Which of the following is an advantage of a fiber network?

Choosing higher speeds compared to copper as an advantage of a fiber network is accurate because fiber optic cables facilitate data transmission at much greater speeds than traditional copper cables. This is due to the way fiber optics transmit data using light signals, which can carry more information over long distances without degradation.

Copper cables, on the other hand, are limited by electromagnetic interference and have higher attenuation, meaning the signal loses strength over distance. Hence, fiber optic networks can support much faster internet speeds and higher bandwidth, appealing for applications demanding high data rates, such as video streaming and large file transfers.

The other options may not accurately reflect the characteristics of fiber networks. For instance, while installation costs can vary, fiber networks often have higher installation costs due to the need for specialized equipment and expertise. Additionally, fiber optics currently have limited availability in comparison to DSL, particularly in underserved areas. The ease of installation for fiber is also typically considered more complex than copper installations, since fiber requires specific handling and installation techniques.
