OOO (Optical-Optical-Optical)

A device that is purely optical in nature, rather than having electri-

cal or electronic as well as optical components. The repeaters used in fiber optic transmission systems (FOTS), for example, are Optical-Electrical-Optical (OEO). Optical switches used in wavelength division multiplexed (WDM) transmission systems sometimes are purely optical. See also FOTS, OEO, optical, and WDM.
