The fiber optic cable carrying the signals are digital data signals as pulses of light modulated.

The fiber optic cable carrying the signals are digital data signals as pulses of light modulated. This is a relatively safe way to send data because, unlike the copper wires that carry data as electronic signals, optical fiber cables carry electrical impulse The fiber optic cable suitable for transmitting data at very high speeds and large capacities due to lack of signal attenuation and its purity. An optical fiber consists of an extremely thin glass cylinder, called the nucleus, covered by a concentric layer of glass, known as a coating. The fibers are made of plastic sometimes. Plastic is easier to install, but can not carry pulses of light at distances as great as the glass. Because glass fibers pass signals in one direction, a cable has two wires in separate envelopes. A thread transmits and the other receives.
