Which statement describes fiber optic cables in networking?

• A. They are cheap and support short distances.
• B. They are wireless and inexpensive.
• C. They enable long-distance transmission but are expensive.
• D. They are used only for local connections.

Answer: (C)

Fiber optic cables transmit data as light through glass or plastic fibers, which minimizes signal loss and makes them able to carry signals over very long distances with high bandwidth. That long-distance capability comes with higher costs today due to the need for specialized equipment (transceivers, connectors, splicing) and careful installation. So, they enable long-distance transmission but are expensive. They aren’t wireless and aren’t limited to local connections; they are commonly used for backbone and long-haul networking where distance and speed matter.
