What is the main benefit of using fiber optics over copper cables?

The main benefit of using fiber optics over copper cables lies in their higher bandwidth and faster transmission speeds. Fiber optic cables utilize light signals transmitted through glass or plastic fibers, which can carry vast amounts of data over long distances with minimal loss. This capability allows for significantly higher data rates, making fiber optics ideal for high-speed internet and large data transfers compared to copper cables, which are limited by electrical resistance and signal attenuation over distance.

Additionally, fiber optics can support multiple wavelengths of light, enabling efficient data transmission and the capability to carry multiple signals simultaneously without interference. This multi-wavelength functionality contributes further to their higher capacity and improves overall performance in data networks, especially in environments where speed and bandwidth are critical.

While other options like lower installation costs, resistance to environmental factors, and lifespan are relevant considerations, they do not capture the primary advantage that fiber optics offer regarding data transmission capabilities.
