You are able to transmit information over long distances Basic systems send information over a distance of 5 km to 80 km. Fiber optics on the other hand transmit information digitally where the information is repeated and regenerated indefinitely.
This makes it possible for you to transmit the information to almost any distance that you would like. Repetition and regeneration of the signal is made possible by the electro-optical repeater or an erbium doped fiber amplifier.
