I-Fiber optics, futhi i-spelled fibre optics, iisayensikweukudlulisaidatha, izwi, nemifanekiso ngokudlula kokukhanya emicupheni emincane, ekhanyelayo.Kuezokuxhumana, ubuchwepheshe be-fiber optic cishe sebuthathe indawoithusiucingo phakathiindlela ende ucingoimigqa, futhi isetshenziselwa ukuxhumanisaamakhompyuthangaphakathiamanethiwekhi wendawo.I-Fiberopticsfuthi isisekelo se-fiberscopes esetshenziswa ekuhloleni izingxenye zangaphakathi zomzimba (i-endoscopy) noma ukuhlola ingaphakathi lemikhiqizo yesakhiwo.

Indawo eyisisekelo ye-fiber optics iyi-fiber enezinwele ezacile ngezinye izikhathi eyenziwa ngayoipulasitikikodwa izikhathi eziningiingilazi.I-glass optical fiber evamile inobubanzi obuyi-125 micrometres (μm), noma 0.125 mm (0.005 intshi).Lokhu empeleni ububanzi be-cladding, noma ungqimba olubonisayo lwangaphandle.I-core, noma isilinda sokudlulisa ngaphakathi, singase sibe nobubanzi obuncane obungu-10μm.Ngenqubo eyaziwa ngokuthiukucabangisisa kwangaphakathi okuphelele,ukukhanyaimisebe ikhanya ku-fiber cansabalalisangaphakathi kwamabanga amade ngokuncishiswa okuncane ngokuphawulekayo, noma ukuncipha kokuqina.Izinga lokuncipha ngebanga liyahlukahluka kuye ngobude begagasi bokukhanya kanye neukwakhekakwe-fiber.

Lapho imicu yengilazi yedizayini ewumgogodla/yokuvala yethulwa ekuqaleni kwawo-1950, ukuba khona kokungcola kwakhawulela ukuqashwa kwabo ubude obufushane obanele be-endoscopy.Ngo-1966, onjiniyela bakagesiCharles KaonoGeorge Hockham, abasebenza eNgilandi, basikisela ukusebenzisa imicu ukuzeezokuxhumana, futhi phakathi neminyaka engamashumi amabilii-silicaimicu yengilazi yayikhiqizwa ngobumsulwa obanele ukuthii-infraredizimpawu zokukhanya zingahamba kuzo amakhilomitha angu-100 (60 miles) noma ngaphezulu ngaphandle kokuba zithuthukiswe abantu abaphindayo.Ngo-2009 uKao waklonyeliswa ngendondoUmklomelo weNobelkuPhysics ngomsebenzi wakhe.Imicu yepulasitiki, ngokuvamile eyenziwe nge-polymethylmethacrylate,i-polystyrene, nomai-polycarbonate, ashibhile ukukhiqiza futhi avumelana nezimo kunemicu yengilazi, kodwa ukuncishiswa kwawo okukhulu kokukhanya kukhawulela ukusetshenziswa kwawo ezixhumanisini ezimfushane kakhulu ngaphakathi kwezakhiwo nomaizimoto.

I-Optical telecommunication ivamise ukuqhutshwa ngei-infraredukukhanya kububanzi be-wavelength obungu-0.8–0.9 μm noma 1.3–1.6 μm—amaza amaza akhiqizwa ngokuphumelelayoama-diode akhipha ukukhanyanomai-semiconductor ama-laserfuthi lokho kuncipha kancane emicu yengilazi.Ukuhlolwa kwe-fiberscope ku-endoscopy noma embonini kwenziwa ngamaza abonakalayo, inqwaba yemicu isetshenziselwakhanyisaindawo ehloliwe enokukhanya nenye inyanda esebenza njengendeilensiyokudlulisa isithombe ku-iso lomuntunoma ikhamera yevidiyo.
