Raws li cov xwm txheej siv tau, cov kab hluav taws xob kho qhov muag feem ntau muab faib ua ntau pawg, suav nrog sab nraum zoov, sab hauv tsev, thiab sab hauv tsev / sab nraum zoov. Dab tsi yog qhov sib txawv ntawm cov pawg loj ntawm optical cables?
1. Sab nraum zoov Optical Fiber Cable
Hom kab hluav taws xob feem ntau peb ntsib hauv kev sib txuas lus engineering feem ntau yog sab nraum zoov optical fiber cable.
Txhawm rau ua kom tau raws li qhov xav tau ntawm kev siv sab nraum zoov, cov kab hluav taws xob sab nraum zoov feem ntau muaj kev ua haujlwm zoo thiab feem ntau siv cov qauv dej-pov thawj thiab dej-resistant.
Txhawm rau txhim kho qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob sab nraum zoov feem ntau suav nrog cov khoom siv hlau xws li cov hlau hauv nruab nrab lub zog thiab cov hlau armor txheej.
Cov yas-coated aluminium los yog yas-coated steel tapes nyob ib ncig ntawm cov tub ntxhais cable nthuav tawm cov khoom tiv thaiv zoo heev. Waterproofing ntawm lub cable yog tsuas yog tiav los ntawm kev ntxiv roj los yogdej thaiv cov xov pajraws li cov fillers hauv cov tub ntxhais cable.
Lub sheath ntawm sab nraum zoov optical fiber cables feem ntau yog ua los ntawm polyethylene. Polyethylene sheaths muaj lub cev zoo heev, kev tiv thaiv corrosion, lub neej ntev, kev ua haujlwm zoo, thiab lwm yam zoo, tab sis lawv tsis yog nplaim taws. Carbon dub thiab lwm yam additives feem ntau muaj nyob rau hauv lub sheath los txhim kho nws tsis kam mus rau ultraviolet hluav taws xob. Yog li ntawd, sab nraum zoov optical fiber cables uas peb pom feem ntau yog xim dub.
2.Indoor Optical Fiber Cable
Sab hauv tsev kho qhov muag fiber ntau cables feem ntau muaj cov qauv uas tsis yog xim hlau, nrog cov aramid fibers feem ntau siv los ua tus tswv cuab ntawm lub zog, pab txhawb kev hloov pauv.
Cov neeg kho tshuab kev ua tau zoo ntawm sab hauv tsev kho qhov muag fiber ntau cables feem ntau qis dua li ntawm sab nraum zoov cables.
Piv txwv li, thaum sib piv cov kab hluav taws xob sab hauv tsev tsim los rau txoj kab ntsug nrog kev ua haujlwm zoo dua rau cov kab hluav taws xob sab nraum zoov siv nyob rau hauv qhov chaw tsis muaj zog xws li cov kav dej thiab cov kab hluav taws xob uas tsis yog nws tus kheej, cov kab hluav taws xob sab hauv tsev tau zoo dua tensile quab yuam thiab tso cai rau lub zog flattening.
Sab hauv tsev kho qhov muag fiber ntau cables feem ntau tsis xav tau kev txiav txim siab rau cov dej noo-pov thawj, lossis UV tsis kam. Yog li ntawd, cov qauv ntawm cov kab hluav taws xob sab hauv tsev yog qhov yooj yim dua li cov kab hluav taws xob sab nraum zoov. Lub sheath ntawm sab hauv kho qhov muag fiber ntau cables tuaj nyob rau hauv ntau yam xim, feem ntau sib xws rau cov hom fiber optic cables, raws li qhia nyob rau hauv daim duab hauv qab no.
Piv rau cov kab hluav taws xob sab nraum zoov, cov kab hluav taws xob sab hauv tsev muaj qhov luv luv thiab feem ntau yuav tsum tau txiav tawm ntawm ob qho kawg.
Yog li ntawd, nyob rau hauv tsev cables feem ntau tshwm nyob rau hauv daim ntawv ntawm patch cords, qhov twg nyob rau hauv nruab nrab seem yog sab hauv tsev kho qhov muag fiber cable. Txhawm rau pab txhawb kev txiav tawm, cov cores fiber ntau ntawm cov kab hluav taws xob hauv tsev feem ntau muaj cov fibers nruj-buffered nrog txoj kab uas hla ntawm 900μm (thaum cov kab hluav taws xob sab nraum zoov feem ntau siv cov xim muaj xim nrog cov kab uas hla ntawm 250μm lossis 200μm).
Vim yog kev xa mus rau hauv ib puag ncig sab hauv tsev, sab hauv tsev kho qhov muag fiber ntau cables yuav tsum muaj qee yam hluav taws kub-retardant peev xwm. Nyob ntawm qhov ntsuas nplaim hluav taws xob, cov hlua hluav taws xob siv cov khoom siv hluav taws xob sib txawv, xws li nplaim taws-retardant polyethylene, polyvinyl chloride,Tsis tshua muaj pa luam yeeb xoom halogen nplaim-retardant polyolefin, lwm.
3. Sab hauv / Sab nraum zoov Optical Fiber Cable
Sab hauv / sab nraum zoov optical fiber cable, tseem hu ua universal sab hauv tsev / sab nraum zoov cable, yog ib hom ntawm cable tsim los siv rau sab nraum zoov thiab sab hauv tsev, ua ib tug conduit rau kho qhov muag teeb liab los ntawm sab nraum zoov mus rau sab hauv tsev ib puag ncig.
Sab hauv / sab nraum zoov fiber ntau optical cables yuav tsum tau sib txuas cov zoo ntawm sab nraum zoov cables xws li ya raws, dej tsis kam, zoo mechanical kev ua tau zoo, thiab UV tsis kam, nrog rau cov yam ntxwv ntawm sab hauv tsev cables, nrog rau cov nplaim taws retardancy thiab hluav taws xob tsis-conductivity. Hom kab no tseem hu ua ob lub hom phiaj hauv tsev / sab nraum zoov cable.
Kev txhim kho ua rau sab hauv / sab nraum zoov fiber ntau optical cables, raws li sab nraum zoov cables, suav nrog:
Kev siv cov nplaim-retardant cov ntaub ntawv rau lub sheath.
Qhov tsis muaj cov khoom siv hlau hauv cov qauv lossis kev siv cov khoom siv hlau nplaum uas yog cov khoom siv hluav taws xob tau yooj yim disconnected (xws li cov xaim xaim nyob rau hauv cov kev txhawb nqa tus kheej).
Kev siv cov kev ntsuas dej qhuav qhuav los tiv thaiv cov roj to thaum lub cable yog vertically deployed.
Hauv kev sib txuas lus zoo sib xws, cov kab hluav taws xob sab hauv tsev / sab nraum zoov tsis tshua siv tshwj tsis yog FTTH (Fiber to the Home) cov xaim xaim. Txawm li cas los xij, nyob rau hauv cov phiaj xwm dav dav uas cov kab hluav taws xob kho qhov muag feem ntau hloov ntawm sab nraum zoov mus rau sab hauv tsev, kev siv cov kab hluav taws xob sab hauv tsev / sab nraum zoov yog ntau zaus. Ob lub qauv ntawm cov kab hluav taws xob sab hauv tsev / sab nraum zoov siv hauv cov phiaj xwm cabling yog cov qauv xoob thiab cov qauv nruj-buffered.
4.Can Sab nraum zoov Optical Fiber Cables Yuav Siv Hauv Tsev?
Tsis yog, lawv ua tsis tau.
Txawm li cas los xij, nyob rau hauv cov qauv kev sib txuas lus engineering, vim feem ntau ntawm cov kab hluav taws xob kho qhov muag raug xa tawm sab nraum zoov, cov xwm txheej uas cov kab hluav taws xob sab nraum zoov tau ncaj qha mus rau sab hauv tsev yog qhov ntau heev.
Qee qhov xwm txheej, txawm tias qhov kev sib txuas tseem ceeb xws li cov xaim xaim rau cov ntaub ntawv tseem ceeb lossis kev sib txuas lus ntawm cov plag tsev sib txawv ntawm cov ntaub ntawv tseem ceeb siv cov kab hluav taws xob sab nraum zoov. Nws ua rau muaj kev phom sij tseem ceeb ntawm kev nyab xeeb rau lub tsev, vim tias cov kab hluav taws xob sab nraum zoov yuav tsis ua raws li cov qauv kev nyab xeeb hauv tsev.
5.Cov lus pom zoo rau kev xaiv Optical Fiber Cables hauv tsev Infrastructure
Daim Ntawv Thov Yuav Tsum Siv Hauv Tsev thiab Sab Nraud: Rau cov ntawv thov cable xav tau kev xa tawm sab nraud thiab sab hauv tsev, xws li cov xaim xaim thiab cov xaim xaim mus rau hauv lub tsev, nws raug nquahu kom xaiv rau sab hauv tsev / sab nraum zoov fiber ntau optical cables.
