Copper Networks
Copper networks refer to telecommunications and data communication systems that use copper-based cabling, such as twisted-pair or coaxial cables, to transmit electrical signals. This technology underpins traditional wired infrastructure for telephone lines, Ethernet LANs, and broadband internet services like DSL. While largely superseded by fiber optics for high-speed long-distance links, copper remains prevalent in last-mile connections and legacy systems.
Developers should understand copper networks when working with legacy infrastructure, IoT deployments in older buildings, or troubleshooting connectivity issues in enterprise environments. Knowledge is essential for network engineers designing or maintaining local area networks (LANs), implementing Power over Ethernet (PoE), or integrating with existing telephony systems.
