Like any Internet service, fiber optic Internet download speeds depend on your connection. Not all fiber services are created equal, much like broadband. Fiber is not distance sensitive like copper based services, but speeds can vary. Fiber is faster than average broadband speeds in the USA.
Although fiber optic functions through the use of a cable, the contents inside the cable are what differentiate it from cable Internet. Fiber optic consists of glass cables which is the reason it is also referred to as an optical cable.epending upon the type of glass that is used during cable construction, the speed of the connection may fluctuate, but still produces a very fast connection speed. The typical speed for a fiber optic Internet connection will range between 150 Mbps (megabits per second) and 500 Mbps.
