Polymer Optical Fiber (POF) ndi Optical Fiber yopangidwa ndi zinthu zapamwamba za refractive index polymer monga fiber core ndi low refractive index polymer material monga zomangira.Mofanana ndi quartz optical fiber, pulasitiki ya kuwala imagwiritsanso ntchito mfundo yowonetsera kuwala.Optical fiber core ndi yopepuka yowirira kwambiri ndipo chotchingiracho ndi chopepuka chowundana.Mwanjira imeneyi, malinga ngati mbali ya kuwala kolowera ili yoyenera, kuwala kwa kuwala kudzawonekera mosalekeza mkati mwa kuwala kwa kuwala ndikufalikira kumapeto kwina.
Ubwino wa pulasitiki kuwala CHIKWANGWANI
Kuyankhulana kwa ma fiber opangidwa ndi kuwala kuli ndi maubwino atatu kuposa kulumikizana kwachikhalidwe kwamagetsi (mkuwa): choyamba, kulumikizana kwakukulu;Chachiwiri, ili ndi kusokoneza kwabwino kwa anti electromagnetic komanso chinsinsi;Chachitatu, ndi wopepuka kulemera kwake ndipo ungapulumutse mkuwa wambiri.Mwachitsanzo, kuyala chingwe cha 1000 km kutalika kwa 8-core Optical cable kungapulumutse matani 1100 amkuwa ndi matani 3700 amtovu kuposa kuyala chingwe cha 8-core chautali womwewo.Choncho, pamene chingwe cha kuwala ndi kuwala chinatuluka, chinalandiridwa ndi makampani olankhulana, omwe anabweretsa kusintha kwa njira yolankhulirana ndi kuzungulira kwa ndalama ndi chitukuko.Ngakhale kuwala kwa quartz (galasi) kuli ndi zabwino zomwe tatchulazi, kumakhala ndi kufooka koopsa: kutsika kwamphamvu, kusasunthika kosasunthika komanso kusakanizidwa bwino ndi ma radiation.
Poyerekeza ndi quartz kuwala CHIKWANGWANI, pulasitiki kuwala CHIKWANGWANI ndi chimodzi mwa zipangizo kwa makampani zidziwitso ndi kafukufuku wanthanthi ndi chiyembekezo ntchito m'munda wa Polymer Science m'zaka 20 posachedwapa.Lili ndi izi:
(1) M'mimba mwake ndi yayikulu, nthawi zambiri mpaka 0.5 ~ 1mm.Chingwe chachikulu cha CHIKWANGWANI chimapangitsa kulumikizana kwake kukhala kosavuta komanso kosavuta kugwirizanitsa, kotero kuti zolumikizira zopangira jekeseni zotsika mtengo zitha kugwiritsidwa ntchito ndipo mtengo woyika ndi wotsika kwambiri;
(2) Kubowola kwa manambala (NA) ndi kwakukulu, pafupifupi 0.3 ~ 0.5, ndipo kugwirizanitsa bwino ndi gwero la kuwala ndi chipangizo cholandira ndipamwamba;
( 3) Chitsanzo chothandizira chimakhala ndi ubwino wa zipangizo zotsika mtengo, zotsika mtengo zopangira komanso kugwiritsa ntchito kwakukulu.
