Kev Sib Txuas Lus Ntiaj Teb Xov Xwm (CWW) Ntawm 2023 Tuam Tshoj Optical Network Seminar muaj nyob rau lub Rau Hli 14-15, Mao Qian, tus kws pab tswv yim ntawm Pawg Saib Xyuas Kev Sib Txuas Lus thiab Technology ntawm Ministry of Industry thiab Information Technology, tus thawj coj ntawm Asia-Pacific Optical Communication Committee, thiab co-chairman ntawm Tuam Tshoj Optical Network Seminar Nws tau taw qhia tiasxPONTam sim no yog qhov kev daws teeb meem tseem ceeb rau Gigabit / 10 Gigabit nkag mus hauv tsev.
PON 10 Gigabit nkag mus hauv tsev
Cov ntaub ntawv qhia tau hais tias txog thaum kawg ntawm lub Plaub Hlis 2023, tag nrho cov naj npawb ntawm Internet tsau broadband cov neeg siv nyob rau hauv kuv lub teb chaws yog 608 lab, ntawm uas tag nrho cov naj npawb ntawm optical fiber nkag FTTH cov neeg siv tau mus txog 580 lab, accounting rau 95% ntawm tag nrho cov. tus naj npawb ntawm cov neeg siv broadband ruaj khov; gigabit cov neeg siv tau mus txog 115 lab. Tsis tas li ntawd, tus naj npawb ntawm cov chaw nres nkoj fiber ntau (FTTH / O) tau mus txog 1.052 billion, suav txog 96% ntawm Internet broadband nkag ports, thiab tus naj npawb ntawm 10G PON chaw nres nkoj nrog Gigabit network kev pabcuam tau mus txog 18.8 lab. Nws tuaj yeem pom tau tias kuv lub teb chaws network infrastructure tau txhim kho tas li, thiab ntau thiab ntau lub tsev thiab kev lag luam tau mus txog gigabit network ceev.
Txawm li cas los xij, raws li kev ua neej nyob txuas ntxiv txhim kho thiab ua kom txawj ntse dua, chaw ua haujlwm hauv online / rooj sib tham / kev sib tham ua haujlwm / khw hauv online / lub neej / kev kawm yuav muaj ntau dua cov kev xav tau rau kev pabcuam network zoo, thiab cov neeg siv yuav muaj kev xav tau ntau dua rau kev sib txuas ceev. Nce tej kev cia siab. "Yog li nws tseem yuav tsum tau nce tus nqi nkag mus tas li, thiab paub txog 10G”Mao Qian taw qhia.
Ua kom tiav1G/ 10 Gigabit nkag mus hauv tsev ntawm qhov loj dua, tsis yog xwbEPON thiab GPONtsis muaj peev xwm, tab sis kuj cov kev pab them nqi ntawm 10GEPON thiab XGPON tsis loj txaus, thiab cov efficiency yog tsawg. Yog li ntawd, yuav tsum muaj PON ceev dua, thiab kev hloov pauv mus rau 50G PON lossis txawm tias 100G PON yog qhov yuav tsum tau hloov tsis tau. Raws li Mao Qian, txiav txim siab los ntawm txoj kev loj hlob tam sim no, kev lag luam yog ntau inclined rau ib leeg-yoj 50G PON, uas txhawb ntau yam technologies ntawm 10G broadband. Cov neeg muag khoom tseem ceeb ntawm kev sib txuas lus hauv tsev twb muaj peev xwm ntawm 50G PON, thiab qee tus neeg xa khoom kuj tau paub txog 100G PON, muab cov xwm txheej yooj yim rau 10G hauv tsev.
Tham txog cov thev naus laus zis ntawm Gigabit thiab 10 Gigabit kev nkag mus hauv tsev kom meej, Mao Qian tau hais tias thaum ntxov li xyoo 2017 Shenzhen Optical Expo, nws tau thov kom muaj kev sib txuas ntawm passive optical network thiab active optical network. Tom qab tus nqi nkag tau los ntawm ib tus neeg siv yuav nce mus rau ib theem (piv txwv li, ntau dua 10G), lub active optical network tej zaum yuav yooj yim dua, yooj yim rau upgrade thiab nqi qis dua passive optical network muab tus nqi siab dua; ntawm Shenzhen Optical Expo hauv 2021 Ntawm OptiNet, nws txawm hais tias cov neeg siv nrog bandwidth ntawm 10 Gigabit thiab saum toj no yuav tsum xav txog cov txheej txheem ntawm bandwidth tshwj xeeb; ntawm OptiNet hauv 2022, nws pom zoo tias cov bandwidth tshwj xeeb tuaj yeem siv tau ntau txoj hauv kev: tshwj xeeb bandwidth rauXG/XGS-PONcov neeg siv, P2P optical fiber tshwj xeeb, NG-PON2 wavelength tshwj xeeb, thiab lwm yam.
"Tam sim no nws zoo nkaus li tias cov phiaj xwm wavelength tshwj xeeb muaj tus nqi ntau dua thiab cov txiaj ntsig zoo, thiab nws yuav dhau los ua kev txhim kho. Tau kawg, ntau cov phiaj xwm tshwj xeeb bandwidth muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab koj tuaj yeem xaiv raws li cov xwm txheej hauv zos. " Mao Qian hais.
