Solid Copper vs CCA Cable: Which Should You Choose?

When selecting Ethernet cable, one of the most important decisions is choosing between solid bare copper conductors and copper-clad aluminum (CCA).

Solid copper cables provide lower resistance, better signal transmission, and improved durability. They are widely recommended for professional network installations and Power over Ethernet (PoE) applications.

CCA cables use an aluminum core coated with copper. While they are less expensive, they generally offer higher resistance and reduced performance compared to solid copper cables.

Benefits of Solid Copper:

• Better signal quality
• Lower voltage drop
• Improved PoE performance
• Greater durability
• Compliance with industry standards

For long-term reliability and professional installations, solid copper Ethernet cables remain the preferred choice.
