Connecting the World
Social media, low cost telephone calls, video conferencing with family and friends – these are three examples of how the internet allows people around the world to feel connected in a way that has never before been possible in history.
What are fiber optics?
Optical fibers are extremely thin, flexible, transparent fiber made of silica or plastic. These hair-like fibers transmit light signals from one end to the other, and over long distances when conjoined end-to-end. Most commonly used in telecommunications, the use of light in fiber optics has revolutionized the way humans interact in the 21st century.
Why do we use fiber optics?
Unlike wire cables, optical fibers permit transmission over long distances at high bandwidths. Fibers are also used because signals travel through them with less loss than in metal wires, and they are unaffected by electromagnetic interference.
