Nyob rau hauv lub hnub nyoog niaj hnub no, qhov siab siab- ceev cov pob hluav taws xob sib txuas tab sis tsis muaj qhov tseeb}-} tsev (FTH) thiab Fiber - rau -- tsev (FTTB) cov kev pabcuam. Raws li lub passive intermediary nruab nrab ntawm cov muab kev pabcuam thiab xaus {8} {8} sawv cev rau lub cev txoj kev uas kho tshiab taug kev, tsim lub hauv paus ntawm cov tes hauj lwm niaj hnub.
Dab tsi yog lub network kho qhov muag?
Ib qho kho qhov muag tshaj tawm network (ODN) yog lub passion fiber ntau infrastrastructure uas txuas lub chaw pabcuam kho qhov muag (OLT) lossis kho qhov muag) ntawm cov qhua tuaj noj mov. Unlike active networks that require powered equipment throughout the infrastructure, ODN relies entirely on passive components such as optical fibers, splitters, and connectors, making it highly reliable and cost-effective.
Lub luag haujlwm tseem ceeb ntawm ODN yog faib muag tshiab ntawm ib lub ntsiab lus ntawm kev sib txuas ntawm lub chaw ua haujlwm sib txuas los ntawm lub chaw haujlwm tseem ceeb los ua haujlwm rau ntau tus neeg ua haujlwm. Qhov no {- - Kev tsim kho tshuab (pon)
Cov ntsiab lus tseem ceeb ntawm ODN
Lub odn architecture muaj ntau cov Cheebtsam tseem ceeb ua haujlwm hauv kev sib haum xeeb:
1. Cov feeder fiber: qhov no yog lub ntsiab kho qhov muag cable khiav ntawm lub olt hauv lub chaw lis haujlwm faib tawm mus rau 20 knium lossis ntau dua. Nws pabcuam ua cov leeg nyob hauv av rau cov ntaub ntawv kis.
2 Splitters pab tau kev sib qhia ntawm ib qho fiber ntau kev sib txuas nrog cov neeg ua haujlwm ntau.
3. Fiber ntau: cov fiberle ceg tawm ntawm cov splitters rau ntau qhov chaw nkag mus ze rau qhov kawg-}}}}}}}} Cov neeg siv khoom faib khoom.
4. Des Fiber: Qhov kawg ntu sib txuas nrog cov chaw faib khoom ncaj qha rau cov neeg ua haujlwm tau txais ncaj qha rau cov neeg ua haujlwm, xa high- kev pabcuam ceev ceev, lub suab, thiab video kev pabcuam.
5. Kho kom zoo rau cov thawv hluav taws xob: Cov kab sib xyaw ua ke, cov ntsiab lus, thiab kev sib txuas tau kev tswj hwm thiab kev tiv thaiv kev tswj hwm cov kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas nrog kev sib txuas.
6. Fiber Optic Adapters thiab Connectors: Cov khoom sib txuas ua kom pom tseeb thiab sib txuas ntawm cov ntu sib txawv, ua kom muaj teeb meem rau network.
ODN Architecture Hom
ODN kev siv ib txwm ua raws li ob lub hom phiaj ua thawj coj ua:
Centralized Splitting: Cov kev sib tw no siv cov splitters kev loj (1:32 lossis 1:64) nyob ntawm nruab nrab faib. Nws yooj yim ua kom yooj yim network tswj hwm thiab txij nkawm thaum ua qhov zoo tagnrho rau high- ntom nroog thaj chaw.
Faib cov kev cais: Cov qauv no tau ua haujlwm ntau tus me me splitters (1: 4 lossis 1: 8) cov tswv yim muab tso rau thoob plaws hauv lub network. Nws muaj ntau dua kev nthuav dav rau kev nthuav dav network thiab yog tsim tshwj xeeb rau nyob rau hauv nroog lossis nthuav dav nroog.
Qhov Zoo Ntawm Odn Technology
Lub passive xwm ntawm ODN muab cov txiaj ntsig ntau:
Tus nqi efficiency: Tshem tawm qhov kev xav tau rau cov cuab yeej siv muaj nyob hauv lub chaw faib khoom network tseem txo qis kev ua haujlwm thawj zaug thiab cov nqi ua haujlwm txuas ntxiv.
Kev ntseeg siab: nrog tsis muaj lub zog siv zog lossis kev saib xyuas hauv thaj teb, cov kev paub dhau los tsis muaj peev xwm ua tiav thiab xav tau cov chaw tshaj tawm tsawg.
Scalability: cov qauv tsim qauv tso cai rau kev nthuav dav yooj yim raws li cov neeg yuav khoom siv, tsuas yog los ntawm kev ntxiv cov splitters lossis cov fibers.
High bandwidth muaj peev xwm: niaj hnub odn txhawb ntau hom qauv PON, suav nrog gppon, thiab yav tom ntej technologies thiab multi- gigboard kev pabcuam.

Cov kev sib tw thiab kev daws teeb meem niaj hnub
Txawm hais tias nws cov txiaj ntsig, ODN kev xa cov ntsej muag ntsib ntau yam kev cov nyom:
Kev ua haujlwm siab pib: Lub Upfront tus nqi ntawm fiber ntau kev teeb tsa thiab cov khoom sib xyaw tuaj yeem yog ntau. Txawm li cas los xij, pre {{{{-} Connectorized daws thiab txhim kho cov tswv yim tau txo cov nqi xa tawm.
Network Kev Tswj Xyuas Kev Koom Tes: Tsoos Odn Oding kev vam meej nyob rau hauv phau ntawv ntaub ntawv, uas ua rau muaj kev ua yuam kev. Niaj hnub nimno roln daws teeb meem digital ntxig, -} Kev tswj cov khoom siv ntxiv rau txoj haujlwm hauv kev khiav haujlwm.
Kev Txij Nkawm Cov Teeb Meem: Nrig ua yuam kev hauv lub network ua ke keeb kwm kev daws teeb meem. Niaj hnub no cov cuab yeej ntsuas siab tshaj plaws thiab kev tshuaj xyuas ntse soj ntsuam kom sai nrhiav kom tau thiab daws teeb meem.
Lub neej yav tom ntej ntawm ODN
Raws li lub ntiaj teb broadband xav txuas ntxiv nthwv dej, odn thev naus laus zis yog hloov kho kom tau raws li yav tom ntej cov nyom:
Muaj ntau dua kev sib piv: advanced Splitters txhawb 1: 128 lossis ntau dua kev sib piv tau raug tsim los ua cov neeg ua haujlwm ntxiv rau cov neeg ua haujlwm.
Cov ntse OFN: kev sib xyaw ntawm IOT Sensors thiab AI ani analys rau kev twv xyuas thiab tiag {{sij hawm kev txhim kho.
Cov thev naus laus zis siv hluav taws xob: lub zog {- txuag cov qauv thiab cov ntaub ntawv nyob kom muaj kev cuam tshuam los txo kev cuam tshuam ib puag ncig.
5G kev sib xyaw ua ke: ODN yog lub luag haujlwm tseem ceeb hauv 5G Network Backhennaul, txuas xov tooj ntawm tes thiab cov hlwb me me rau cov tes hauj lwm tseem ceeb.
