Fiber optic receivers use positive-negative junctions PN , positive-intrinsic negative PIN photodiodes, or avalanche photodiodes APD as optical detectors. The incoming light signal is sent by a fiber optic transmitter or transceiver and travels along single-mode or multi-mode optical cable, depending on device capabilities. A data demodulator converts the light signal back into its original electrical form.
In more complex fiber optic systems, wavelength division multiplexing WDM components are also used. The Engineering SpecSearch database allows industrial buyers to select products by semiconductor type and photodiode type. Two types of semiconductors are used in fiber optic receivers. Typically, fiber optic receivers include a removable adaptor for connections to other devices. When using Engineering to source products, buyers should specify these parameters for fiber optic receiver performance. Info - Parts of a Fiber Optic Link.
