Optic fiberisa light conduction chida chomwe chimagwiritsa ntchito mfundo yowunikira kwathunthu mu fiber yopangidwa ndi galasi kapena pulasitiki.
Ulusi wa Optical bare fiber nthawi zambiri umagawidwa m'magulu atatu: pachimake, chotchingira ndi zokutira.
Pakatikati pa magalasi owoneka bwino amapangidwa ndi magalasi amitundu yosiyanasiyana, okhala ndi magalasi apamwamba a refractive index (germanium-doped silicon dioxide) pakatikati ndi cholozera chotsika cha silicon glass cladding (choyera silicon dioxide) pakati. Kuwala kumawomberedwa mu CHIKWANGWANI pazochitika zinazake, ndipo kutulutsa kwathunthu kumachitika pakati pa ulusi ndi kutsekeka (chifukwa index ya refractive ya cladding ndiyotsika pang'ono kuposa pachimake), kotero kuti imatha kufalikira kudzera mu ulusi. Ntchito yaikulu ya chophimba chophimba ndi kuteteza CHIKWANGWANI kuchokera kunja kuwonongeka, ndipo nthawi yomweyo kuwonjezera kusinthasintha kwa CHIKWANGWANI. Monga tanena kale, pachimake ndi zomangira zimapangidwa ndi magalasi, omwe sangathe kupindika komanso osalimba, ndipo kugwiritsa ntchito chophimba kumateteza ndikuwonjezera moyo wa ulusi.
Zomwe zili pamwambazi ndi "fiber structure" zomwe zimabweretsedwa Zithunzi za HDV PhoelekitironiMalingaliro a kampani Technology LTD.Kampani yathu ndi zida zapadera zowonera maukonde monga opanga zazikulu zopanga, zida zokhudzana ndi maukonde okhudzana chimakwirira mndandanda wa OLT, mndandanda wa ONU, mndandanda wakusintha, mndandanda wama module ndi zina zotero, kulandiridwa kuti mumvetse.
