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.
Fiber optic internet isnât as widely available as DSL or cable internet service. Thatâs because the service doesnât use existing cable or telephone lines. Instead, new fiber optic cables need to be installed to offer service in a given area. These cables use light and tiny glass fibers to send and receive data.
