Ethernet cable is the most used protocol today. It is used all over the world and majority of households have ether net cables. Many devices shipped today provide Ethernet cables with them. However these Ethernet cables are at most four feet long. It is a standard length on which the cables are shipped.

If you are an owner of a larger network or you have to place a device on higher ground but the length is not long enough.Well there are a couple of options. You could buy new cables, you could pre-order longer cables or you can make one yourself.

Ethernet Cables

Steps to Make Ethernet Cables

Making ether net cable is not as difficult as it seems. There are benefits in making ether net cables yourself.

  • You can adjust the length of the cable to your requirements.
  • You can make as many cables as you want.
  • It is less costly than pre ordering new cables.


As for startup you might need to make a small investment. This is only one time investment if you are beginner. You’ll need

  • Ether cables.
  • Spool of cat5 (plenum or PVC jackets).
  • RJ-45 plugs.
  • Wire cutter/ scissors.
  • RJ-45 crimper.

You can buy a 50 count bag of ether cables as this would be cheaper. You need a lot of cables if you want to make a large ether cable. Making ether cables may seem but it isn’t. It is a little time consuming but it is cheaper and it is fun to make.

Step 1

Firstly you need to see which cable type you need.  There are two basic types of cables

  • Straight through cables
  • Cross over cables

Some devices that use straight through cables are Routers, switches network hard ware adapters, NASes etc. the cable shipped with these devices are straight through by standard. Older devices however use cross over cables. Not all but mostly old devices use cross over cables to connect with their switches. Hubs also use cross over cables to connect with other hubs. Cross over cables can also be used to connect two laptops.

If you don’t have an idea of what type of cable is compatible with your device then there is no need to worry. Auto-MDIX is just the thing for you. It tells what type of cable is compatible with your devices network ports.

For older devices you can simply see it in devices documents.

Step 2

Collect the tools you need. You need a spool of cat5 or cat5e. These are the standard spools. In case of gigabit Ethernet network you can use cat6. These cables can have a plenum to PVC jacket.

Now both are compatible with your device but the thing is that PVC is cheaper and it is made up of a substance that releases a toxic smoke when it burns. This is banned in most buildings as a safety hazard. If you residence allows PVC cables then it is best to work with PVC cable as it is cheap and is easier to work with as compared to plenum.

Plenum is safe on the other hand. It doesn’t release toxic gases and it has soft wires. Due to these soft wires, it is best to work with PVC cables for beginners.

You’ll also need Rj-45 plugs. These heads are attacked to both ends of the wires. Of course a wire cutters and an Rj-45 crimper.

All this equipment is available online or nearby electronic or tool store.

Step 3

Now to get started. Cut the wire according to required length. Once done, cut an inch of jacket off of both ends of the wire.

When you are take the jacket off you will see four set of wires. When you strip the wire, be careful to not mess up with any inner wires. These wires are the key to your connection.

Step 4

Once you see the inner wiring, now arrange them accordingly to network port type of your device. Untwist the twisted inner wires and you will see colorful individual wires.

For straight through

For straight through cables arrange the wires from left to right in the mentioned order e.g. white-orange, orange, white-green, blue, white-blue, green, white-brown, and brown.

For cross over

For cross over cable, the wiring is a little different at both ends.

  • At one end arrange the wire as white-green, green, white-orange, blue, white-blue, orange, white-brown, brown
  • At the other end the order is the same as a straight through cable that is white-orange, orange, white-green, blue, white-blue, green, white-brown, and brown.

Step 5

Now the most important and tricky part. Insert the wires in to the Rj-45 plug. Mistake in this step may cause faults in your final cable.

Now straighten out the wires at both ends. Try to straight them out as much as possible because it makes it easier and more error free. Now insert the wires in to the Rj-45 plug. Join the wires tight together and hold them tightly just like that. Now hold the Rj-45 plug with the clip side down and other side facing towards you. Insert the wires.

There should be no wires between the jacket of the wires and the plug. The wires will smoothly slip inside the plug and they will fit the snug themselves. If the wires are being problematic then straight them out and try again.

Step 6

Now the crimper comes in to work. Take the crimper and crimp the plug. It should not too hard and not too soft. Press it firm enough so the plug stays in place and fits the wire.

Step 7

Finally test the cable. Connect the cable to the network port. The LED will indicate that if the cable is surely connected or not. Now you have a cable of your desired length and type.

Check if that you get a strong signal through the cable. If the signal is not strong enough of faulty. Crimp the plug once again to secure the connection between the wires and plug.
