Optical fiber ntauisa lub teeb conduction cuab tam uas siv lub hauv paus ntsiab lus ntawm tag nrho cov kev xav ntawm lub teeb nyob rau hauv ib tug fiber ntau ua los ntawm iav los yog yas.
Optical fiber liab qab fiber ntau feem ntau muab faib ua peb txheej: core, cladding thiab txheej.
Optical fiber core thiab cladding yog tsim los ntawm iav ntawm txawv refractive indices, nrog ib tug siab refractive index iav core (germanium-doped silicon dioxide) nyob rau hauv nruab nrab thiab ib tug tsawg refractive index silicon iav cladding (ntshiab silicon dioxide) nyob rau hauv nruab nrab. Lub teeb raug tua rau hauv cov fiber ntau ntawm ib qho xwm txheej ntawm lub kaum ntse ntse, thiab tag nrho cov emission tshwm sim ntawm fiber ntau thiab cladding (vim qhov refractive Performance index ntawm cladding yog me ntsis qis dua cov tub ntxhais), thiaj li hais tias nws muaj peev xwm propagate los ntawm fiber. Lub luag haujlwm tseem ceeb ntawm txheej txheej yog los tiv thaiv cov fiber ntau los ntawm kev puas tsuaj rau sab nraud, thiab tib lub sijhawm ua kom muaj kev hloov pauv ntawm cov fiber ntau. Raws li tau hais ua ntej, cov tub ntxhais thiab cladding yog ua los ntawm iav, uas tsis tuaj yeem khoov thiab tsis yooj yim, thiab kev siv cov txheej txheej tiv thaiv thiab ncua lub neej ntawm cov fiber ntau.
Cov saum toj no yog "fiber structure" coj los ntawm HDV Phohluav taws xobTechnology LTD.Peb lub tuam txhab yog cov khoom siv kho qhov muag tshwj xeeb uas yog cov tuam txhab tsim khoom loj, cov khoom siv sib txuas sib txuas npog OLT series, ONU series, hloov series, optical module series thiab lwm yam, txais tos kom nkag siab.
