Fiber optic transmitters are devices that include an LED or laser source, and signal conditioning electronics, to inject a signal into fiber

Fiber optic receivers are instruments that convert light into electrical signals.

Fiber optic transceivers include both a transmitter and a receiver in the same component

Lasers are devices that produce intense beams of monochromatic, coherent radiation.

Optical triangulation position sensors use reflected waves to pinpoint position and displacement.

Diode lasers use light-emitting diodes to produce stimulated emissions in the form of coherent light output.

Optical switches are optoelectric devices, consisting of a light source and a detector that produces a switched output.
