Optical telegraphThe optical telegraph preceded the electrical telegraph. It was faster than riding couriers for bringing a message over long distances. Types of optical telegraph are the semaphore, ship flags, smoke signals, and beacons. The distance that an optical tele	Optical fiberAn optical fiber in American English or fibre in British English is a transparent thin fiber for transmitting light.
