What is one potential benefit of having a 100% fiber-optic network?

A 100% fiber-optic network offers the significant advantage of higher transmission speeds. This is due to the ability of fiber-optic cables to carry data using light signals, which allows for much greater bandwidth compared to traditional copper cables. Fiber-optic technology can transmit data over long distances with minimal signal degradation and interference. Consequently, this capability supports the increasing demand for high-speed internet, accommodating more users and data-heavy applications, thus enhancing overall network performance.

The other options, while related to network design and implementation, do not capture the primary advantage of fiber optics as effectively as increased transmission speeds. For instance, initial installation costs can often be higher for fiber than for other technologies, the use of existing infrastructure can be limited depending on the situation, and while maintenance is typically lower for fiber, this is not as compelling a benefit as the speed advantage that fiber optics uniquely provides.
