10G PON Technology xa tawm:
Tam sim no, kev tsim kho dav dav feem ntau yog FTTH, tab sis kev tsim kho ntawm 10G PON tseem yog tus thawj coj los ntawm 10G PON + LAN.Lub nroog xws li Beijing, Shanghai, Guangzhou thiab Shenzhen, qhov twg FTTH raug xa tawm thaum ntxov, tau pib ntsib qhov kev thov rau kev kho dua tshiab ntawm thawj FTTH network.Txawm li cas los xij, vim yog hom me me thiab tus nqi siab ntawm cov terminals hauv 10G PON ONT, 10G PON feem ntau yog siv rau ntawmOLTsab nyob rau hauv lub sij hawm luv luv, thaum lub davhlau ya nyob twg sab tseem tsuas yog siv EPON / GPON terminals kom nce kev txhawb nqa rau GE ports, thiab muab kev pabcuam hauv tsev gigabit rau cov neeg siv tsawg.Nyob rau hauv lub neej yav tom ntej, nrog rau qhov nrov ntawm cov neeg siv high-bandwidth, nrog rau cov nplai ntawm 10G PON terminals thiab tus nqi poob qis, daim ntawv thov teev ntawm 10G PON FTTH yuav maj mam nce.Tam sim no, qhov ntsuas kev xa tawm ntawm 10G EPON hauvOLTsab yog npaj txhij, thiab xa tawm ntawm XG (S) -PON hauvOLTyuav tsum tau paub tab los ntawm Combo PON.Vim muaj qhov txwv tsis pub siv cov txheej txheem, tus nqi ntawm Combo PON yuav tsum siab dua 10G EPON.Tsis tas li ntawd, ua kom yooj yim rau XGPON tus qauv, siv tib lub wavelength li 10G EPON yog li tshem WDM1r los ntawm ODN network.Nws kuj tseem yog ib txoj hauv kev ua tau los txi bandwidth rau kev sib koom ua ke nrog GPON ONT, tab sis nws yuav tsum tau txhawb nqa kev hloov kho ntawm XG-PON tus qauv.
Cov khoom siv ntawm cov chaw tsim khoom uas tsis txhawb 10G PON board daim npav hauv lub network tam sim no yuav tsum tau maj mam hloov, thiab cov khoom siv saum toj no yuav tsum maj mam tshem tawm los ntawm kev siv cov neeg siv tsiv teb tsaws mus rau lwm qhov OLT thiab tag nrho cov khoom hloov.

Tam sim no, PON network tau nqa ntau yam kev pabcuam xws li broadband, suab, IPTV nyob tshaj tawm, IPTV ntawm kev thov thiab kab mob siab.Nyob rau tib lub sijhawm, PON network nqa cov ntaub ntawv tswj xyuas network ntawm PON cov cuab yeej thiab lub rooj vag hauv tsev, thiab tseem tuaj yeem nqa cov xov tooj rov qab thiab cov kev pabcuam prequel yav tom ntej.Nrog rau kev nce ntawm hom kev lag luam thiab cov neeg siv tsawg nyob rau hauv ib qho chaw nres nkoj PON (feem ntau kaum mus rau kaum ob), kev khiav tsheb ntawm ib qho chaw nres nkoj PON muaj cov yam ntxwv ntawm kev muaj zog tam sim ntawd thiab tsis paub tseeb.Thawj txoj hauv kev suav cov tsheb khiav raws li tus qauv kev lag luam tsis raug hloov mus rau cov yam ntxwv ntawm kev tsheb khiav ntawm PON network.Nws tau tawm tswv yim tias PON network yuav tsum tau txais cov tswv yim hauv qab no rau kev xa mus los ua kom lub network bandwidth thiab txhim kho cov neeg siv kev paub.
① Kev nkag tau rau IPTV cov kev pabcuam tau siv tag nrho nrog txheej 2 multicast, nrogOLTdeploying IGMPProxy thiab ONU deploying IGMP Snoop-ing kom txo cov bandwidth txoj hauj lwm ntawm PON chaw nres nkoj.
② Lub broadband access network siv 802.1p-raws li QoS thev naus laus zis, muab qhov tseem ceeb los xyuas kom muaj kev xa mus rau cov kev pabcuam tseem ceeb.
③ Lub rooj vag hauv tsev thiab lub npov saum toj kawg nkaus muaj qhov muag muag, thiab koom tes nrog lub network saib xyuas thiab kev txheeb xyuas qhov system (xws li Huawei uTraffic, ZTE BigDNA, thiab lwm yam) kom paub txog kev saib xyuas zoo ntawm qib lag luam thiab qib network.
PON cov chaw nres nkoj uas tseem tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm bandwidth los ntawm cov tswv yim kev tshaj lij yuav tsum tau hloov kho los ntawm kev kho cov neeg siv khoom faib, txo qhov kev sib cais kho qhov muag thiab hloov kho 10G PON.
Cov saum toj no yog cov lus qhia ntawm 10G PON thev naus laus zis network xa tawm thiabOLTevolution coj los ntawm Shenzhen HDV Phoelectron Technology Co., LTD.Shenzhen HDV Phoelectron Technology Co., Ltd.muaj zog hardware thiab software zog, thiab cov khoom kub muag khoom tseem ceeb yog:
OLTkhoom siv: khib olt, me me olt, compact olt, olt hloov, olt module, kev sib txuas lus olt, thiab lwm yam
ONUkhoom siv: olt onu, ac onu, ntse onu, kev sib txuas lus onu, tsev onu,
Hloov khoom siv: Ethernet hloov, tag nrho-optical hloov, 8 chaw nres nkoj hloov,
100 mbit hloov, hloov kho qhov muag fiber ntau thiab lwm yam, txais tos cov neeg siv khoom rau peb lub tuam txhab kom nkag siab.
