    Combo PON zoo li cas nrog GPON thiab XGPON?

    Post lub sij hawm: Mar-17-2020

    Nrog rau kev siv ntawm "Broadband Tuam Tshoj" thiab "Speed-up thiab nqi-txo" cov tswv yim, Tuam Tshoj 's tsau broadband network peev xwm tau txuas ntxiv txhim kho; neeg siv broadband tau hloov ntawm 10M thiab qis dua mus rau 50M / 100M / 200M, thiab tau hloov zuj zus mus rau Gigabit; broadband network infrastructure Mutual promotion nrog high-txhais video thiab Internet kev pab cuam.

    Txhawm rau ua tiav qhov dhia los ntawm "100M" mus rau "Giga", PON thev naus laus zis yuav tsum tau hloov kho mus rau 10G PON. Ib qho ntawm cov kev txwv tseem ceeb ntawm kev xa tawm ntawm 10G PON yog tus nqi. Tus nqi ntawm 10G PON cov cuab yeej suav nrog tus nqi kho qhov muag modules, chipsets, thiab PCD ntim. Tus nqi ntawm optical modules thiab chipsets yog qhov tseem ceeb.

    Tuam Tshoj Telecom's 2018 10G PON centralized acquisition test thiab bidding feem ntau suav nrog peb ntu: GPON, 10G-EPON, thiab XG-PON cov cuab yeej. Tuam Tshoj Mobile's 2018 GPON cov cuab yeej sau suav nrog GPON, XG-PON, XGS-PON cov cuab yeej. XGS-PON yog thawj zaug.

    GPON tau hloov kho rau XGPON1 lossis XGSPON. Tam sim no, cov kev daws teeb meem tseem ceeb ntawm kev ua lag luam yog kev daws teeb meem sab nraud multiplexer. Hauv qhov kev daws teeb meem no, cov teeb liab ntawm GPON thiab XGPON1 / XGSPON yog multiplexed hauv WDM hom los ntawm kev ntxiv XGPON1 / XGSPON board card, thiab tom qab ntawd ib qho kev sib txuas sab nraud raug xa mus rau cov neeg siv nyob deb. Lub hauv paus ntsiab lus ntawm qhov kev daws teeb meem no yog qhov yooj yim heev, tab sis muaj ntau yam tsis zoo xws li lub sijhawm qhib kev txhim kho ntev, tus nqi siab, ntau yam khoom txhawb nqa, thiab kev ua haujlwm loj. Tsis tas li ntawd, kev taw qhia ntawm ib qho kev sib txuas sab nraud kuj tseem yuav ua rau lub zog kho qhov muag ntxiv, uas yuav muaj kev cuam tshuam. Kev pheej hmoo rau cov neeg siv khoom lag luam uas twb muaj lawm.

    Combo PON yog kev sib txuas ntawm GPON thiab XGPON1 / XGSPON. Nws lub hauv paus ntsiab lus yog kom ib txhij paub txog kev ywj pheej kis tau tus mob thiab txais tos ntawm GPON thiab XGPON1 / XGSPON kho qhov muag teeb liab nyob rau hauv ib qho kev kho qhov muag module, thiab muab plaub sib txawv bearer wavelengths los ntawm ib tug built-in WDM ntaus ntawv.Provides ib tug kho qhov muag fiber interface, uas yuav ua tau sib xws nrog Cov kev pabcuam GPON network uas twb muaj lawm thiab XGPON1 lossis XGSPON cov kev pabcuam tib lub sijhawm, zam kev hloov pauv rau cov qauv network uas twb muaj lawm thiab ntxiv qhov chaw ntxiv rau chav, yog li ua tiav kev hloov kho GPON zoo thiab muaj txiaj ntsig.

    Quad-OSA, plaub qhov chaw nres nkoj kho qhov muag rau Combo PONOLT, integrates ob txheej ntawm transceivers nyob rau hauv ib qho khoom siv kho qhov muag: cov tsoos GPON's 2.5G 1490nm DFB laser thiab 1310nm APD thiab XGPON's 10G 1577nm EML laser thiab 1270nm APD, WDM coupling yog siv rau ob peb mus rau qhov chaw tso zis optical.

    Lub Combo PONOLTraws tu qauv muaj ob txheej txheej txheem, GPON thiab XGPON, nrog ntau yam specifications. Muaj N1, N2a, D1, D2 thiab lwm yam kev qhia tshwj xeeb rau cov peev nyiaj txuas. Hauv cov ntsiab lus yooj yim, txhawm rau txhawm rau sib haum rau 28dB thiab 32dB pob nyiaj siv ntawm ib txwm siv GPON B + thiab C + txuas, XG (S) -PON sib raug rau tib qhov txuas pob nyiaj siv yog qhov zoo tshaj plaws rau kev txhim kho du ntawm GPON rau NGPON. Qhov no yog D1 thiab D2 specifications sib xws rau Combo PON.

    Ob peb xyoos dhau los, cov txheej txheem xa tawm ntawm hybrid integrated Combo PON tes hauj lwm tau qeeb heev. Ib qho ntawm cov laj thawj tseem ceeb yog kev loj hlob ntawm cov khoom siv ntawm ib leeg-fiber bidirectional optical li ntawm Combo PONOLTsab, tshwj xeeb tshaj yog kev loj hlob ntawm high-link pob nyiaj siv kho qhov muag. degree. Rau lub sijhawm ntev, cov txiaj ntsig ntawm cov tuam txhab kho qhov muag khoom hauv cov txheej txheem siab Quad-OSA tau ntsib cov kev cov nyom loj.In thiaj li txhawb nqa daim ntawv thov ntawm Combo PON, txhua tog hauv kev lag luam saw cuam tshuam thiab lees txais txoj kev hloov pauv ntawm kev txo N2a. rau 31dB. Txawm li cas los xij, rau cov tuam txhab kho qhov muag feem ntau tsim cov khoom lag luam PON, cov txiaj ntsig ntawm N2a-raws li cov khoom lag luam Quad-OSA tseem nyob rau hauv siab, thiab cov txiaj ntsig ntawm 32 dB D2 cov khoom siv kho qhov muag qis dua.

    Ntawm qhov tod tes, ntawm daim ntawv thov theem, cov neeg ua haujlwm tau cia siab tias yuav muaj kev loj hlob sai ntawm cov nyiaj siv hluav taws xob siab txuas / kho qhov muag modules. Ntawm 2018 Tuam Tshoj Optical Network / FTTH Lub Rooj Sab Laj tau tuav hauv Beijing thaum Lub Rau Hli xyoo no, cov tswv lag luam xws li Tuam Tshoj Txawb thiab Tuam Tshoj Telecom tseem xav kom pom tseeb tias D2 cov khoom siv kho qhov muag / optical modules tsim cov khoom lag luam uas paub tab kom txhawb nqa tag nrho ntawm Combo PON.
