Q: When would I use fiber optic cable instead of copper cable?

A: Fiber, due to its ability to carry significantly more data than copper, is typically used to link switches between telecommunications rooms. In this capacity it would act as a data backbone between rooms. Fiber is also used for longer runs. For example, Category 6 cable has a maximum installed length of 295 feet, regardless of the application running over it. Multimode fiber can support gigabit Ethernet up to 1,000 meters and Singlemode can support it up to 5,000 meters. As you can see, fiber can carry a signal much farther than copper.
