Loose-Tube VS. Ceev-Buffered Fiber Optic Cable
Nws paub tias fiber optic cable tau qhov nruab nrab ntawm cov chaw nruab nrab ntawm cov ntaub ntawv chaw qaum vim cov muaj peev xwm thiab cov nplai, tag nrho kev tiv thaiv mus rau electromagnetic cuam tshuam (EMI) thiab xov tooj cua zaus cuam tshuam (RFI), tshem tawm ntawm qhov kev nkag siab ntawm lub hauv siab twinax cable), lub me me, thiab yooj yim ntawm installation, tshwj xeeb tshaj yog thaum siv pre-raug kaw modular pob tw cables. Xaiv lub hom phaj ntawm fiber ntau ntawm fiber optics boils down to the applications and installation. Cov ncej no yuav ua kom paub thiab piv tau ob hom fiber optic cable raws li ntau txoj hlua kab-xoob-raj thiab nrawm-buffered fiber optic cable.
Kev siv rau hauv qhov siv xoob raj, cov fibers tau muab tso rau hauv cov hlua uas rub tawm, uas yog siv cov hlua kom ncav tsis ncab cov fiber ntau xwb, uas tuaj yeem tiv thaiv tau qhov teeb meem ntawm qhov nro thaum tso thiab vim kub hloov. Loose-tube fibers tej zaum yuav yog "qhuav thaiv" lossis gel-ntim. Qhuav thaiv muaj tsawg tiv thaiv rau cov fiber ntau dua gel, tab sis cov nqi tsis tshua muaj nqis. Loose-tube fibre cable los ntawm ntau hom kev suav hais tias feem ntau yog li ntawm 6 txog 144, nrog qee lub tuam txhab muab ntau dua suav mus txog 216 fibers. Tsuas yog 6-fiber ntau, cov fibers yog pawg ua pawg hauv 12 ntawm qhov siab tshaj plaws.

Cov tsho sab nrauv (PVC yog cov khoom siv rau sab nraum zoov vim nws txoj kev ua tsis taus pa, ua kom tsis muaj zog thiab ruaj khov ntau yam kub tshaj plaws).
Tsis tshua muaj Kev Kub Kub: Cov kab xov dhos xoob hluav taws xob tsim kom muaj qhov chaw tsis muaj dab tsi rau cov khoom siv fiber ntau los ntawm kev siv lub zog ntawm cov teebmeem sab nraud, uas ua rau huab cua sov zoo. Dhau li ntawd, qhov yeeb yam no kuj ua rau kev ua tiav ntawm txoj kab xoob xauv hlau tsim hauv ntau yam ntawm cov khoom siv dag zog, xws li kev sib tw, kev sib zog, kev sib tw, tsoo, thiab lwm yam.
Kev Tiv Thaiv Dej Ntaus: Raws li peb txhua tus paub, tub ntxhais fiber ntau ntawm cov kab xoob xaim hluav taws xob ncig nrog cov ntaub nplaum nplaum nplaum thiab cov iav, los yog cov gel, uas tuaj yeem ua kom tsis txhob nkag thiab tsiv ntawm dej.
Kev Tiv Thaiv UV: Cov tsho khoob ntawm cov hlua khoob rau cov kab uas muaj cov kab xo, uas muaj peev xwm muab kev tiv thaiv ultraviolet siab tshaj plaws, ua kom muaj peev xwm tiv thaiv tau cov kab mob sab nraud ntawm lub tshav ntuj sab hauv lub dav hlau.
Siv lub raj xauv, lub fiber ntau yuav nkag tau rau hauv lub hnyav hnyav polymer, feem ntau hu ua "tsis nruj" siv. Taub-buffered cables muaj rau ntau yam kev siv, tab sis ob feem ntau yog "tawg" thiab "faib". Tight-buffered cable los hauv fiber ntau suav xws li 2 mus rau 144 fibers, nrog cov fiber ntau cov zauv uas muaj fiber ntau subunits ntawm 6 los sis 12 fibers hauv kab. Piv txwv, tus kab mob 144-fiber ntau tau kaum ob 12-foob subunits thaum lub xov tooj 36-fiber ntau muaj rau 6-fiber ntau los sis peb 12-foob subunits.
Cov duab hauv qab no qhia tau hais tias cov qauv ntawm cov hlua khawm nrawm.
Ntau yam 900um nruj-buffered fibers stranded nyob ib ncig ntawm lub zog ntawm tus tswv zog.
Central zog tus tswv cuab hauv nruab nrab ntawm qhov cable.
Aramid Yarn (Kev hloov lub npe Kevlar) qhwv ib ncig ntawm lub fibers rau kev tiv thaiv lub cev thiab txoj hlua cable.

Cov tsho lub tsho los yog lub tais (feem ntau PVC).
Yooj Yim Rau Nruab Nrab: Cov kab no muaj qhov yoojyim rau nruab, vim tias tsis muaj kev tuaj yeem tuaj yeem tu thiab lawv tsis xav tau cov khoom siv kiv cua tawm rau kev sib txuas lossis kev txiav. Koj tuaj yeem crimp txuas ncaj nraim rau txhua tus fiber ntau.
Kev Cuam Tsheej Yooj Yim Ntau Tshaj: Raws li kev siv tub rog kev lag luam rau kev ciaj sia nyob rau hauv kev kho vaj tse thiab ib puag ncig.
Yooj Yim: Tsis muaj rab qaum zog, yuav tsum ua kom yooj yim dua. Lub cable kuj yog "nruj txhua yam" uas nws yuav tsum tau rub tawm ntau txoj hlua khiab lossis dai vertically tsis ua rau "lub ntsej muag fais fab".
Tom qab peb tau qhia txog ob hom kev siv fiber ntau, cov neeg xav paub seb qhov twg yog qhov zoo tshaj plaws rau lawv qhov project. Ua tau, cov kab no ob hom yog muab tso rau hauv cov ntawv sib txawv.
Loose-tube cable yog tsim los rau tej qhov chaw hnyav. Nws muaj cov dej-resistant gel uas ncig lub fibers, uas pab cov fibers los ntawm noo noo, ua zoo tagnrho rau hnyav, siab-qhov av ntau qhov twg dej los yog qhov hnyuv yaus yuav muaj teeb meem. Cov hlab dej tuaj yeem tuaj yeem nthuav thiab cog lus nrog kev hloov kub. Loose-cable cable muaj lub siab dua tensile zog tshaj kab nrib-buffered. Tab sis nws tsis yog qhov zoo tshaj plaws xaiv thaum cable xav tau kev los ntawm ntau ntau khoov, uas feem ntau muaj tseeb nyob rau hauv cov ntaub ntawv sab hauv. Cuab pwm ntau dhau los muaj peev xwm ua kom muaj fibers tawm hauv npav.
Tight-buffered cable optimized rau cov ntaub ntawv nyob sab hauv tsev. Vim hais tias nws yog sturdier tshaj li xoob raj, nws muaj ntau rau kev sib sim ntev LAN / WAN kev sib txuas los yog ntev hauv tsev khiav, thiab txawm ncaj faus. Tight-buffered cable kuj pom zoo rau kev siv dej hauv qab.
Xaiv hom kab xov xwm zoo rau koj daim ntawv sau tau zoo tuaj yeem txhim kho kev ua haujlwm hauv network thiab xyuas kom meej txog lub neej ntawm kev ua haujlwm tag nrho. Xav ob zaug ua ntej xaiv fiber ntau optic cable.
