A fiber optic transceiver, often simply referred to as an "optical transceiver," is a device used in fiber optic communications to transmit and receive data over optical fibers. It integrates both a...

A slab-shaped, very low profile package for electronic components; often used when printed circuit boards must be closely stacked together.

An optical switch that controls conduction paths into and out of a junction in fiber optic and integrated optical circuits.

A type of internal photonic connection in an integrated circuit in which a holographic grating is used to focus light at points on a silicon chip, maximizing the speed of signal propagation.
