Koppartrådsnät

Koppartrådsnät, often translated as copper wire network, refers to the traditional telecommunications infrastructure that uses copper wires to transmit signals. This network was the backbone of early telephone systems and later adapted for internet access through technologies like DSL (Digital Subscriber Line). The copper wires, typically made of copper, carry electrical signals that represent voice or data. These networks have been instrumental in connecting homes and businesses for over a century.

The advantages of copper wire networks include their widespread existing infrastructure, making them relatively easy to deploy in established areas. They also offer a cost-effective solution for basic voice communication and lower-speed internet services. However, copper's limitations become apparent with increasing distances and the demand for higher bandwidth. Signal degradation over long distances can lead to slower speeds and reduced reliability.

Modern telecommunications are increasingly transitioning to fiber optic networks, which use light signals transmitted through glass or plastic fibers. Fiber optics offer significantly higher bandwidth, faster speeds, and greater immunity to electromagnetic interference compared to copper. Despite the rise of fiber, copper wire networks remain in use in many parts of the world, particularly for providing basic telephone services and for "last mile" connectivity where fiber deployment is not yet complete or economically feasible.
