There are many copper core materials for network cables, such as iron-aluminum, copper-clad aluminum, copper-clad silver, all-copper, oxygen-free copper and other materials. The main materials used are copper-clad silver, all-copper (bronze) and oxygen-free copper.

        The copper-clad silver network cable is made of imported aluminum. In a single environment, it can effectively transmit 180 meters, but if it is a complex wiring environment like an Internet cafe, the transmission distance is not so long. The disadvantage of copper-clad silver is that the oxidation resistance is not high. , the service life is not long.

        The main material of the all-copper network cable is bronze, which can transmit about 90-100 meters in an ordinary network. It has high oxidation resistance, high resistance and poor transmission.

       The main material of oxygen-free copper network cable is high-purity oxygen-free copper, and the transmission distance can reach about 120 meters. It is suitable for medium and large-scale integrated wiring projects, with low resistance, high oxidation resistance and good transmission.

       The 4-core network cable generally only has copper-clad aluminum and oxygen-free copper. The copper-clad aluminum network cable can also transmit to about 160 meters, and the oxidation resistance is not high. The oxygen-free copper has high oxidation resistance and can transmit to about 100 meters. The network cable is not as stable as the oxygen-free copper network cable.
