Centralized vs. Distributed Spliting: Kev txiav txim siab ntawm Architecture Feem ntau cov coj tsis quav ntsej

 

Qhov no yog ntu uas cais cov fiber ntau optic splitter phau ntawv qhia los ntawm cov khoom catalog. Qhov kev xaiv ntawm centralized thiab faib (cascaded) splitting architecture fundamentally hloov PLC splitter ntim koj xav tau, qhov twg koj nruab nws, thiab yuav ua li cas koj network scales lub sij hawm. Cov kev sib tw feem ntau hla qhov no nkaus lossis hais txog nws dhau. Txawm li cas los xij nws yog ib tus neeg tsav tsheb loj tshaj plaws ntawm splitter- ntsig txog kev xa tawm tus nqi thiab kev ua haujlwm nyuaj.

 

Centralized splittingtso ib qho siab - ratio splitter (feem ntau 1 × 32 lossis 1 × 64) ntawm ib qho chaw, feem ntau yog Optical Distribution Terminal (ODT) lossis Fiber Distribution Hub (FDH), nruab nrab ntawm lub hauv paus chaw ua haujlwm thiab cov neeg siv khoom. Ib qhov chaw nres nkoj OLT txuas mus rau ib qho splitter, thiab 32 lossis 64 tus neeg fibers khiav ntawm qhov splitter mus rau txhua ONT.

 

Distributed (cascaded) splittingtheem kev faib hla ob lossis ntau qhov chaw. Ib qho kev teeb tsa zoo siv 1 × 4 PLC splitter nyob ze ntawm lub hauv paus chaw ua haujlwm pub rau plaub qhov chaw qis qis, txhua lub tsev 1 × 8 splitter, ua tiav qhov sib piv 1: 32 tag nrho los ntawm ob theem.

 

 

Txoj kev txawj ntse yog qhov kev sib cais hauv nruab nrab yog qhov yooj yim dua thiab kev faib faib ua kom muaj fiber ntau. Qhov ntawd yog qhov tseeb tab sis tsis tiav. Kev lag luam tiag - tawm matrix suav nrog:

 

Kev siv OLT chaw nres nkoj thiab coj- nce tus nqi.Hauv kev xa tawm FTTH tshiab, thawj zaug - xyoo cov neeg siv khoom ua kom tus nqi feem ntau tseem nyob qis dua 50%, nrog rau ntau qhov chaw cog qoob loo pom 20-40% hauv kev lag luam taug qab los ntawm FTTH Council. Nrog centralized 1 × 32 splitting, txhua qhov chaw nres nkoj OLT ua haujlwm siab tshaj plaws ntawm 32 thaj chaw, tab sis yog tias tsuas yog 10 tau ua haujlwm hauv ib xyoos, qhov chaw nres nkoj tau ua haujlwm ntawm 31% kev siv. Kev faib khoom vaj tse txo qhov no los ntawm kev tso cai rau thawj-theem splitter los ua haujlwm rau thaj chaw dav dua, txhim kho thaum ntxov- theem chaw nres nkoj ua haujlwm. Txawm li cas los xij, qhov thib ob -theem splitters tsim cov txheej txheem ruaj khov ntawm txhua qhov chaw faib khoom tsis hais txog kev noj hauv zos- nce. In dense urban areas with high expected subscriber density and faster take-up trajectories, centralized splitting recovers its port efficiency faster and is generally the better architecture. Nyob rau hauv suburban thiab nyob deb nroog buildouts qhov chaw yog kis thoob plaws qhov deb loj thiab thawj - xyoo ua kom nyob twj ywm qis, faib splitting lub peev xwm los ncua sij hawm thib ob -stage infrastructure peev ua rau muaj kev nkag siab txog nyiaj txiag ntau dua.

 

Kev tshawb fawb qhia tias kev faib khoom tuaj yeem txo cov FDH txee qhov yuav tsum tau muaj peev xwm txog li 75% thiab txiav cov faib fiber ntau suav los ntawm ib qho piv txwv (Sab nraum Cog Cabling). Nyob rau hauv suburban thiab nyob deb nroog deployments qhov chaw yog kis thoob plaws cheeb tsam loj, qhov txo nyob rau hauv lub cev infrastructure yog qhov tseem ceeb.

 

Ncua qhov ntxig poob thiab qhov nws raug nqi li cas.Ob-theem cascading ntxiv qhov poob ntawm ob lub splitters ntxiv rau qhov txuas ntxiv lossis splice interfaces ntawm lawv. A 1 × 4 thawj theem (7.1 dB) ua raws 1 × 8 theem thib ob (10.5 dB) tag nrho 17.6 dB hauv PLC splitter poob ib leeg, piv rau 16.9 dB rau ib zaug -theem 1 × 32. Ntxiv ob qhov txuas txuas ntxiv (0.6 dB) thiab muaj peev xwm muaj ob qhov sib txuas ntxiv (0.2 dB), thiab cov qauv cascaded siv ze li ntawm 1.5 dB ntau dua li qhov nruab nrab. Ntawm tus qauv ib zaug -hom attenuation ntawm 0.3 dB / km, uas 1.5 dB txhais tau hais tias kwv yees li 4-5 km ntawm qhov txo qis tshaj plaws. Hauv cov tes hauj lwm uas twb tau ua haujlwm ze ntawm ntug ntawm lawv cov peev nyiaj siv hluav taws xob, tshwj xeeb tshaj yog kev xa mus rau cov neeg nyob deb nroog nrog cov khoom siv fiber ntau ntev, qhov kev nplua nyob deb tuaj yeem thawb cov neeg nyob deb hauv qab ntawm ONT txais qhov pib.

 

Kev daws teeb meem nyuaj.Centralized splitting muab ib qho chaw nkag mus rau lub cev rau kev sim tag nrho cov kev faib tawm. Ib qho OTDR kab los ntawm ODT tuaj yeem ua tus yam ntxwv ntawm txhua ceg qis. Nrog kev faib tawm, kev sib cais txhaum cai yuav tsum tau nkag mus rau ntau qhov chaw, txhua qhov yuav yog tus ncej- mounted kaw lossis underground pedestal uas xav tau lub tsheb thauj khoom thiab tej zaum yuav muaj ntawv tso cai.

 

Yuav ua li cas qhov no txuas rau PLC splitter ntim xaiv:centralized architectures nyiam LGX cassettes lossis 1U khib-mount units ntawm FDH qhov chaw, vim tias qhov chaw nres nkoj ceev thiab kev tswj hwm ntawm ib qhov chaw tseem ceeb heev. Cov kev faib khoom faib tawm thawb qhov thib ob -theem splitters mus rau qhov chaw sab nraum zoov. ABS lub thawv lossis hom tsis muaj thaiv hauv cov huab cua tsis zoo yog qhov kev xaiv tus qauv. Koj qhov kev sib cais cov qauv txiav txim siab seb hom ntim twg koj yuav yuav hauv ntim. Kev npaj ib qho tsis muaj lwm qhov yog yuav ua li cas cov phiaj xwm xaus nrog txoj cai splitter nti hauv vaj tse tsis raug.

 

Rau cov neeg tsim OLT sab ntawm lub hauv paus PON architecture, qhov chaw nres nkoj suav thiab kev suav nyiaj siv kho qhov muag khi ncaj qha rauGPON OLT system specifications. PLC splitter phua piv koj xaiv txhais tau tias muaj pes tsawg OLT ports koj headend xav tau thiab qhov chaw kho qhov muag txhua qhov chaw nres nkoj yuav tsum txhawb.
