Compared to copper, fiber-optic cables can transmit signals over which of the following distances?

Fiber-optic cables are designed to transmit data using light signals, which enables them to cover much longer distances compared to copper cables, which transmit electrical signals. The key factors contributing to this difference include lower attenuation and reduced signal degradation in fiber optics, allowing for high-speed data transmission over extensive networks, often exceeding distances of several kilometers without the need for repeaters.

In contrast, copper cables, which include twisted pairs and coaxial cables, tend to experience higher levels of resistance and interference over long distances, limiting their effective transmission range. Consequently, for applications requiring long-distance communication, fiber-optic technology is the preferred choice due to its superior performance in maintaining signal integrity and speed.
