Unxibelelwano lwe-Optical Wireless (OWC) luhlobo lonxibelelwano lwe-optical apho imiqondiso ihanjiswa kusetyenziswa ukukhanya okungabonakaliyo, i-infrared (IR), okanye i-ultraviolet (UV) ukukhanya.
Iinkqubo ze-OWC ezisebenza kwii-wavelengths ezibonakalayo (390 — 750 nm) zidla ngokubizwa ngokuba lunxibelelwano lokukhanya olubonakalayo (VLC). Iinkqubo ze-VLC zithatha ithuba le-diode ezikhupha ukukhanya (ii-leds) kwaye zinokubetha ngesantya esiphezulu ngaphandle kwemiphumo ebonakalayo ekuphumeni kokukhanya kunye neliso lomntu. I-VLC ingasetyenziswa kuluhlu olubanzi lwezicelo ezibandakanya i-LAN engenazingcingo, i-LAN yomntu engenazingcingo kunye nothungelwano lwezithuthi. Ngakolunye uhlangothi, iinkqubo ze-OWC ezisekelwe kumhlaba, ezaziwa ngokuba ziinkqubo ze-free space optics (FSO), zisebenza kwii-frequencies ezikufutshane ne-infrared (750 - 1600 nm). Ezi nkqubo ngokuqhelekileyo zisebenzisa i-laser emitters kwaye zibonelela ngexabiso elisebenzayo i-protocol links transparent kunye namazinga aphezulu edatha (okt 10 Gbit / s nge-wavelength nganye) kwaye zibonelela ngesisombululo esinokubakho kwi-backhaul bottlenecks. Umdla wonxibelelwano lwe-ultraviolet (UVC) nawo uyakhula ngenxa yenkqubela phambili yamva nje kwimithombo yokukhanya eqinileyo/ii-detectors ezisebenza kwi-sun-blind UV spectrum (200 — 280 nm). Kule nto ebizwa ngokuba yi-deep ultraviolet band, i-radiation yelanga ayinanto kwinqanaba eliphantsi, okwenza kube lula ukuyila i-photon-counter detector kunye ne-wide-field receiver eyandisa amandla afunyenweyo ngaphandle kokongeza ingxolo eyongezelelweyo yangasemva.
Kangangamashumi eminyaka, umdla kunxibelelwano olungenazingcingo luthintelwe ikakhulu kwizicelo zasemkhosini ezifihlakeleyo kunye nezicelo zendawo ezibandakanya i-intersatellite kunye namakhonkco esithuba esinzulu. Ukuza kuthi ga ngoku, ukungena kwimakethi enkulu ye-OWC kuthintelwe, kodwa i-IrDA sisisombululo esiphumeleleyo sothumelo loluhlu olufutshane lwamacingo.
Ukusuka kwi-optical interconnection kwiisekethe ezidibeneyo ukuya kwi-outdoor interbuilding links ukuya kunxibelelwano lwesathelayithi, ukwahluka konxibelelwano olungenazingcingo olubonakalayo lunokusetyenziswa kwiintlobo ngeentlobo zezicelo zonxibelelwano.
Unxibelelwano olungenazingcingo lwe-Optical lunokwahlulwa lube ziindidi ezintlanu ngokoluhlu lothumelo:
1. Imigama emifutshane kakhulu
Unxibelelwano lwe-Interchip kwiipakethe ezipakishweyo nezipakishwe ngokuqinileyo ngeetshiphu ezininzi.
2. Imigama emifutshane
Kumgangatho we-IEEE 802.15.7, unxibelelwano lwangaphantsi kwamanzi phantsi kwe-wireless Body Local Area Network (WBAN) kunye ne-wireless Personal Local Area Network (WPAN) izicelo.
3. Uluhlu oluphakathi
I-IR yangaphakathi kunye nonxibelelwano olukhanyayo olubonakalayo (VLC) kuthungelwano lwengingqi olungenacingo (i-WLans) kunye nonxibelelwano lwesithuthi ukuya kwisithuthi kunye nesithuthi ukuya kwi-infrastructure.
Inyathelo lesi-4: Ukude
Unxibelelwano lwe-Interbuilding, olukwabizwa ngokuba yi-free space optical communication (FSO).
5. Umgama owongezelelweyo
Unxibelelwano ngeLaser emajukujukwini, ngakumbi kunxibelelwano phakathi kwesathelayithi kunye nokusekwa kweenkwenkwezi zesathelayithi.
