30 seconds. solid connection

Next, take your scissors and trim the excess wiring so that there is only approximately a half-inch between the end and the beginning of the outer jacket. The idea is to have the wires short enough to push the outer jacket into the connector before crimping the connector over the jacket for a solid connection (more on that later).

After a few tries, you’ll gain a better feel for it.

Step Five: Slide the Connector On And Trip It

Grab the Ethernet plug connector and insert the wires inside, ensuring each wire fits into its slot, with the clip part facing away from you and the green wires to the floor (or the ceiling, depending on orientation).

As you do this, be sure that neither of the wires has jumped out of position. Remove the connector, fix the wires, and try again if this is the case.

Insert the cable until all eight wires contact the connector’s end. It may be necessary to shake it and use some effort to get the connection on. ethernet plug connector

Next, use your crimping tool and insert the connection as far as it goes into the crimping slot. It will only go in one direction, so if it doesn’t go all the way on one side, turn the tool around and reinsert the connection.

The entire connection should fit inside the crimping tool.

Pull down on the tool when the connector is fully inserted, to crimp ethernet cables. Squeeze down, but not too hard. Again, the more you practice, the better you’ll get.

After that, take the cable from the tool and verify the connection to ensure everything is working. If done correctly, the pointed crimp at the back of the connection should squeeze down on the cable’s outer jacket rather than the smaller wires.

If not, you did not remove enough extra wire from the smaller wires.

Then, if you’re using them, place the relief boot over the connection and bask in the joy of your Ethernet cable. Just make sure to finish the other end! relief boots

Ethernet connections can be as long or as short as you wish, but there is a physical restriction of 300 feet for Ethernet. So keep them under that length, which shouldn’t be too difficult for the most part.


What is the purpose of an Ethernet crimp?

When you crimp a cable, the metal contact pads within the RJ45 head 'cut' into the isolated ethernet connection. Most RJ45 connections feature a piece in the center is crushed during crimping, guaranteeing that the cable does not readily come from the contact pads. So this is the purpose of ethernet crimp.

What does crimping serve?

People often use crimping to secure bullets in cartridge casings, make quick but strong electrical connections, secure lids on metal food cans, and for various other purposes.. Crimping may produce a strong connection between a workpiece and a non-metallic component because it is a cold-working method.

Is an Ethernet crimping tool required?

The most necessary instrument is an RJ45 crimp tool. Although crimping ethernet wires without this specialized equipment is technically feasible, it is not particularly practical for crimping many cables.

What is the definition of a crimping system?

Crimping is a method of joining wires or connecting wires to other connections often used in electrical work. 'Crimp connectors' is the general term for the fittings that attach to the wire, typically consisting of an insulated sleeve attached to a metal connection.


You should now be able to crimp ethernet wires on your own. Knowing how to crimp wires gives you much freedom with your home network. You’ll also discover that if you have these talents, you can assist many of your friends with their networks.
