Optical fiber

Optical Fibers are glass fibers usually about 120 micrometers in diameter that are used to deliver wave signals in the form of pulses of light over distances up to 50 km without the using repeaters. These wave signals may be coded voice communications or computer data. Fiber optic communications is dependent on the principle that light in a glass medium can carry more information over longer distances than electrical signals can carry in a copper or coaxial …showed first 75 words of 1144 total…
