The material of the network cable has a crucial impact on the performance of the network.BC \\uff08Oxygen free copper\\uff09network cable is the mainstream choice for home and commercial users due to its excellent conductivity and durability; CCA\\uff08copper-clad aluminum\\uff09network cable is suitable for scenarios with limited budgets due to its high cost-effectiveness. There are obvious differences between pure copper network cable and copper-clad aluminum network cable in terms of material, performance, price, etc.
In terms of conductivity, BC network cable has excellent conductivity and low resistance; signal transmission loss is small, especially in long-distance transmission; pure copper network cable can better support high-bandwidth and high-speed network connections (such as Gigabit or 10 Gigabit networks). The conductivity of aluminum is much lower than that of copper. Although the surface copper material improves certain performance, the overall conductivity is not as good as pure copper. The signal attenuation is obvious in long-distance transmission. It is not suitable for wiring over 50 meters. CCA network cable is suitable for scenarios with low requirements for network performance.
In terms of durability, BC network cable has strong antioxidant ability and is not easy to corrode. After long-term use, the performance remains stable and the service life is long; while CCA is easily oxidized, resulting in increased contact resistance and performance degradation over time. In addition, it has high environmental requirements and is easily oxidized in humid environments.
From the perspective of mechanical strength, pure copper network cables have high mechanical strength and strong bending resistance. They are not easily damaged by stretching or extrusion.Copper-clad aluminum network cables have weak bending and stretching resistance due to the soft aluminum material. They are easy to break during wiring construction, reducing reliability.
