Hauv Suav teb, 100M optical broadband tau nrov, thiab Gigabit era tab tom yuav qhib.Hauv xyoo 2019, Ministry of Industry thiab Information Technology tau tshaj tawm "Ob chav G Ob Chav Lifting, Tib Network Tib Qhov Ceev" ua rau kev sib txuas lus dav dav, thiab txuas ntxiv ua kom nce qib ntawm kev ruaj ntseg broadband Gigabit applications.10G GPON thev naus laus zis tuaj yeem ua tiav los ntawm "pua pua. megabytes" mus "gigabit".10G GPON thev naus laus zis hais txog cov thev naus laus zis xws li XG-PON, XG-PON & GPON Combo, XGS-PON, XGS-PON & GPON Combo.Kev hloov pauv mus rau 10G GPON yuav tsum xav txog cov teeb meem kev sib raug zoo ntawm ntau yam ONUs.
Txhawm rau daws qhov teeb meem uas XG-PON tsis sib haum nrog GPON ONU, ZTE yog thawj zaug los tawm tswv yim thev naus laus zis ntawm Combo PON kom paub txog XG-PON & GPON Combo.Tam sim no, ob-ceev Combo PON thev naus laus zis tau ua tiav. txais tos los ntawm cov neeg siv khoom vim nws qhov zoo sib xws thiab yooj yim.Nws tau dhau los ua cov kev daws teeb meem tseem ceeb rau 10G GPON kev tsim kho thiab muaj kev lag luam muag ntawm qhov loj.
Tam sim no XGS-PON thev naus laus zis tau paub tab, thiab XGS-PON tuaj yeem muab 10G ntawm ntws ntws thiab nqes dej sib luag bandwidth, tab sis XGS-PON OLT tsuas tuaj yeem sib xws nrog XGS-PON thiab XG-PON ob hom ONU, thaum muaj coob tus GPON thiab ONU raug xa mus rau hauv lub network uas twb muaj lawm, thiab kev sib raug zoo ntawm cov network uas twb muaj lawm GPON thiab ONU yuav tsum tau daws thaum lub network hloov mus rau XGS-PON.In thiaj li yuav daws tau qhov teeb meem no, ZTE tau npaj peb-rate Combo technology, uas yog XGS-PON. thiab GPON los siv Combo, uas txhawb nqa kev txhim kho du ntawm GPON rau XGS-PON.
Peb-rate Combo PON thev naus laus zis txoj cai
XGS-PON & GPON's Combo PON kev daws teeb meem yog ib qho kev daws teeb meem hauv multiplexer uas txhawb nqa XGS-PON / XG-PON / GPON peb hom kev sib koom ua ke.Qhov kev lag luam kuj hu nws "peb-ceev Combo PON", uas tau lees paub los ntawm kev lag luam raws li kev lag luam. Kev daws teeb meem zoo tshaj plaws rau kev txhim kho du ntawm GPON rau XGS-PON.
Peb-tus nqi Combo PON siv lub hauv paus ntsiab lus ntawm cov cab kuj sib txawv los ntawm XGS-PON thiab GPON thev naus laus zis, thiab ua ke ob lub wavelengths hauv ib qho khoom siv kho qhov muag kom paub txog kev sib txuas lus ywj pheej thiab txais kev ua haujlwm ntawm GPON thiab XGS-PON optical signals.Qhov peb-ceev Combo. PON kho qhov muag module muaj ib tug built-in combiner uas yuav muab lub nce thiab down plaub wavelengths yuav tsum tau rau splitting XGS-PON thiab GPON.XGS-PON thiab XG-PON siv tib lub wavelength, uas yog ib tug upstream wavelength ntawm 1270 nm thiab ib tug downstream. wavelength ntawm 1577 nm.GPON siv 1310nm upstream wavelength thiab 1490nm downstream wavelength, thiab peb-rate Combo PON optical module paub txog ib leeg-fiber plaub-wavelength kis tau tus mob thiab ua tiav (saib daim duab 1).
Peb-tus nqi Combo PON muab lub peev xwm ntawm GPON terminals sib xws.Vim yog WDM thev naus laus zis, qhov bandwidth muab los ntawm PON chaw nres nkoj yog qhov sib npaug ntawm qhov bandwidth ntawm XGS-PON thiab GPON channels.Thaum peb-rate Combo PON chaw nres nkoj yog ib txhij txuas nrog XG(S)-PON davhlau ya nyob twg thiab GPON lub davhlau ya nyob twg, qhov downlink bandwidth muab los ntawm txhua qhov chaw nres nkoj PON yog 12.5 Gbps (10 Gbps + 2.5 Gbps), thiab uplink bandwidth yog 11.25 Gbps (10 Gbps + 1.25 Gbps).
ZTE's peb-rate Combo PON daws
ZTE's peb-tus nqi Combo PON board txais 8/16-chaw nres nkoj XGS-PON & GPON dual-channel kho vajtse tsim.Ib qho Combo PON chaw nres nkoj sib raug rau ob lub PON MACs (GPON MAC thiab XGS-PON MAC) thiab ob lub cev raws (WDM1r yog koom ua ke rau hauv qhov kho qhov muag module).Hauv kev taw qhia downlink, ob lub downlink nthwv dej tau ua tiav los ntawm PON MAC cais, xa mus rau qhov kho qhov muag module rau multiplexing, thiab tom qab ntawd xa mus rau ONUs sib txawv.XGS-PON ONU tau txais XGS-PON teeb liab, thiab XG-PON ONU tau txais XG.- PON teeb liab, GPON ONU tau txais GPON teeb liab.Nyob rau hauv cov kev taw qhia uplink, GPON thiab XGS-PON siv cov wavelengths sib txawv, lim ua ntej hauv qhov kho qhov muag module, thiab tom qab ntawd txheej txheem nyob rau hauv sib txawv MAC raws.XGS-PON thiab XG-PON siv tib lub wavelength. thiab yuav tsum tau ua DBA teem caij rau tib lub channel.
Qhov chaw nres nkoj ntawm daim npav Combo PON yog 8 lossis 16 chaw nres nkoj.Cov tsos thiab lub cev interface yog ib-rau-ib.Qhov no ua kom yooj yim rau kev tswj hwm txhua hnub thiab kev saib xyuas ntawm cov cuab yeej thiab kev tswj hwm kev tswj hwm.Thaum teeb tsa cov ntaub ntawv tswj xyuas network, koj yuav tsum tau ntxiv ib hom tshiab ntawm pawg thawj coj saib, thiab tus lej GPON, XG-PON, thiab XGS-PON ONUs txhawm rau txheeb xyuas cov ONU hom thiab hloov kho cov channel.Vim tias qhov peb-ceev Combo PON chaw nres nkoj sib raug rau ob lub cev kev sib txuas, cov kev tswj xyuas kev tswj xyuas yog raws li hauv qab no: Lub Combo PON chaw nres nkoj suav nrog ob lub cev: GPON thiab XGS-PON.Kev txheeb xyuas kev ua tau zoo thiab kev tswj lub tswb yuav tsum tau txuas ntxiv raws li tus thawj MIB (Kev Tswj Xyuas Cov Ntaub Ntawv).
Keeb kwm nkag mus rau cov ntaub ntawv ntawm nws tus kheej rau GPON thiab XG(S)-PON raws, nws yog ib qho tsim nyog kom tau txais cov ntaub ntawv ntawm ob lub cev raws tib lub sijhawm.
MIBs cuam tshuam nrog lwm cov kev pabcuam kev teeb tsa thiab kev ua haujlwm thiab kev tswj xyuas kev tswj xyuas tseem tsis hloov pauv.Lawv tau teeb tsa rau Combo PON chaw nres nkoj, thiab Combo PON cia li hloov mus rau cov channel.
Ua tus qauv ntawm 10G PON kev tsim kho
Peb-ceev Combo PON tuaj yeem nkag mus rau XGS-PON, XG-PON thiab GPON peb hom ONUs ntawm qhov kev thov, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg ua haujlwm sib txawv: XGS-PON tuaj yeem siv rau tsoomfwv thiab kev lag luam ntiag tug cov neeg siv, thiab XG -PON tuaj yeem siv rau cov neeg siv hauv tsev Gigabit nkag, GPON yog siv rau cov neeg siv 100M zoo tib yam.
Piv nrog rau sab nraud multiplexer tswvyim, qhov zoo ntawm peb-tus nqi Combo PON yog pom tseeb:
Tsis tas yuav kho ODN, qhov project yog qhov yooj yim.Thaum siv cov multiplexer sab nraud, nws yog ib qho tsim nyog yuav tsum tau ua kom lub multiplexer ntaus ntawv, thiab nws yuav tsum tau kho lub ODN network ntawm ib tug loj scale, uas yog ib qho nyuaj rau siv nyob rau hauv engineering, uas yog ib qho ntawm cov laj thawj tseem ceeb vim li cas XG-PON. nyuaj rau scale.
Qhov kev tso tawm tshiab tsis tau qhia, thiab qhov teeb meem ntawm lub zog kho qhov muag tau daws tau tag nrho.Kev siv cov multiplexer sab nraud yuav ntxiv qhov poob ntxiv 1 ~ 1.5db, uas yog qhov tsis txaus ntseeg rau ntau qhov kev siv hluav taws xob kho qhov muag uas twb nruj lawm, thiab qhov project tsis tuaj yeem siv tau.Qhov peb-tus nqi Combo PON tsis ntxiv qhov poob ntxiv .Thaum tib qib kho qhov muag tau txais yuav, Combo PON tau qhia, thiab cov nyiaj siv hluav taws xob kho qhov muag ntawm ODN network tsis hloov.
Txuag qhov chaw hauv chav tshuab thiab ua kom yooj yim rau kev khiav lag luam thiab kev saib xyuas.Qhov peb-ceev Combo PON optical module integrates functions xws li XG(S)-PON, GPON, thiab WDM1r.Nws tsis ntxiv cov khoom siv ntxiv thiab tsis nyob hauv chav tsev ntxiv, ua kom yooj yim txij nkawm thiab kev tswj xyuas.
Lub OSS yooj yim rau dock, qhib cov txheej txheem tsis hloov, thiab cov kab sab saud raug txiav.Qhov peb-ceev Combo PON txais yuav hom WDM.XG(S)-PON channel thiab GPON channel tau txais kev sib tw nrog lawv cov hom davhlau ya nyob twg.XG(S)-PON thiab GPON uas twb muaj lawm txuas nrog OSS, thiab cov txheej txheem qhib kev pabcuam tseem tsis hloov pauv.Yooj yim qhib, qhov project yog ib qho yooj yim los txiav.
Peb-tus nqi Combo PON kev daws teeb meem tau txais kev pom zoo los ntawm cov neeg ua haujlwm tseem ceeb xws li Txiv kab ntxwv, Telefonica thiab Tuam Tshoj Mobile.Raws li Combo PON kev daws teeb meem thiab kev coj ua lag luam loj, ZTE koom nrog peb-rate Combo PON xeem thiab kev coj ua lag luam ntawm cov tswv lag luam tseem ceeb, thiab txuas ntxiv ua tus 10G GPON kev tsim qauv.
