Fiber Optic is the medium used in the best data networks. A very thin filament of transparent material, glass or plastic materials, through which pulses of light are sent inside, that represent the data to be transmitted. The main benefits that Fiber Optic brings to users are the high speed (up to 1000Mb) in downloading and uploading data and content to the Internet. Unlike ADSL, Fiber Optics is much more resilient in unfavorable conditions, safer and more reliable, as the fibers do not lose light thanks to total reflection.
