Cov nyo hau-hom poob cable, feem ntau yog hu ua tus npauj npaim kho tshiab lossis sab hauv qab zib cable, derives nws lub npe los ntawm nws tus npauj npaim-puab cross-zoo nkauj. Cov cable no yog qhov siv tau ntau yam hauv lub tsev (FTH) cov phiaj xwm, muab ib cov qauv kev cog lus, kev teeb tsa yooj yim, thiab kev ua tau yooj yim.
1. Cov qauv ntawm cov nyo hau-hom nco cable
Tsim los ua kom tau raws li cov ntaub ntawv hluav taws xob hauv tsev sab hauv tsev, cov hneev-hom poob Cable suav:
• Chav tsev fiber ntau: nyob rau centraly, chav tsev feem ntau siv ib hom-hom lossis ntau hom fibers los kis cov paib kho qhov muag.
• Cov Tswvcuab Lub Zos: Ua kom cov khoom siv sib txuas ua ke ntawm ob tog, ua los ntawm cov ntaub ntawv tsis muaj fiber ntau ntxiv xws li cov xov hlau, muab cov xaim hluav taws xob thiab kev pabcuam tshuab hluav taws xob.
• Sheath: Cov nqaij ntshiv sab nraud, ua los ntawm cov pa luam yeeb tsawg, cov khoom siv nplaim taws, ua kom muaj kev nyab xeeb thiab ib puag ncig kev tiv thaiv thiab ib puag ncig thaum lub sijhawm siv sab hauv tsev.
• Cov teeb meem ya raws: qee cov hneev-cov cable muaj cov cable sab hauv kom tiv thaiv dej vapor intrusion, kev tiv thaiv fiber ntau.
Cov qauv tsim qauv no xaus rau cable nrog yooj thiab hloov me nyuam me, ua rau nws haum rau kev xa tawm chaw.
2. Cov yam ntxwv tseem ceeb ntawm cov hneev-hom nco cable
• Kev cog lus kev cog lus: nrog lub tiaj tiaj tus thiab qhov me me (piv txwv li, 2 {} mm} Kuv yog qhov zoo tagnrho rau cov xaim sab hauv tsev, tshwj xeeb tshaj yog hauv qhov chaw tsawg.
• Muaj peev txheej siab: tus qauv tsim tshwj xeeb los ntawm khoov thiab khawm thaum lub teeb tsa, yoog raws ib puag ncig thiab txoj kev txo cov nqi thiab cov nuj nqis.
• Cov tswv yim zoo heev thiab compression kuj: lub zog ntawm cov tswv yim muab lub zog tseem ceeb thiab sab nrauv lub sijhawm ua kom muaj txiaj ntsig thaum lub sijhawm kev teeb tsa thiab siv.
• Yooj yim ntawm kev teeb tsa thiab kev saib xyuas: v-puab grooves ntawm ob sab pab yooj yim stripping thiab splicing kev tsim kho thiab tus nqi.
• High bandwidth thiab nrawm: muaj peev xwm ua tau raws li ntau cov fibers, sib dhos cov kev xav tau rau kev kub ceev, loj sib txuas lus thiab kev sib tham.
3. Kev thov cov xwm txheej ntawm hneev-hom nco cable
Lub hau-hom nco cable nrhiav pom dav dav hauv kev sib txuas lus hauv niaj hnub no thiab kev sib koom tes, suav nrog:
• Fiber rau hauv lub tsev (FTH): siv rau sab hauv tsev cov thawv ntawv los ntawm cov thawv hloov kho kho qhov muag
• Cov chaw tawm tswv yim: Kev txhawb nqa cov ntaub ntawv ceev ntawm cov servers lossis ntawm servers thiab cov khoom siv cia, ua kom muaj kev sib tw siab.
• Lub chaw ua haujlwm xaim hluav taws xob: dav tau txais hauv kab rov tav thiab ntsug nyob rau hauv cov tsev ua haujlwm vim nws qhov yooj thiab yooj yim ntawm kev teeb tsa.
• Kev siv tshuab ua: Ua haujlwm rau kev sib txuas ntawm cov khoom siv ntawm cov chaw muaj kev lag luam, ua kom cov ntaub ntawv sib luag, cov ntaub ntawv ceev ceev.
4. Xaiv cov lus pom zoo rau cov hneev-hom nco cable
Thaum xaiv ib rab hneev-hom poob Cable, xav txog cov hauv qab no:
• Kev khiav haujlwm ua haujlwm: rau kev siv nyob sab hauv tsev, xaiv cables nrog cov tswv yim tsis yog xim hlau los tiv thaiv cov xob laim thiab cuam tshuam hluav taws xob; Rau kev siv sab nraum zoov, txhawb nqa hneev-hom dee cables nrog hlau ntawm cov tswv cuab tsim nyog, tab sis nws yog xim hlau yuav tsum tau muab tshem tawm thaum cov nkag sab hauv.
• Hom Fiber: Txhawm rau kom txo qis ntxiv vim nws yuav tsum xaiv cov radii me me, nws tau tshawb xyuas kom xaiv cov roj tsis raws cai nrog G.657.A2 tus qauv.
• Cov ntaub ntawv siv pob: rau cov ntawv thov sab hauv tsev, rub tawm cov pa luam yeeb tsawg, halogen-retardant cov ntaub ntawv kom tau raws li ib puag ncig thiab hluav taws kev nyab xeeb.
5. Kev loj hlob ntawm cov hneev-hom nco cable
Nrog rau kev nce qib tsis tu ncua hauv kev sib txuas lus thev naus laus zis, nyo hau-hom poob cables yog hloov zuj zus mus ntsib daim ntawv thov tshiab:
• Cov qauv tsim muaj ntau hom kev tsim qauv: kom haum kom haum rau ntau dua bandwidth xav tau, cov qauv tsim muaj ntau cov fibers nyob rau hauv tib qhov ntev yog tshwm sim.
• Txhim kho cov ntaub ntawv zoo li cov ntaub ntawv: kev saws cov khoom tshiab txhim kho lub cable huab cua tiv thaiv thiab cov khoom siv tshuab, ua rau nws tiv thaiv cov chaw ntau dua.
• Kev saib xyuas kev ua kom muaj zog: fiber ntau inglicecting tshuaj thev naus laus zis nyob rau hauv cable tso cai saib xyuas lub sijhawm tiag tiag thiab kev ntxhov siab, txhim kho network txij nkawm zoo.
6. Xaus
Cov hneev-kab kos Cable, nrog nws cov qauv kev tsim qauv thiab kev ua tau zoo dua, tau dhau los ua kev sib txuas lus tsis tseem ceeb ntawm kev sib txuas lus niaj hnub no. Los ntawm cov qauv rau kev thov, nws ua kom pom zoo hauv cov ntaub ntawv muaj kev sib kis nrawm, yooj yim ntawm kev teeb tsa, thiab txij nkawm. Raws li thev naus laus zis tseem ua ntej, cov hneev-zwm-poised kom ua lub luag haujlwm tseem ceeb hauv ntau daim teb thiab kev txhim kho kev sib txuas lus.
