The fiber optic technology has been developed mostly for use in communication. fiber-optic communication is transmitting information from one place to another by sending pulses of light through an optical fiber. a technology that uses glass or threads to transmit data. a basic fiber optic system consists of a transmitting device that converts an electrical signal into a light signal, an optical fiber cable that carries the light, and a receiver that accepts the light signal and converts it back into an electrical signal. fiber optics is a particularly popular technology for local area networks.
Fiber Optic Transmitters and Receivers
- Transmitters: – The most commonly used optical transmitters are semiconductor devices such as light-emitting diodes (LEDs) and laser diodes.
- Receivers: – The main component of an optical receiver is a photodetector, which converts light into electricity using the photoelectric effect.
Fiber optics are long, thin strands of very pure glass about the size of a human hair. they are arranged in bundles called optical cables and used to transmit signals over long distances.
Optical fiber types
There are two major categories:
- Step index fiber optic cabling
- Graded index fiber optic cabling
