Nrog rau "Gigabit Optical Network" tau sau rau hauv tsoomfwv daim ntawv tshaj tawm ua haujlwm thawj zaug, thiab cov neeg siv khoom xav tau ntau ntxiv rau kev sib txuas zoo, qhov kev hloov kho qhov muag thib ob "kev hloov pauv" hauv keeb kwm ntawm kuv lub teb chaws broadband tau raug teeb tsa.
Nyob rau hauv kaum xyoo dhau los, Suav cov neeg ua haujlwm tau hloov ntau tshaj 100 xyoo ntawm kev nkag hauv tsev tooj liab xaim rau optical fiber (FTTH), thiab ntawm lub hauv paus no, lawv tau paub txog cov ntaub ntawv ceev ceev rau tsev neeg, thiab ua tiav thawj qhov kev hloov kho qhov muag."Revolution" tau tsim lub hauv paus rau lub zog network.Hauv kaum xyoo tom ntej no, tag nrho-optical fiber ntau (FTTR) ntawm kev sib txuas hauv tsev yuav yog qhov kev taw qhia tshiab thiab traction.Los ntawm kev nqa gigabit mus rau txhua chav, nws yuav tsim cov ntaub ntawv ceev ceev ceev ceev rau tib neeg thiab cov chaw nres tsheb, thiab muab cov kev paub zoo tshaj plaws hauv Broadband yuav ntxiv dag zog rau kev tsim kho lub zog network thiab kev lag luam digital.
Txoj kev sib txawv ntawm tsev gigabit nkag
Raws li lub hauv paus ntawm lub ntiaj teb digitized zuj zus, broadband lub luag haujlwm tsav tsheb hauv kev lag luam kev lag luam txuas ntxiv nthuav dav.Kev tshawb fawb los ntawm World Bank qhia tau hais tias txhua txhua 10% nce nyob rau hauv broadband nkag mus rau qhov nruab nrab GDP loj hlob ntawm 1.38%;"Daim Ntawv Qhia Txog Tuam Tshoj Txoj Kev Txhim Kho Kev Lag Luam Digital thiab Kev Ua Haujlwm (2019)" qhia tias Tuam Tshoj tus 180 lab core-kilometer optical fiber cable network txhawb nqa 31.3 trillion yuan hauv kev lag luam digital.kev loj hlob ntawm.Nrog rau qhov tshwm sim ntawm F5G tag nrho-optical era, broadband tseem tab tom ntsib txoj hauv kev tshiab.
Xyoo no, nws tau thov kom "ua kom muaj kev tsim kho ntawm 5G tes hauj lwm thiab gigabit optical networks, thiab txhawb cov xwm txheej ntawm daim ntawv thov";Nyob rau tib lub sijhawm, "14th Tsib Xyoo Plan" kuj hais txog "txhawb thiab txhim kho gigabit optical fiber networks."Kev txhawb nqa kev sib txuas lus dav dav ntawm 100M mus rau Gigabit tau dhau los ua lub tswv yim tseem ceeb ntawm lub tebchaws.
Rau cov tsev neeg, kev nkag mus rau gigabit kuj yog qhov sib txawv.Tus kab mob ntsws tshiab tam sim no tau txhawb nqa kev loj hlob ntawm kev lag luam tshiab thiab cov qauv tshiab.Tsev neeg tsis yog qhov chaw ntawm lub neej lawm.Nyob rau tib lub sijhawm, nws kuj muaj cov yam ntxwv ntawm kev sib raug zoo xws li tsev kawm ntawv, tsev kho mob, chaw ua haujlwm, thiab ua yeeb yam, thiab tau dhau los ua qhov chaw tsim khoom tiag., Thiab tsev broadband yog qhov txuas tseem ceeb uas txhawb kev txuas ntxiv ntawm tsev neeg cov cwj pwm kev sib raug zoo.
Tab sis tib lub sijhawm, ntau cov ntawv thov kev sib txuas tshiab tau coj ntau yam teeb meem rau hauv tsev broadband.Piv txwv li, thaum saib kev tshaj tawm hauv xov tooj cua, chav kawm online, thiab cov rooj sib tham hauv online, kuv feem ntau ntsib kev hais lus tsis sib haum, poob ntas, thiab tsis muaj suab thiab yees duab.100M tsev neeg maj mam tsis txaus.Txhawm rau txhim kho cov neeg siv khoom kev paub hauv online thiab kev nkag siab ntawm kev tau txais, nws yog ib qho tseem ceeb kom hloov mus rau gigabit bandwidth, thiab tseem ua kom muaj kev cuam tshuam hauv qhov ntev ntawm latency, pob ntawv poob tus nqi, thiab cov kev sib txuas.
Qhov tseeb, cov neeg siv khoom lawv tus kheej kuj yog "kev pov npav nrog lawv txhais taw" - nrog rau kev tshaj tawm cov kev pabcuam gigabit broadband los ntawm cov neeg ua haujlwm hauv ntau lub xeev, kuv lub tebchaws cov neeg siv gigabit tau nkag mus rau lub sijhawm ntawm kev loj hlob sai hauv xyoo dhau los.Kev txheeb xyuas qhia tau tias thaum kawg ntawm 2020, tus naj npawb ntawm cov neeg siv gigabit hauv kuv lub tebchaws yog ze rau 6.4 lab, nrog rau kev loj hlob txhua xyoo ntawm 700%.
FTTR: Ua tus thib ob "khoov" ntawm lub teeb hloov kho
Lub tswv yim ntawm "Txhua chav tuaj yeem ua tiav qhov kev pabcuam Gigabit" zoo li yooj yim, tab sis nws nyuaj.Qhov nruab nrab kis tau tus mob tam sim no yog lub hauv paus loj tshaj plaws txwv kev sib txuas hauv tsev.Tam sim no, tus nqi txwv ntawm mainstream Wi-Fi relays, PLC fais fab modems, thiab network cables feem ntau nyob ib ncig ntawm 100M.Txawm tias super-qeb 5 kab tuaj yeem ncav cuag gigabit.Yav tom ntej, lawv yuav hloov mus rau Qib 6 thiab 7 kab.
Yog li ntawd, nyob rau hauv xyoo tas los no, kev lag luam tau maj mam muab cov kab pom ntawm cov fiber ntau optical.FTTR gigabit all-optical room networking solution raws li PON thev naus laus zis architecture yog qhov kawg hauv tsev sib tham daws teeb meem, vam tias yuav pab kev kawm online, chaw ua haujlwm hauv online, thiab tshaj tawm hauv xov tooj.Cov kev pabcuam tshiab xws li cov khoom thauj, kev lom zem e-kev ua si, thiab kev txawj ntse thoob plaws hauv tsev kom ua tiav cov kev paub dav dav.Tus kws tshaj lij kev lag luam loj tau taw qhia rau C114, "Qhov tseem ceeb ntawm kev txiav txim siab lub peev xwm bandwidth yog cov yam ntxwv zaus ntawm qhov nruab nrab kis.Cov yam ntxwv zaus ntawm optical fibers yog kaum tawm txhiab lub sij hawm ntawm lub network cables.Kev siv lub neej ntawm network cables yog txwv, thaum lub neej kev ua haujlwm ntawm optical fibers yog unlimited.Peb yuav tsum tau saib qhov teeb meem los ntawm txoj kev loj hlob. "
Tshwj xeeb, cov tshuaj FTTR muaj plaub yam tseem ceeb: kev ceev ceev, tus nqi qis, kev hloov kho yooj yim, thiab kev tiv thaiv ib puag ncig ntsuab.Ua ntej ntawm tag nrho cov, optical fiber tau lees paub tias yog qhov kis tau tus mob ceev tshaj plaws.Kev lag luam thev naus laus zis tam sim no tuaj yeem ua tiav qhov muaj peev xwm sib kis tau ntau pua Gbps.Tom qab cov fiber ntau tau xa mus rau hauv tag nrho lub tsev, tsis tas yuav hloov cov kab rau yav tom ntej hloov mus rau 10Gbps 10G network, uas tuaj yeem hais tau ib zaug thiab rau tag nrho.Thib ob, kev lag luam fiber ntau optical yog paub tab thiab kev lag luam ruaj khov.Tus nqi nruab nrab yog qis dua 50% ntawm lub network cable, thiab tus nqi ntawm kev hloov pauv kuj tseem qis dua.
Qhov thib peb, qhov ntim ntawm fiber ntau tsuas yog kwv yees li 15% ntawm cov khoom siv sib txuas zoo tib yam, thiab nws yog qhov me me thiab yooj yim rau rebuilt los ntawm cov yeeb nkab.Nws txhawb pob tshab fiber ntau optical, thiab cov kab qhib tsis ua rau kev kho kom zoo nkauj, thiab cov neeg siv kev lees paub yog siab;muaj ntau txoj kev layout, tsis txwv los ntawm lub tsev tshiab thiab qub, thiab daim ntawv thov qhov chaw loj dua.Thaum kawg, cov khoom siv ntawm cov khoom siv kho qhov muag yog cov xuab zeb (silica), uas yog ib puag ncig zoo thiab ruaj khov dua li tooj liab network cable;Nyob rau tib lub sijhawm, nws muaj peev xwm loj, kev tiv thaiv corrosion, thiab kev pab cuam lub neej ntawm ntau tshaj 30 xyoo.
Rau cov neeg ua haujlwm, FTTR yuav yog ib txoj hauv kev zoo kom ua tiav cov haujlwm sib txawv thiab ua kom zoo ntawm cov kev pabcuam hauv tsev, tsim lub hom phiaj hauv tsev, thiab nce cov neeg siv ARPU;nws tseem yuav muab txoj hauv kev tsim nyog rau kev txhim kho cov tsev ntse thiab kev lag luam tshiab sib cuam tshuam.kev txhawb nqa.Ntxiv rau daim ntawv thov hauv kev sib tham hauv tsev, FTTR kuj tseem tsim nyog rau cov tsev lag luam, chaw ua si thiab lwm cov koom haum hauv cheeb tsam hauv cheeb tsam sib tham, uas tuaj yeem pab cov neeg ua haujlwm txuas ntxiv los ntawm kev sib txuas hauv cheeb tsam mus rau hauv cheeb tsam hauv cheeb tsam los tsim kev sib txuas nrog cov neeg siv khoom.
FTTR nyob ntawm no
Nrog rau kev loj hlob sai ntawm Tuam Tshoj txoj kev kho qhov muag network thiab kev loj hlob ntawm cov saw hlau, FTTR tsis nyob deb, nws yog nyob rau hauv qhov pom.
Thaum lub Tsib Hlis 2020, Guangdong Telecom thiab Huawei tau koom ua ke tsim lub ntiaj teb thawj FTTR tag nrho cov kho qhov muag hauv tsev network daws teeb meem, uas tau dhau los ua lub cim tseem ceeb ntawm qhov thib ob "kuj" ntawm kev hloov kho qhov muag thiab qhov pib tshiab rau kev txhim kho cov kev pabcuam hauv tsev broadband.Los ntawm kev tso cov fibers kho qhov muag rau txhua chav thiab siv Wi-Fi 6 kho qhov muag network chav tsev thiab teeb tsa lub thawv, nws tuaj yeem txhawb nqa 1 txog 16 super networking, kom txhua tus neeg hauv tsev neeg, hauv txhua chav, thiab txhua lub sijhawm muaj super gigabit Broadband kev paub. .
Tam sim no, FTTR kev daws teeb meem raws li PON thev naus laus zis tau tso tawm los ntawm cov neeg ua haujlwm hauv 13 lub xeev thiab nroog suav nrog Guangdong, Sichuan, Tianjin, Jilin, Shaanxi, Yunnan, Henan, thiab lwm yam, thiab cov neeg ua haujlwm hauv ntau tshaj 30 lub xeev thiab nroog tau ua tiav. qhov kev pab cuam tsav tsheb thiab cov kauj ruam tom ntej ntawm kev npaj.
Tsav los ntawm "14th Tsib Xyoo Plan", "kev tsim kho tshiab" thiab lwm yam kev cai zoo, nrog rau kev lag luam xav tau rau cov neeg siv khoom thoob plaws hauv tsev "los ntawm qhov zoo mus rau qhov zoo" thiab "los ntawm qhov zoo mus rau qhov zoo", nws xav tias FTTR yuav nyob rau hauv tsib xyoos tom ntej no.Yuav nkag mus rau 40% ntawm cov tsev neeg hauv Suav teb, txuas ntxiv txhawb txoj kev loj hlob zoo ntawm "Broadband China", qhib qhov chaw ua lag luam ntawm ntau pua billions, thiab tsav kev loj hlob ntawm trillions ntawm cov ntawv thov digital thiab kev lag luam hauv tsev ntse.
Shenzhen HUANET Technology CO., Ltd. Kuj muab GPON OLT, ONU thiab PLC Splitter rau cov neeg ua haujlwm rau ntau qhov haujlwm.
