CCA - Copper Coated Aluminium : As copper prices increase, CCA offers a viable and cheaper alternative. Perfect for home and SOHO installations, these cheaper cable offer similar network performance as full copper. CCA Network cables are only suitable for standard networking. Aluminium has different properties than copper and are therefore not suitable for power applications (PoE - Power over Ethernet) or Extenders over Ethernet. We don't recommend CCA for business or industrial environments, as the cost saving is only small compared to cost of failure.
