Ulusi wa Plastic Optical (POF) (kapena Pmma Fiber) ndi ulusi wowoneka bwino womwe umapangidwa kuchokera ku polima. Mofanana ndi galasi kuwala kwa fiber, POF imatumiza kuwala (powunikira kapena deta) kupyolera pakati pa fiber. Ubwino wake waukulu pamagalasi, mbali ina yofanana, ndikulimba kwake pansi pa kupinda ndi kutambasula. Poyerekeza ndi magalasi opangira magalasi, mtengo wa PMMA umakhala wotsika kwambiri.
Pachikhalidwe, PMMA (acrylic) imakhala pachimake (96% ya gawo la mtanda mu ulusi wa 1mm m'mimba mwake), ndipo ma polima opangidwa ndi fluorinated ndi zinthu zophimba. Kuyambira kumapeto kwa zaka za m'ma 1990s ulusi wapamwamba kwambiri wa index index (GI-POF) wotengera amorphous fluoropolymer (poly(perfluoro-butenylvinyl ether), CYTOP) wayamba kuwonekera pamsika. Ulusi wowoneka bwino wa polima nthawi zambiri amapangidwa pogwiritsa ntchito extrusion, mosiyana ndi njira yokoka yomwe imagwiritsidwa ntchito ngati ulusi wagalasi.
CHIKWANGWANI cha PMMA chimatchedwa [consumer” optical fiber chifukwa ulusi ndi maulalo olumikizana nawo, zolumikizira, ndi kuyika zonse ndizotsika mtengo. Chifukwa cha kufooketsa ndi kupotoza kwa ulusi wa PMMA, amagwiritsidwa ntchito kwambiri pamakina otsika kwambiri, otalikirapo (mpaka 100 metres) pazida zamagetsi zapanyumba, maukonde apanyumba, maukonde ogulitsa mafakitale, ndi makina amagalimoto. Ulusi wa perfluorinated polymer umagwiritsidwa ntchito nthawi zambiri pazida zothamanga kwambiri monga mawaya apakati pa data ndikumanga mawaya a LAN. Ma polymer optical fibers amatha kugwiritsidwa ntchito pozindikira kutali komanso kuchulukitsa chifukwa cha mtengo wake wotsika komanso kukana kwambiri.
Ubwino wa PMMA:
Palibe magetsi pamalo ounikira - zingwe za fiber optic zimanyamula kuwala kokha mpaka kuwunikira. Chowunikira ndi magetsi omwe amachipatsa mphamvu amatha kukhala mayadi ambiri kutali ndi zinthu kapena malo omwe akuyatsidwa. Kwa akasupe, maiwe, spas, shawa za nthunzi kapena saunas - fiber optic system ndiyo njira yabwino kwambiri yoperekera zowunikira.
Palibe kutentha pa malo ounikira - zingwe za fiber optic sizinyamula kutentha mpaka kuunikira. Sipadzakhalanso zowonetsera zotentha komanso sizidzawotchedwanso kuchokera ku nyali zotenthedwa ndi zida, ndipo ngati mukuyatsa zinthu zosagwirizana ndi kutentha monga chakudya, maluwa, zodzoladzola kapena zojambulajambula, mukhoza kukhala ndi kuwala kowala kopanda kutentha kapena kuwonongeka kwa kutentha.
Palibe kuwala kwa UV komwe kumawunikira - zingwe za fiber optic sizinyamula kuwala kwa UV mpaka kuwunikira, ndichifukwa chake malo osungiramo zinthu zakale otchuka padziko lonse lapansi nthawi zambiri amagwiritsa ntchito Fiber Optic Lighting kuteteza chuma chawo chakale.
Kukonza kosavuta komanso/kapena kwakutali - kaya vuto ndi mwayi wofikira kapena wosavuta, makina a fiber optic amatha kupangitsa kuyatsanso kamphepo. Pazinthu zomwe zimakhala zovuta kuzipeza, chounikiracho chikhoza kukhala pamalo osavuta kufikako, komanso kwa nyali zing'onozing'ono zingapo (zounikira zamasitepe, nyali zapaver kapena nyali) kusintha nyali imodzi yowunikiranso kuyatsanso kuwala kulikonse nthawi imodzi.
Pofuna kusunga zinthu zosalimba komanso zamtengo wapatali, makina opangidwa ndi fiber optic amapereka kuwala koma kofatsa.
