Nrog rau "Gigabit Optical Network" raug sau rau hauv daim ntawv qhia ua haujlwm ntawm tsoomfwv thawj zaug, thiab cov neeg siv khoom xav tau kev sib txuas zoo ntxiv, qhov kev hloov pauv optical thib ob "kev hloov pauv" hauv keeb kwm ntawm kuv lub tebchaws broadband tab tom pib.
Nyob rau kaum xyoo dhau los, cov neeg teb xov tooj Suav tau hloov ntau tshaj 100 xyoo ntawm cov xov tooj liab nkag mus rau hauv cov fiber ntau optical (FTTH), thiab ntawm lub hauv paus no, lawv tau ua tiav tag nrho cov kev pabcuam cov ntaub ntawv ceev ceev rau tsev neeg, thiab ua tiav thawj qhov kev hloov pauv optical. "Kev Hloov Pauv" tau tso lub hauv paus rau lub zog network. Hauv kaum xyoo tom ntej no, tag nrho cov fiber ntau optical (FTTR) ntawm kev sib txuas lus hauv tsev yuav yog qhov kev coj ua tshiab thiab kev rub. Los ntawm kev coj gigabit mus rau txhua chav, nws yuav tsim cov kev pabcuam cov ntaub ntawv ceev ceev ultra-high-speed uas tsom mus rau tib neeg thiab cov davhlau ya nyob twg, thiab muab kev paub zoo Broadband yuav ua kom nrawm dua kev tsim kho lub zog network thiab kev lag luam digital.
Qhov sib txawv ntawm kev nkag mus rau hauv tsev gigabit
Raws li lub hauv paus ntawm lub ntiaj teb digital uas nce zuj zus, broadband lub luag haujlwm tsav tsheb hauv kev lag luam hauv zej zog txuas ntxiv nthuav dav. Kev tshawb fawb los ntawm Lub Tsev Txhab Nyiaj Thoob Ntiaj Teb qhia tau hais tias txhua 10% nce hauv kev nkag mus rau hauv broadband yuav tsav tsheb qhov nruab nrab GDP loj hlob ntawm 1.38%; "Daim Ntawv Dawb ntawm Tuam Tshoj Kev Txhim Kho Kev Lag Luam Digital thiab Kev Ua Haujlwm (2019)" qhia tau hais tias Tuam Tshoj 180 lab core-kilometer optical fiber cable network txhawb nqa 31.3 trillion yuan hauv kev lag luam digital. kev txhim kho ntawm. Nrog rau kev tshwm sim ntawm F5G all-optical era, broadband kuj tseem ntsib cov cib fim tshiab hauv kev txhim kho.
Xyoo no, nws tau hais kom "nce kev tsim kho ntawm 5G networks thiab gigabit optical networks, thiab nplua nuj cov xwm txheej ntawm daim ntawv thov"; tib lub sijhawm, "14th Tsib-Xyoo Txoj Kev Npaj" kuj hais txog "txhawb nqa thiab txhim kho gigabit optical fiber networks." Kev txhawb nqa broadband access networks los ntawm 100M mus rau Gigabit tau dhau los ua ib qho tseem ceeb ntawm lub tebchaws.
Rau cov tsev neeg, kev nkag mus rau gigabit kuj yog qhov sib txawv dav dav. Kev sib kis kab mob ntsws tshiab sai sai tau txhawb nqa kev loj hlob ntawm cov lag luam tshiab thiab cov qauv tshiab. Tsev neeg tsis yog tsuas yog qhov chaw ntawm lub neej xwb. Tib lub sijhawm, nws kuj muaj cov yam ntxwv hauv zej zog xws li tsev kawm ntawv, tsev kho mob, chaw ua haujlwm, thiab chaw ua yeeb yam, thiab tau dhau los ua qhov chaw tsim khoom tiag tiag. , Thiab broadband hauv tsev yog qhov txuas tseem ceeb uas txhawb nqa kev nthuav dav ntawm tsev neeg cov yam ntxwv hauv zej zog.
Tab sis tib lub sijhawm, muaj ntau daim ntawv thov sib txuas lus tshiab tau coj ntau yam kev cov nyom rau hauv tsev broadband. Piv txwv li, thaum saib cov kev tshaj tawm nyob, cov chav kawm online, thiab cov rooj sib tham online, kuv feem ntau ntsib teeb meem stuttering, poob cov thav duab, thiab tsis sib dhos suab thiab video. 100M tsev neeg maj mam tsis txaus. Yuav kom txhim kho cov neeg siv khoom txoj kev paub online thiab kev nkag siab ntawm kev tau txais, nws yog qhov tseem ceeb kom hloov mus rau gigabit bandwidth, thiab txawm tias txuas ntxiv ua kom muaj kev sib tw hauv qhov ntev ntawm latency, packet poob tus nqi, thiab tus lej ntawm kev sib txuas.
Qhov tseeb, cov neeg siv khoom lawv tus kheej kuj "xaiv nrog lawv txhais taw" - nrog rau kev tshaj tawm cov kev pabcuam gigabit broadband los ntawm cov neeg teb xov tooj hauv ntau lub xeev, kuv lub tebchaws cov neeg siv gigabit tau nkag mus rau lub sijhawm ntawm kev loj hlob sai hauv xyoo tas los. Cov ntaub ntawv qhia tias thaum kawg ntawm xyoo 2020, tus lej ntawm cov neeg siv gigabit hauv kuv lub tebchaws ze li ntawm 6.4 lab, nrog rau kev loj hlob txhua xyoo ntawm 700%.
FTTR: Ua tus thawj coj ntawm "kev hloov pauv" thib ob ntawm kev hloov pauv lub teeb
Lub tswv yim ntawm "Txhua chav tuaj yeem ua tiav kev pabcuam Gigabit" zoo li yooj yim, tab sis nws nyuaj. Qhov nruab nrab xa xov tam sim no yog qhov teeb meem loj tshaj plaws uas txwv tsis pub siv thev naus laus zis hauv tsev. Tam sim no, cov kev txwv ntawm cov relays Wi-Fi mainstream, PLC fais fab modems, thiab cov cables network feem ntau yog nyob ib puag ncig 100M. Txawm tias cov kab super-category 5 tuaj yeem ncav cuag gigabit. Yav tom ntej, lawv yuav hloov mus rau Qeb 6 thiab 7 kab.
Yog li ntawd, nyob rau xyoo tas los no, kev lag luam tau maj mam muab txoj kab ntawm kev pom ntawm cov fiber ntau optical. FTTR gigabit all-optical room networking kev daws teeb meem raws li PON technology architecture yog qhov kev daws teeb meem hauv tsev zoo tshaj plaws, vam tias yuav pab kev kawm online, chaw ua haujlwm online, thiab kev tshaj tawm nyob. Cov kev pabcuam tshiab xws li kev thauj khoom, kev lom zem e-sports, thiab kev txawj ntse tag nrho lub tsev kom ua tiav kev paub txog broadband zoo. Ib tug kws tshaj lij hauv kev lag luam laus tau taw qhia rau C114, "Tus yuam sij rau kev txiav txim siab qhov muaj peev xwm bandwidth yog cov yam ntxwv zaus ntawm cov khoom xa tawm. Cov yam ntxwv zaus ntawm cov fiber ntau optical yog kaum txhiab npaug ntawm cov cables network. Lub neej kev siv tshuab ntawm cov cables network yog txwv, thaum lub neej kev siv tshuab ntawm cov fiber ntau optical yog tsis txwv. Peb yuav tsum saib qhov teeb meem los ntawm kev pom kev txhim kho. "
Tshwj xeeb, qhov kev daws teeb meem FTTR muaj plaub yam ntxwv tseem ceeb: ceev ceev, pheej yig, hloov kho yooj yim, thiab kev tiv thaiv ib puag ncig ntsuab. Ua ntej tshaj plaws, fiber ntau optical yog lees paub tias yog qhov nruab nrab kis tau sai tshaj plaws. Cov thev naus laus zis lag luam tam sim no tuaj yeem ua tiav lub peev xwm kis tau ntau pua Gbps. Tom qab cov fiber tau xa mus rau hauv tag nrho lub tsev, tsis tas yuav hloov cov kab rau kev hloov kho yav tom ntej mus rau 10Gbps 10G network, uas tuaj yeem hais tias yog ib zaug thiab rau txhua tus. Qhov thib ob, kev lag luam fiber ntau optical yog mature thiab kev ua lag luam ruaj khov. Tus nqi nruab nrab qis dua 50% ntawm cov cable network, thiab tus nqi ntawm kev hloov pauv kuj qis dua.
Qhov thib peb, qhov ntim ntawm cov fiber ntau tsuas yog li ntawm 15% ntawm cov cable network ib txwm muaj, thiab nws me me thiab yooj yim rov tsim dua los ntawm cov yeeb nkab. Nws txhawb nqa cov fiber ntau pob tshab, thiab kab qhib tsis ua puas rau qhov kho kom zoo nkauj, thiab tus neeg siv kev lees txais siab; muaj ntau txoj kev teeb tsa, tsis txwv los ntawm cov tsev tshiab thiab qub, thiab qhov chaw thov loj dua. Thaum kawg, cov khoom siv raw ntawm cov fiber ntau yog xuab zeb (silica), uas yog tus phooj ywg ib puag ncig thiab ruaj khov dua li cov cable network tooj liab; tib lub sijhawm, nws muaj peev xwm loj, tiv taus corrosion, thiab lub neej ua haujlwm ntau dua 30 xyoo.
Rau cov neeg teb xov tooj, FTTR yuav yog ib txoj hauv kev zoo los ua tiav kev ua haujlwm sib txawv thiab kho kom zoo ntawm cov kev pabcuam broadband hauv tsev, tsim kom muaj lub npe network hauv tsev, thiab nce tus neeg siv ARPU; nws tseem yuav muab cov hauv kev tsim nyog rau kev txhim kho cov tsev ntse thiab kev lag luam sib txuas tshiab. Kev txhawb nqa. Ntxiv rau daim ntawv thov hauv cov xwm txheej network hauv tsev, FTTR kuj tseem tsim nyog rau cov tsev lag luam, cov tiaj ua si thiab lwm yam xwm txheej network hauv zos, uas tuaj yeem pab cov neeg teb xov tooj txuas ntxiv los ntawm cov network dav dav mus rau cov network hauv zos kom tsim kom muaj kev sib txuas nrog cov neeg siv khoom lag luam.
FTTR nyob ntawm no
Nrog rau kev loj hlob sai ntawm Tuam Tshoj lub network optical thiab kev loj hlob ntawm cov saw hlau kev lag luam, FTTR tsis deb, nws nyob hauv qhov muag pom.
Thaum lub Tsib Hlis 2020, Guangdong Telecom thiab Huawei tau koom ua ke tsim lub ntiaj teb thawj FTTR all-optical home network solution, uas tau dhau los ua lub cim tseem ceeb ntawm "kev hloov pauv" thib ob ntawm kev hloov pauv optical thiab qhov pib tshiab rau kev txhim kho cov kev pabcuam broadband hauv tsev. Los ntawm kev tso cov fibers optical rau txhua chav thiab xa Wi-Fi 6 optical network unit thiab set top box, nws tuaj yeem txhawb nqa 1 txog 16 super networking, yog li txhua tus neeg hauv tsev neeg, hauv txhua chav, thiab txhua lub sijhawm muaj kev paub txog super gigabit Broadband.
Tam sim no, FTTR kev daws teeb meem raws li PON thev naus laus zis tau raug tso tawm los ntawm cov neeg teb xov tooj hauv 13 lub xeev thiab nroog suav nrog Guangdong, Sichuan, Tianjin, Jilin, Shaanxi, Yunnan, Henan, thiab lwm yam, thiab cov neeg teb xov tooj hauv ntau dua 30 lub xeev thiab nroog tau ua tiav qhov kev sim thiab kauj ruam tom ntej ntawm kev npaj.
Tsav los ntawm "14th Tsib-Xyoo Txoj Kev Npaj", "kev tsim kho tshiab" thiab lwm yam cai zoo, nrog rau kev thov ua lag luam rau cov neeg siv khoom hauv tsev "los ntawm qhov zoo mus rau qhov zoo" thiab "los ntawm qhov zoo mus rau qhov zoo dua", nws xav tias FTTR yuav nyob rau tsib xyoos tom ntej. Yuav nkag mus rau 40% ntawm cov tsev neeg hauv Suav teb, txuas ntxiv txhawb kev txhim kho zoo ntawm "Broadband Tuam Tshoj", 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 teb xov tooj rau ntau qhov project.
