• Freedom from EMI — Fiber optics are immune to electromagnetic interference (EMI), and they emit no radiation themselves to cause other interference. In 1880, Alexander Graham Bell conducted an experiment where he made a phone call using natural light (sunlight) to convert his voice into light via a “photophone. ” This light was transmitted approximately 700 ft. • Lighter and Smaller — Fiber weighs less and needs less space than. Fiber optics (optical fibers) are long, thin strands of very pure glass about the size of a human hair.
