Re: Fiber > Copper

Um.. So light is now digital? News to me.

So the sun has been giving us digital information all this time? Someone better start decoding it.

How Fiber Optic Cables Work
The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Radio over fiber would be analog which I don't have...
