Netwerkkabel.eu sells cables made of CCA and cables made of 100% copper. What is the difference and when do you choose which?

CCA
CCA means 'Copper Clad Aluminum'. This means that the cores in the cable are made of aluminum with a layer of copper over it. These cables are suitable for a length of up to 50 meters. CCA cables are mainly suitable for temporary solutions.

100% copper
A 100% copper network cable therefore consists of... 100% copper cores. These cables are suitable for a length of up to 100 meters. If you want to use Power over Ethernet (network power), it is best to use 100% copper cables.

Which cable is suitable?

It's quite simple: in the long term (several years) and for better performance over longer distances, a 100% copper cable is most suitable.

• With CCA cables, performance decreases from 10 meters and they are certainly not suitable for lengths longer than 50 meters. 100% copper network cables perform well up to 100 meters.
• Aluminum is relatively stiff, which means there is a (much) greater chance of breakage than with 100% copper cables.
• Network cables of 100% are suitable for PoE applications (power over ethernet), CCA cables are not.
