Optical Wireless Communication (OWC) ke mokhoa oa puisano oa optical oo mats'oao a fetisoang ho sebelisoa khanya e sa bonahaleng, ea infrared (IR), kapa ultraviolet (UV).
Litsamaiso tsa OWC tse sebetsang ka maqhubu a bonahalang (390 — 750 nm) hangata li bitsoa puisano ea leseli le bonahalang (VLC).Litsamaiso tsa VLC li nka monyetla ka li-diode tse hlahisang leseli (li-leds) 'me li khona ho otla ka lebelo le phahameng haholo ntle le litlamorao tse hlokomelehang tlhahisong ea mabone le leihlo la motho.VLC e ka sebelisoa lits'ebetsong tse fapaneng tse kenyelletsang LAN e se nang mohala, LAN ea motho ea se nang mohala le marang-rang a likoloi.Ka lehlakoreng le leng, lisebelisoa tsa OWC tse thehiloeng fatše, tse tsejoang hape e le lisebelisoa tsa sebaka sa mahala (FSO), li sebetsa haufi le maqhubu a infrared (750 — 1600 nm).Litsamaiso tsena hangata li sebelisa li-emitter tsa laser 'me li fana ka lihokelo tse hlakileng tsa protocol tse nang le litefiso tse phahameng tsa data (ke hore, 10 Gbit/s per wavelength) mme e fana ka tharollo e ka bang teng ho backhaul bottlenecks.Khahleho ea puisano ea ultraviolet (UVC) e boetse e ntse e eketseha ka lebaka la tsoelo-pele ea morao-rao mehloling e tiileng ea leseli/li-detectors tse sebetsang ho mahlaseli a letsatsi a foufetseng a UV (200 — 280 nm).Sehlopheng sena seo ho thoeng ke botebo ba ultraviolet, mahlaseli a letsatsi ha a na thuso boemong ba fatše, a etsa hore ho khonehe ho qaptjoa ha mochine oa ho bala photon o nang le mochine o pharaletseng o eketsang matla a amohelehang ntle le ho eketsa lerata le eketsehileng la mokokotlo.
Ka lilemo tse mashome, thahasello ea puisano ea optical wireless e lekanyelitsoe haholo-holo lits'ebetsong tsa sesole tse patehileng le lisebelisoa tsa sebaka se kenyeletsang li-intersatellite le lihokelo tsa sebaka se tebileng.Ho fihlela joale, ho kenella ha 'maraka oa OWC ka bongata ho fokotsoe, empa IrDA ke tharollo ea phetisetso ea nako e khuts'oane e atlehileng haholo.
Ho tloha ho optical interconnection ho lipotoloho tse kopantseng ho ea ho lihokelo tsa ka ntle tsa li-interbuilding ho ea puisanong ea sathelaete, mefuta e fapaneng ea puisano e se nang mohala e ka sebelisoa mefuteng e mengata ea puisano.
Puisano ea waelese ea Optical e ka aroloa ka mekhahlelo e mehlano ho latela mefuta ea phetiso:
