How to Make Twisted Network Cable

Finished Twisted Network Cable

Twisted network cable is used to connect devices on a network to each other or to a router, switch, or hub. Twisted network cable is also known as Cat 5 cable. You can save time and money by making your own twisted network cable. Plus, you can cut the cable to the exact lengths you need instead of using the pre-made cable lengths available at most electronics stores. You can make your own twisted network cable in less than 10 minutes.

Things You'll Need

• Twisted network cable spool (no RJ45 ends)
• RJ45 Modular Jacks
• RJ45 Crimping Tool
• Scissors

Instructions

1. Using the crimping tool, insert ¾ inch of the twisted network cable end and remove the cable's coating. You can also use a pocket knife or scissors to strip the wire. Be sure not to cut the wires.

2. Untwist the wires so you have eight individual wires. Sort them in the following order from left to right: Orange White, Orange, Green White, Blue, Blue White, Green, Brown White, Brown.

3. Use the scissors to trim the edges of the wires so all wires are the same length.

4. Insert the wires into a modular jack. Insert with the hook side facing down or away from you. Be sure the wires are inserted completely to the top of the modular jack. Part of the coating should be inserted into the jack as well. If not, remove the wires and trim the wires slightly until part of the coating inserts into the modular jack.

5. Insert the modular jack into the RJ45 slot in the crimping tool. Press the tool together firmly until you hear a small snap. Pull out the modular jack and tug on the cable to be sure the wires are held firmly in place.

6. Measure out the length of cable you need and use scissors to cut the twisted network cable. Repeat the above process on the second end of the cable.

Tips & Warnings

• Double check the wire order before crimping the modular jack in place. Sometimes the wires cross during insertion. Twisted network cable supplies and tools can be purchased as a kit as some electronics and computer supply stores.

• Never crimp the modular jack until the wires are touching very top of the jack. Otherwise your cable will not work correctly.
