do you know What were fiber optic cables designed for? They were designed for the transmission of light.Light has unusual properties.. it can carry sound, light energy, and just about anything a wire can do except electrictity.The difference is that it does it much easier and with greater efficiency.Picture a ping pong ball in a long pipe. You write something on it and throw it in the pipe. It will bounce on the walls and roll around but eventually it must come out the other end.Electrons are not as easy to please. When they start hitting and bouncing they heat up… some of their energy is lost in that heat. Some may be lost in electo-magnitic disturbance and so on. So you never quite get ‘out’ what you put in. Plus… you can only send electrical current.Fiber optics can send several things in that light beam…(plus they make dandy toys).Other plus factors..Wires break down and oxidize ever see old brittle wires or wires with the insullation falling off.Optic cables are pretty much inert and, while they may have a protective insulator, they can work just fine as the bare cable.
