Fiber Optic Cable Facts
"A relatively new technology with vast potential importance, fiber optics is the channeled transmission of light through hair-thin glass fibers."
[ Less expensive than copper cables
[ Raw material is silica sand
[ Less expensive to maintain If damaged, restoration time is faster (although more users are affected)
[ Backbone to the Information Superhighway
Information (data and voice) is transmitted through 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. Computers on the receiving end convert the light back into data or voice, so it can be used.

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 it can be used.
All of this seems to be a very "modern" concept, and the technology we use is. The concept though, was the idea of Alexander Graham Bell in the late 1800 's. He just didn 't have a dependable light source... some days the sun doesn 't shine! He thought of the idea that our voices could be transmitted by pulses of light. The people
