How to Make a Simple Ethernet Cable?

Purchasing an ethernet can sometimes be unaffordable or expensive too.

Sometimes the predefined lengths are not according to what you are looking for.

If you know how to convert wifi to wired ethernet, then you can also enjoythe perks of a wired connection quite quickly even if you have a wireless connection.

What is an Ethernet Cable?

It is a standard network cable type that is used for the wired connection.

  • It belongs to the physical layer of the OSI model
  • This cable is used to connect devices in LAN.
  • They are physical cable and thus do not have such limitations.
  • Thus it links a networked enable device to another network enabled device.
  • For example, you can use it to connect your PC to the router.


It is used for connection purposed. It some benefit include:

  • Reliability
  • Speed
  • Data Security
  • Less packet dropping
  • Bandwidth
  • Noise immunity
  • Conceptually simple


  • Infrastructure requirements
  • Distance limitations
  • Expensive
  • Fault tolerant
  • Difficult to change
  • Difficult troubleshooting

Types of Ethernet Cable:

These are of two types:

  1. Straight Through Cables:

These are the standard cable used for most purposes.

They are also termed the patch cables.

  1. Crossover Cables:

They are used for connecting one computer to another computer or a computer to a device without going through a switch, hub or a router.

Color Order For Cross Over Cables:

The color order from left to right is

  1. white orange
  2. orange
  3. white green
  4. blue
  5. white blue
  6. green
  7. white brown
  8. brown

How to make an Ethernet Cable?

Making an ethernet cable is much simple and straightforward.

Things to Get Ready:

The things you will need in this making this cable are:

  • CAT5e or CAT6 cable
  • Rj45 Crimpable connectors for CAT-5e or CAT-6
  • Rj45 crimping tool

Process of Making the Cable:

Follow these steps to make a simple ethernet cable.

  1. Cut into the plastic sheath 2.5 cm (1 inch) from the cable end.
  2. You can do it with the crimple tool as it consists of a razor blade.
  3. Unwind the color.
  4. Pair the similar colors.
  5. Punch the wires holding between your fingers.
  6. Then straighten the cables.
  7. Do follow the color order.
  8. Then make straight cross across these 8 wires.
  9. You can use scissors to do this. Shorten them to 1/2 inch.
  10. Push all the eight unstripped wires into the connector.
  11. Make sure that the wires go all the way to the end.
  12. Also, check if there is any short wire.
  13. The blue plastic will remain outside the connector, and the cables should not extend more than 1/2 inch from the blue cut sleeve.

Cable Crimping:

  1. Place the connector into the crimper
  2. Punch down the handles tightly
  3. Then the copper slicing tabs present on the connector will pierce into the colored wires.
  4. A locking tab is also present to hold the blue plastic for a tight fit.
  5. After the cable is removed from the crimper, the end is ready to use.

Straight Through Cable:

To make a straight through cable, repeat all steps mentioned above.

Just the color order will be different in this case.

Testing Cable:

Before installing the cables, do test them.

A cable tester can be helpful for you in doing this.
