Which mechanism limits maximum data propagation speed in a copper Ethernet cable?

💡 Explanation

When signal frequency increases in copper Ethernet cable, the skin effect localizes current flow to the conductor's surface because of self-inductance, increasing effective resistance and signal attenuation, thus limiting propagation speed. Therefore skin effect dominates, rather than dielectric breakdown, reflections, or crosstalk, which have different frequency dependencies.
