Usually, you buy network cables ready made. A self-production can be very useful in some situations, e.g.
- If the cable channel is already so full that no cable plug fits through more.
- When the cable has to be routed through a tight hole in a wall.
- When the cable lengths are to be adjusted precisely.
The production is not as complicated and costly as it is often claimed. Here is a step-by-step guide on how to reliably and inexpensively assemble your cables. Our experiments have shown that a crimping tool in a simple design is sufficient.
- Network cable FTP (Foiled Twisted Pair) cat.5, price from approx. EUR 0.50 per meter
- RJ45 plug, shielded (with guide aid and anti-kink protection), as in the first picture, price from approx. EUR 1.20 per piece
- Crimping tool RJ45 (single version), price from approx. EUR 15,00
- Stripping knife, tweezers, needle nose pliers, small screwdriver
Steps to make an ethernet cable
- Push the protective and the sheath on the cable (forget it easy !!!). Then remove the outer cover of the cable to about 2 cm, bend wire (if available) to the rear.
- Unwrap and arrange veins: white / orange – orange – white / green – blue – white / blue – green – white / brown – brown.
There is also another color variant; It is only important that both cable plugs are assigned the same.
Push the leads into the introducer (possibly with tweezers) and cut straight.
- Hold the plug with the viewing window upwards and insert the wires together with the guiding aid all the way under the contacts (white/orange is on the left, brown on the right).
- Insert the plug into the crimping tool so that the gold contacts lie precisely under the crest of the pliers. Then press the pliers as far as they will go.
- The contacts are now pushed in and connected to the wires.
- Wire the cable to the connector shield.
- Use pointed pliers to bend the cable pull fuse.
- Using a screwdriver, bend the two inner side tabs inwards.
- Only the outer flags remain as a guide for the buckling protection.
- Slide on the cover. Finished.
The instructions apply in the details, of course, only for the plug type shown. The cable shown is a “patch cable.” All wires are looped 1: 1. It is used, for example, to connect a PC to a network socket or a hub. To connect two PCs, a “crossover cable” is needed in which individual lines are reversed.
