.... the fiber digitally by the use of high speed LASERs (Light Amplification through the Simulated Emission of Radiation) or LEDs (Light Emitting Diodes). Each of these methods create a highly focused beam of light that is cycled on and off at very high speeds. Computers at the transmitting end convert data or voice into "bits" of information. The information is then sent through the fiber by the presence, or lack, of light. So, all of the data is sent light pulses. Computers on the receiving end convert the light back into data or voice, so ....
