Kev sib tw Branching hauv High-Density ODN Networks
Hauv Open Distribution Network (ODN), lub caj qaum kho qhov muag cables los ntawm lub hauv paus chaw ua haujlwm feem ntau siv 144, 288, lossis ntau dua cores. Cov high -core- suav cables yog nteg nyob rau hauv lub nroog arterial txoj kev los yog nyob deb nroog txoj kev, ceg tawm mus txuas mus rau tej thaj chaw, cov tsev lag luam, los yog lub hauv paus chaw nres tsheb ntawm ob sab.
Ib txwm me me -muaj peev xwm fiber ntau optic fusion splices ntsib kev sib tw thaum tuav 288-core trunk optical cables: tag nrho 288 fibers raug txiav thiab spliced ib tug los ntawm ib tug - uas tsis yog tsuas yog kev ua hauj lwm -intensive tab sis kuj qhia txog tej zaum cov ntsiab lus ntawm tsis ua hauj lwm nrog txhua 7} splice uas xav tau cov ceg { tsis siv fibers coiled hauv lub thawv splice. Txawm li cas los xij, me me-muaj peev xwm fusion splices feem ntau tsis muaj qhov chaw seem txaus kom haum rau ntau tshaj 200 cov fibers tsis txaus.
Hauv -Line Design: Txoj Kev Txawj Ntse ntawm Kev Tawm Hauv Lub Cev Cable Uncut
Tus nqi tseem ceeb ntawm 288-core fiber optic splice lub thawv nyob hauv nws "tsis muaj-txiav voj-los ntawm" tsim lub tswv yim. "Loop-through" txhais tau hais tias lub cev kho qhov muag cable tuaj yeem dhau los ntawm lub thawv splice yam tsis tau txiav; tsuas yog cov fibers kho qhov muag uas yuav tsum tau branched yog spliced nyob rau hauv, thaum lub sij hawm ntxiv optical fibers nyob twj ywm.
Hauv kev xyaum, qhov haujlwm no feem ntau hu ua "qhov rais stripping." Lub installer tsuas yog tshem tawm cov txheej txheem ntawm lub cev ntawm lub cev ntawm qhov chaw kaw, txheeb xyuas cov hlab tsis xav tau cov ceg, txiav thiab sib txuas cov fibers tshwj xeeb, thiab tawm ntawm cov hlab tsis siv tsis zoo, ncaj qha coiled hauv qhov chaw kaw qhov chaw cia.
Tus nqi engineering ntawm qhov kev tsim no yog pom tseeb thoob plaws ntau qhov ntev:
Khaws lub cev ruaj khov- Tsis txiav cov pob txha caj qaum txhais tau hais tias tsis muaj fusion splices ntxiv, yog li txo qis kev sib kis thiab cov ntsiab lus tsis ua haujlwm. Rau cov caj qaum fiber ntau optic cables xa cov teeb liab mus rau ntau pua lossis ntau txhiab tus neeg siv, qhov no cuam tshuam ncaj qha rau lub sijhawm ntev - kev ntseeg siab ntawm lub network.
Dramatically txo lub sij hawm tsim kho- Yog tias tag nrho 288 fibers optical yuav tsum tau txiav thiab rov ua dua -splice, ib pab neeg ua haujlwm fusion splicing yuav xav tau ob peb hnub. Txawm li cas los xij, nrog rau kev tsim hauv kab, tsuas yog cov fibers uas yuav tsum tau muab sib cais (piv txwv li, 48 lossis 96 cores) yog spliced, thaum cov fibers ntxiv yog khaws cia ncaj qha. Qhov no txo cov sij hawm installation los ntawm ob peb hnub mus rau ob peb teev.
khaws cia yav tom ntej expansion yooj- Hnub no koj tsuas yog xav tau ceg 48 fibers, tab sis tag kis koj yuav xav tau ceg 96 ntxiv hauv tib qhov chaw. Qhov no ncaj nraim -los ntawm kev tsim ua kom yooj yim rau yav tom ntej nthuav dav- tsuas yog rov qhib lub thawv sib txuas, txiav qhov ntev uas yuav tsum tau ua los ntawm qhov ua ntej - cov fibers ntsia, thiab splice lawv- tsis tas yuav nteg cov pob tw tshiab.
Spatial thiab Structure Support rau 288-Core Capacity
Ua kom tiav 288-core splice muaj peev xwm thaum tib lub sijhawm muab lub voj voog cia yuav tsum tau ua tib zoo tsim sab hauv. Lub GL-H6-288 splice lub thawv yog tsim los ntawm kev hloov kho polypropylene, muab cov kev cuam tshuam zoo heev, huab cua tsis kam, tiv thaiv corrosion, UV tsis kam, thiab nplaim hluav taws. Nws zoo tiv thaiv cov khoom siv kho qhov muag sab hauv los ntawm kev co, cuam tshuam, nro, torsion, thiab lwm yam kev ntxhov siab. Tsis tas li ntawd, cov khoom no tiv taus qhov degradation ntawm optical cables thiab accessories los ntawm tej yam ntuj tso xws li tshav kub, txias, lub teeb, oxygen, thiab microorganisms.
Sab hauv, lub splice kaw siv tus qauv 12-fiber- ib- tais tsim, haum rau 12 splice tais rau tag nrho cov peev txheej ntawm 288 fibers. Txhua lub tais ntawm nws tus kheej tswj 12 fibers, nrog splicing, coiling, thiab labeling cais. Qhov kev hloov pauv no tso cai rau cov neeg teeb tsa hloov kho kom yooj yim kho tus naj npawb ntawm cov tais raws li xav tau- pib nrog tsuas yog 2-3 lub tais pib, thiab ntxiv ntau ntxiv thaum lub network nthuav dav, tsis tas yuav hloov tag nrho kaw. Cov slack fibers los ntawm lub voj-los ntawm lub cev cable yog coiled nyob rau hauv siab cia qhov chaw nyob rau hauv qab ntawm lub enclosure, lub cev cais tawm ntawm lub splicing cheeb tsam kom meej meej routing thiab tsis muaj kev cuam tshuam.
6-Port Configuration: Adapting mus rau ntau yam Cable Diameters thiab Topologies
Lub rau cable chaw nres nkoj ntawm 288-core hauv -kab splice kaw txuas ntxiv txhim kho nws cov kev hloov pauv hloov pauv. Qhov nruab nrab ob qhov chaw nres nkoj haum rau cov cables nrog txoj kab uas hla ntawm Ø16-25mm, siv rau lub cev hnyav; qhov seem plaub qhov chaw nres nkoj txais cables ntawm Ø10-20mm, rau lub thinner ceg cables. Qhov "dual-}zone" chaw nres nkoj tsim no tso cai rau tib lub kaw kom txuas cov kab sib txawv ntawm cov kab sib txawv -los ntawm cov kab hauv lub cev kom nyias nyias-tsis muaj cov khoom siv ntxiv.
Nyob rau hauv cov nqe lus ntawm topological yooj, lub rau lub chaw nres nkoj txhawb ntau configurations:
1-input-5-output:ib lub cev cable nyob rau hauv, branching mus rau tsib sib txawv kev taw qhia
2-input-4-tso zis:ob lub cev cables (piv txwv li, los ntawm cov chaw ua haujlwm hauv nruab nrab) sib txuas thiab faib mus rau plaub qhov kev qhia
3-input-3-tso zis:peb cables sib ntsib, ua kom yooj yim routing nyob rau hauv complex topologies
Mechanical Sealing thiab IP68: Txhim khu kev tiv thaiv ntawm lub peev xwm siab
Ntau qhov chaw nres nkoj thiab lub peev xwm loj tso qhov kev xav tau ntau dua rau kev ua haujlwm sealing. Lub 288-pin in-line connector cover siv lub tshuab foob cov qauv, siv cov clamping screws kom nruj lub sealing gasket rau waterproof thiab plua plav tiv thaiv, tshem tawm qhov xav tau kev kho cua sov. Lub 304 stainless hlau clamping screws thiab ntxhua khaub ncaws muaj kev tiv thaiv corrosion zoo heev, tswj kev ruaj ntseg clamping quab yuam txawm nyob rau hauv ntub dej, ntsev tsuag, lossis lwm qhov chaw hnyav.
IP68 tiv thaiv kev ntsuas txhais tau hais tias qhov kaw tuaj yeem ua haujlwm hauv qab dej rau lub sijhawm txuas ntxiv yam tsis muaj dej nkag hauv - qhov tseem ceeb rau cov manholes thiab cov kav dej hauv av uas feem ntau ua rau dej nyab. Txawm hais tias tau nruab rau saum huab cua, hauv cov kav dej, hauv qhov manholes, lossis ncaj qha faus, lub 288-core in-line splice kaw tuav ruaj khov kev ua tau zoo ntawm txhua txoj kev teeb tsa.
Xaus
The value of the 288-core straight-through fusion splice box lies in its ability to meet the two core requirements of high-density optical networks with a single device: capacity handling and flexible branching. Nws txoj kev txiav-voj- los ntawm kev tsim ua kom muaj kev ncaj ncees ntawm cov qaum qaum cable; nws 12 splice tais thiab 288-core muaj peev xwm daws cov teeb meem ntawm splicing siab fiber ntau suav; nws rau qhov chaw nres nkoj thiab ntau yam ntawm cable diameters haum rau txoj hauv kev network topologies; thiab nws IP68 txhua yam foob ua kom muaj kev ntseeg siab sab nraum zoov mus ntev.
Raws li siab -ODN ceev txuas ntxiv mus txuas ntxiv mus rau hauv nroog thiab nyob deb nroog, 288 core kab fusion splice lub thawv muaj cov phiaj xwm kev sib txuas lus uas sib xyaw ua ke muaj peev xwm, yoog raws, thiab kev ntseeg siab -tig txhua ceg taw tes ntawm ntau tus qaum qaum qaum mus rau hauv lub fulcrum rau network expansion.
