What is a main advantage of using fiber cabling over copper cabling in networking?

The main advantage of using fiber cabling over copper cabling in networking is the capacity for longer distances without data loss. Fiber optic cables use light signals to transmit data, which allows them to maintain signal integrity over much greater distances compared to copper cables, which rely on electrical signals. Signal degradation in copper occurs more quickly, especially over long distances, leading to issues such as increased latency and reduced bandwidth.

In contrast, fiber optics can effectively transmit data over several kilometers without significant loss in signal quality, making them an excellent choice for backbone connections in networks, inter-building communications, and other applications where long runs of cabling are necessary. This characteristic is crucial in modern networking environments where high-speed data transfer and minimal latency are essential for performance. While other factors such as cost, flexibility, and ease of installation may be relevant in deciding between fiber and copper, the capability of fiber to support long-distance communication without data degradation stands out as a significant advantage.
