FiOS (Fiber Optic Service) is an end-to-end optical fiber telecommunications network that runs from a central point directly to individual buildings.
What you need to know.
It is the best available option for transmitting data, offering significant speed and quality advantages over coax (traditionally used by cable companies) and twisted copper (traditionally used by phone companies).
FiOS is pure fiber end-to-end, so your data doesn’t have to tap the brakes and downshift into different transmission methods. The results are 10mb/s download and 2mb/s upload (the minimum speed offered) with up to 20mb/s download and upload available.
Compare that with the 3mb/s download and 1.5mb/s upload speeds (sustained) of most cable and DSL connections
