Netwerkkabel.eu sells cables made out of CCA and 100% copper.
What is the difference?
CCA means 'Copper Clad Aluminium'. The wires are made out of aluminium coated with copper. These cables are suitable for a length up tot 50 meters. It is mainly suited for temporarily solutions.
So, naturally, the 100% copper cable consist of... 100% copper wires. They are suitable for a length up to 100 meters. When you want to use Power over Ethernet, you can use 100% copper wires at best.
Which cable should I use?
It is relatively easy: when in need of a better performance on longer terms (several years) over longer distances, a 100% cable is most suitable.
- When using a CCA cable, its performance can start decreasing at a distance of 10 meters, and they are not suitable at all for distances over 50 meters. Cables made out of 100% copper can perform well up to distances of 100 meters.
- Aluminum is relatively rigid. Because of this, chance of defects are (much) bigger compared to 100% copper cables.
- Cables made of 100% copper are suitable for PoE (power over ethernet) adjustments, whereas CCA cables are not.
