ʻO ke Kamaʻilio Uila ʻOpikala (OWC) kahi ʻano kamaʻilio optical kahi e hoʻouna ʻia ai nā hōʻailona me ka hoʻohana ʻana i ke kukui ʻike maka ʻole ʻia, infrared (IR), a i ʻole ultraviolet (UV).
ʻO nā ʻōnaehana OWC e hana ana ma nā nalu ʻike ʻia (390 — 750 nm) ua kapa pinepine ʻia ʻo ke kamaʻilio mālamalama ʻike ʻia (VLC). Hoʻohana nā ʻōnaehana VLC i nā diode hoʻokuʻu mālamalama (leds) a hiki ke pulse i nā wikiwiki kiʻekiʻe loa me ka ʻole o nā hopena i ʻike ʻia ma ka puka kukui a me ka maka kanaka. Hiki ke hoʻohana ʻia ʻo VLC ma nā ʻano noi like ʻole me ka LAN uea ʻole, ka LAN pilikino uea ʻole a me ka pūnaewele kaʻa. Ma ka ʻaoʻao ʻē aʻe, ʻo nā ʻōnaehana OWC point-to-point ma ka honua, i ʻike ʻia hoʻi he mau ʻōnaehana optics ākea manuahi (FSO), e hana ana ma nā alapine kokoke i ka infrared (750 — 1600 nm). Hoʻohana pinepine kēia mau ʻōnaehana i nā mea hoʻoheheʻe laser a hāʻawi i nā loulou aniani protocol kūpono me nā helu ʻikepili kiʻekiʻe (ʻo ia hoʻi 10 Gbit/s no kēlā me kēia nalu) a hāʻawi i kahi hopena kūpono i nā bottlenecks backhaul. Ke ulu nei ka hoihoi i ka kamaʻilio ultraviolet (UVC) ma muli o nā holomua hou i nā kumu kukui/mea ʻike paʻa e hana ana ma ka spectrum UV makapō lā (200 — 280 nm). Ma kēia mea i kapa ʻia ʻo ka pūʻulu ultraviolet hohonu, he mea liʻiliʻi ʻole ka hoʻomehana lā ma ka pae honua, e hiki ai ke hoʻolālā ʻia kahi mea ʻike helu photon me kahi mea loaʻa ākea e hoʻonui ai i ka ikehu i loaʻa me ka ʻole o ka hoʻohui ʻana i ka walaʻau hope hou.
No nā makahiki he ʻumi, ua kaupalena ʻia ka hoihoi i nā kamaʻilio uea ʻole optical i nā noi koa huna a me nā noi lewa e pili ana i nā loulou intersatellite a me nā lewa hohonu. A hiki i kēia lā, ua kaupalena ʻia ke komo ʻana o OWC i ka mākeke nui, akā he hopena hoʻoili pōkole uea ʻole holomua loa ʻo IrDA.
Mai ka pilina optical i loko o nā kaapuni i hoʻohui ʻia a i nā loulou kūkulu waho a hiki i nā kamaʻilio ukali, hiki ke hoʻohana ʻia nā ʻano like ʻole o ke kamaʻilio uea ʻole optical i nā ʻano hana kamaʻilio like ʻole.
Hiki ke hoʻokaʻawale ʻia ke kamaʻilio uea ʻole optical i ʻelima mau ʻāpana e like me ka laulā hoʻoili:
1. Nā mamao pōkole loa
Ke kamaʻilio ʻana o Interchip i loko o nā pūʻolo multi-chip i hoʻopaʻa ʻia a hoʻopaʻa paʻa ʻia.
2. Nā mamao pōkole
Ma ke ʻano maʻamau IEEE 802.15.7, ke kamaʻilio ʻana ma lalo o ka wai ma lalo o nā polokalamu Wireless Body Local Area Network (WBAN) a me nā polokalamu Wireless Personal Local Area Network (WPAN).
3. Pae waena
ʻO ka IR o loko a me ke kamaʻilio ʻana o ka mālamalama ʻike ʻia (VLC) no nā pūnaewele wahi kūloko uea ʻole (WLans) a me ke kamaʻilio ʻana o ke kaʻa-i-ke kaʻa a me ke kaʻa-i-ke kahua.
KaʻAnuʻu Hana 4: Mamao
ʻO ka pilina ma waena o nā hale, i ʻike ʻia hoʻi ʻo ke kamaʻilio optical ākea manuahi (FSO).
5. Ka mamao keu
Ke kamaʻilio laser ma ka lewa, ʻoi aku hoʻi no nā pilina ma waena o nā satelite a me ka hoʻokumu ʻana o nā hōkū hōkū satelite.
