Dab tsi yog Kab rov tav (Inline) Splice Kaw?
Kab rov tav (inline) splice kaw muaj qhov ntev, raj -zoo li los yog tiaj tus cylindrical zoo nrog cable nkag chaw nres nkoj ntawm ob qho kawg. Cables nkag los ntawm ib sab, yog spliced nyob rau hauv, thiab tawm mus rau sab nraud - ua raws tib txoj kab ncaj nraim li lub cable nws tus kheej.
Tej kev siv:
• Cov kav dej thiab cov kav dej txuas qhov twg cov cables khiav los ntawm cov kav dej ua ntej
• Direct burial nyob rau hauv nqaim trench
• Ncaj-los ntawm kev sib txuas ntawm ob txoj kab sib npaug
• Kho cov kab uas puas lawm
Rau ntev -haul backbone networks uas cov cable tsuas txuas ntxiv yam tsis muaj ceg, kaw hauv kab feem ntau yog qhov chaw - xaiv tau zoo.
Dome Splice Kaw yog dab tsi?
Lub dome splice kaw muaj ib lub cylindrical, dome -puab lub cev nrog rau tag nrho cov cable nkag los hauv qab. Cov fibers nkag los ntawm ib qho kawg kaw, yog spliced thiab khaws cia rau hauv lub dome, thiab ces tawm rov qab los ntawm tib kawg -feem ntau mus rau ntau ceg cables.
Tej kev siv:
• Aerial ncej- mounted installations (cov kab hluav taws xob nkag hauv qab, dai ntsug)
• Manholes thiab handholes (chaw-qhov chaw ntsug zoo)
• Phab ntsa-mounting hauv MDU txoj kev hauv tsev
• Nruab nrab - ncua kev nkag mus rau qhov twg cables raug tapping yam tsis raug txiav
Vim li cas lub dome puab?Qhov nkhaus saum toj ib txwm tso dej, dej khov, thiab khib nyiab. Nws sib npaug sib faib sab nraud los ntawm kev faus lossis dej rau hauv av, thiab ib qho - qhov kawg foob yog qhov muaj kev ntseeg siab dua li kev khi ob qhov kawg.
Qhov tseem ceeb sib txawv 1: Cable nkag Configuration thiab Routing
Kab rov tav (Inline): Ob txoj kev nkag
Nrog cov cables nkag los ntawm ob qho kawg, kab rov tav kaw tau ua kom zoo rau kev ncaj nraim - los ntawm kev khiav cable. Qhov no ua rau lawv zoo tagnrho rau cov kab ntev - deb ntawm lub cev qhov chaw uas lub cable cia li mus. Txawm li cas los xij, vim tias cov cables los ntawm cov lus qhia tsis sib xws, kev sib txuas hauv fiber ntau yuav tsum tau ua tib zoo npaj-tshwj xeeb tshaj yog nyob rau hauv qhov chaw kaw.
Dome: Ib-Txoj kev nkag
Nyob rau hauv dome kaw, tag nrho cov cables los ntawm ib qho kev taw qhia. Qhov no ua kom yooj yim rau kev teeb tsa rau saum huab cua ncej mounts (cables nkag los ntawm hauv qab, faib upward) thiab ua rau ceg splicing ntau intuitive. Thaum koj xav tau coj ib lub feeder cable thiab faib nws mus rau hauv ob peb lub xaim xaim mus rau cov lus qhia sib txawv, lub dome tsim qhov sib koom ua ke nkag nkag yog qhov haum.
Qhov zoo ntawm Fiber Management Advantage
Lub koom haum Fiber Optic sau tseg tias cov dome kaw yog "yooj yim dua los tuav thaum sib txuas thiab khaws cov kev pabcuam kev pabcuam," thiab qhov kev sib piv pom tau zoo: cov dome kaw kom fibers zoo dua qub, tshwj xeeb tshaj yog thaum rov qab kaw rau kev txav, ntxiv, thiab hloov.
Qhov txawv ntawm qhov tseem ceeb 2: Kev thov kom haum
Kab rov tav kaw zoo tshaj hauv:
• Underground ducts:Lawv cov duab elongated fits zoo nyob rau hauv nqaim conduits.
• Direct burial trench:Qhov qis -profile tsim tuaj yeem faus tsis tas yuav muaj kev khawb loj.
• Kev kho lub cev:Thaum ib lub cable raug txiav, ib qho kaw inline splices nws rov qab ua ke yam tsis hloov lub cable lub cev hneev taw.
• Ncaj-ceg taw tes-rau-point:Ib qho kev tsim inline yog ib txwm xaiv thawj zaug thaum cables nkag thiab tawm ntawm sab nraud.
Dome kaw zoo tshaj hauv:
• Aerial ncej-mounting:Dai qhov kaw los ntawm ib tug ncej nrog cables nkag los hauv qab no -natural thiab gravity- pab.
• FTTH faib cov ntsiab lus:Faib ib lub feeder cable rau hauv ntau lub xaim xaim mus rau ib tus neeg lub tsev lossis kev lag luam.
• Manhole thiab handhole installation:Compact footprint haum yooj yim rau hauv qhov chaw kaw.
• Nruab nrab-span nkag:Tapping ib lub cable tsis txiav nws yooj yim dua nrog lub dome kaw.
Qhov txawv tseem ceeb 3: Fiber Peev Xwm thiab Kev Tswj Xyuas
Kab rov tav kaw: Linear ntom
Vim lawv cov duab ntev, nqaim, kab rov tav kaw yuav tsum ua tib zoo xa cov fibers raws qhov ntev ntawm qhov kaw. Qhov no tuaj yeem dhau los ua qhov nyuaj rau kev sib txuas siab. GL09-6809-C ua haujlwm txog li 144 fibers, tab sis vim tias tag nrho cov tais fiber ntau tau muab tso rau hauv ib qho kev npaj, cov kws tshaj lij yuav tsum tswj xyuas kom zoo kom tsis txhob muaj qhov tsawg kawg nkaus khoov vojvoog.
Dome Closures: Concentric ntom ntom
Nrog lawv cov voj voog, domed zoo, dome kaw npaj cov tais ntim rau hauv ib qho kev sib tw, concentric qauv. Qhov no ua rau fiber ntau routing intuitive thiab feem ntau muab kev nkag tau zoo dua rau ib tus neeg lub tais yam tsis muaj kev cuam tshuam lwm tus. GL-5601, piv txwv li, siv txog li 6 lub tais, txhua lub tais tuav 24 ib leeg fibers (los yog 72 ribbon fibers), rau tag nrho ntawm 144 ib fibers (los yog 432 ribbon fibers). Qhov kaw kuj haum rau 1 PLC splitter thiab 6 qhov chaw nres nkoj (1 oval ntxiv rau 4 puag ncig) rau kev tswj cov kab hluav taws xob hloov tau yooj yim, muab qhov tseeb ntau txoj haujlwm splice node nyob rau hauv ib qho kev cog lus cylindrical hneev taw.
Qhov txawv tseem ceeb 4: Kev sib khi thiab rov nkag
Mechanical Seals (nrog rau ob hom)
Mechanical seals siv gaskets, O-rings, los yog clamp mechanisms uas yog compressed los ntawm screws los yog latches, ua kom rov qhib dua yam tsis tau hloov cov khoom sealing.
GL09-6809-C siv lub tshuab sealing tshuab xa IP68 tiv thaiv, thiab nws cov ntsia hlau, gaskets, thiab fasteners yog ua los ntawm 304 stainless hlau rau corrosion kuj. Ntau cov kab rov tav kaw kuj tseem siv cov tshuab ntsaws ruaj ruaj, tso cai rau kev rov nkag tau yooj yim rau kev kho thiab hloov kho dua tshiab.
Kub-Shrink Seals (ntau dua ntawm dome kaw)
Qee lub dome kaw, tshwj xeeb tshaj yog cov uas tsim los rau kev tiv thaiv siab heev, siv cov cua sov-shrink seals- tsim kom muaj kev ruaj ntseg, 360℃thaiv thaiv. Kev lag luam tawm -tawm yog qhov cua sov-shrink kaw kaw tsis tuaj yeem rov qhib dua yam tsis tau txiav lub tes tsho thiab siv ib qho tshiab.
Ib leeg-Xaus vs. Dual-Xaus Sealing
Dome kaw tsuas muaj ib qho kev sib txuas (hauv qab nkag). Kab rov tav kaw muaj ob (ob qhov kawg). Tsawg sealing interfaces txhais tau tias tsawg dua cov ntsiab lus tsis ua haujlwm. Qhov kev tsim qauv tseem ceeb no piav qhia vim li cas FOA piav qhia txog lub dome "ib qho kawg foob tuaj yeem ntseeg tau ntau dua".
Xaiv Txoj Cai Kaw: Ib Qhov Kev Txiav Txim Siab Ua Haujlwm
Siv kab rov tav (inline) kaw thaum:
1.Koj tab tom splicing ob cables nyob rau hauv ib tug ncaj-los ntawm configuration (piv txwv li, ncua ib lub cev kab).
2.Qhov kaw yuav raug ntsia rau hauv qhov nqaim, cov kav dej, lossis qhov chaw faus ncaj qha.
3.Space yog constrained nyob rau hauv lub longitudinal kev taw qhia (xws li, nyob rau hauv ib tug manhole qhov ntev tseem ceeb tshaj qhov siab).
4.Qhov tsawg kawg nkaus yuav tsum tau txiav; Koj feem ntau xav tau inline splicing.
5.Koj xav tau ib qho re- nkag tau lub tshuab foob rau kev kho thiab hloov kho yav tom ntej.
6.Koj qhov tseem ceeb yog ua kom haum rau kev kaw rau hauv ib qho kev nthuav dav uas twb muaj lawm.
Siv lub dome kaw thaum:
1.Koj tab tom txiav ib lub tshuab pub rau hauv ntau lub xaim xaim (xws li FTTH hub splitting rau 8-16 tus neeg siv khoom).
2.Qhov kaw yuav raug ntsia rau hauv qhov chaw huab cua (ncej-mounted, strand-hung) lossis manhole nrog qhov chaw kab rov tav.
3.Nruab nrab- ncua kev nkag yuav tsum tau-tapping lub cable yam tsis tau txiav.
4.Qhov kaw yuav qhib thiab kaw ntau zaus hauv nws lub neej (xws li, ntxiv, txav, hloov).
5.Koj yuav tsum tau ua ke cov khoom siv passive xws li PLC splitters nrog rau kev sib txuas.
6.Koj lub network node xav tau "splice + termination" multi- muaj peev xwm ua haujlwm.

Xaus: Xaiv los ntawm Geometry thiab Daim Ntawv Thov, Tsis yog los ntawm Habit
Thaum txiav txim siab ntawm kab rov tav thiab dome splice kaw, cia lub geometry ntawm lub installation thiab topology ntawm lub network coj koj xaiv, tsis yog tus cwj pwm los yog khoom muaj.
• Kab rov tav (inline) kawyog kho kom haum rau ncaj-kab, ob- xaus cable nkag- zoo tagnrho rau cov kav dej, faus ncaj qha, thiab kho lub cev. Lawv ua tau zoo nyob rau hauv constrained linear qhov chaw.
• Dome kawtau kho kom zoo rau ib qho - tas lawm, ntau - ceg cable nkag - zoo tagnrho rau cov ncej saum toj kawg nkaus, FTTH faib cov ntsiab lus, thiab nruab nrab - ncua kev nkag. Lawv zoo nyob rau hauv complex branching topologies.
