Nyob rau xyoo tas los no, nrog rau kev txhim kho ntawm kev lag luam cov ntaub ntawv kho qhov muag thiab kev txhawb nqa cuam tshuam, FTTH (Fiber rau Tsev) tau dhau los ua tus qauv kev daws teeb meem rau kev txhim kho tsis ntev los no ntawm kev nkag mus rau hauv tes hauj lwm. Nws hloov kho rau kev nce qib hauv kev siv tshuab hauv thaj chaw kho qhov muag thiab sib haum nrog cov kev xav tau ntawm kev xa xov xwm ceev ceev, muaj peev xwm siab ntawm cov neeg siv hauv tes hauj lwm kho qhov muag. Hauv cov haujlwm nkag mus rau FTTH muaj peev xwm siab, lub zog khoov thiab lub zog tensile ntawm cov xov hluav taws xob sab hauv tsev tsis tuaj yeem ua tau raws li qhov xav tau ntawm FTTH sab hauv tsev cabling. Hauv kev teb rau kev thov ua lag luam, cov xov hluav taws xob fiber ntau lub zog siab, qis-bend-radius tawv-clad tau tshwm sim thiab siv dav hauv FTTH nkag mus rau tes hauj lwm.
Qhov kev ncua deb tshaj plaws ntawm cov xov hlau poob tuaj yeem ncav cuag 70 kilometers. Txawm li cas los xij, feem ntau, theem kev tsim kho npog lub network fiber optic backbone mus txog rau lub tsev thiab tom qab ntawd decoded nws los ntawm lub optical transceiver. Txawm li cas los xij, yog tias ib qhov project ib mais yog ua tiav siv cov xov hlau tawv-clad, nws yuav tsum yog kev teeb tsa sab nraud. Cov xov hlau tawv-clad nws tus kheej yog qhov tsis muaj zog heev, ua rau nws yooj yim heev rau kev tawg, thiab nws cov durability tsis siab heev.
Vim nws qhov mos mos thiab sib dua, cov cable poob no siv dav hauv cov tes hauj lwm nkag. Lub npe scientific rau cov cable poob yog cov kab nkag zoo li npauj npaim rau cov tes hauj lwm nkag; nws tseem hu ua kab npauj npaim vim nws cov duab. Nws yog siv los ua cov cables optical thiab cov cables optical duab yim.
Cov xov hlau uas muaj txheej: Nws yog cov fiber ntau uas tsis yooj yim khoov uas tuaj yeem muab cov bandwidth siab dua los txhim kho kev ua haujlwm ntawm kev sib kis hauv network; nrog ob lub FRP sib luag lossis cov hlau txhawb nqa, cov xov hlau kho qhov muag muaj kev tiv thaiv zoo los tiv thaiv cov fiber ntau; cov xov hlau kho qhov muag muaj cov qauv yooj yim thiab lub teeb yuag, thiab kev siv tau zoo; nws muaj qhov tsim tshwj xeeb, yooj yim tev tawm, tuaj yeem yooj yim rau kev sib txuas.
Yog tias nws yog ib hom, nws tuaj yeem mus deb dua, tab sis yog tias qhov project ib-kilometer ua tiav nrog cov hlua tawv, nws yuav tsum yog qhov project sab nraud, yog li nws zoo li cov hlua tawv tsis yooj yim tawg, yooj yim tawg, thiab tsis muaj zog rau kev khiav ntev.
