1, Ua ntej qhia FTTR, cia peb nkag siab luv luv tias FTTx yog dab tsi.
FTTx yog cov ntawv luv rau "Fiber To The x", xa mus rau "fiber to x", qhov twg x tsis tsuas yog sawv cev rau qhov chaw uas cov fiber ntau tuaj txog, tab sis kuj suav nrog cov khoom siv kho qhov muag teeb tsa ntawm qhov chaw ntawd, thiab qhia txog thaj chaw tau txais kev pab los ntawm cov khoom siv network. Piv txwv li,
Cov ntawv luv "B" hauv FTTB yog Lub Tsev, uas yog hais txog fiber ntau optic cable los ntawm lub tsev mus rau lub tsev, sab hauv tsev fiber ntau optic cable nteg rau txoj kev hauv tsev, thiab txuas nrog cov neeg siv los ntawm kev sib tw twisted cable. Qhov chaw pabcuam los ntawm cov miv optical yog ib lub tsev lossis ib tus neeg siv hauv pem teb.
Tus "H" hauv FTTH yog cov ntawv luv rau "Tsev", uas yog hais txog fiber ntau optic cable los ntawm tsev, sab hauv fiber optic cable yog nteg tawm mus rau tus neeg siv lub tsev, thiab cov miv optical yog ntsia ntawm tus neeg siv lub tsev. Qhov chaw pabcuam los ntawm tus miv optical yog ib lub tsev.
Cov ntawv luv "R" hauv FTTR hais txog kev sib txuas ntawm fiber ntau optic rau ob lossis ntau chav hauv cov neeg siv lub tsev, thiab kev teeb tsa ntawm cov miv kho qhov muag hauv cov chav sib txuas. Txhua tus miv kho qhov muag ua haujlwm ib mus rau ntau chav hauv tsev.
2, Yog li vim li cas peb thiaj xav tau FTTR? Cia peb nkag siab txog tus neeg siv tam sim no cov kev xav tau ntawm WiFi, uas tsav cov ntawv thov.
Tam sim no, feem coob ntawm cov neeg siv hauv tsev 'hauv tsev WiFi nkag los ntawmONU/ONT, muab los ntawm lawv tus kheej WiFi lossis txuas nrog WiFirouter, them los ntawm router lub teeb liab WiFi. Muaj ob hom WiFi davhlau ya nyob twg hauv kev ua lag luam: ib zaus thiab dual zaus. Qhov ib zaus tsuas yog txhawb nqa 2.4G zaus band, thiab txawm hais tias nws tuaj yeem txhawb nqa qhov siab tshaj plaws ntawm 300Mbps, qhov kev siv tiag tiag yog qhov phem dua vim muaj kev cuam tshuam loj hauv cov zaus no. Dual zaus, txhawb nqa 2.4G thiab 5G zaus bands. 5G WiFi tau txhim kho hauv kev nrawm, tab sis lub peev xwm ntawm 5G band WiFi cov cim kom dhau los ntawm cov phab ntsa tsis muaj zog, uas ua rau muaj kev tsis yooj yim rau qee cov tsev neeg loj thiab ntau tus neeg siv.
Tam sim no, muaj peb yam tseem ceeb ntawm tsev dav dav WiFi kev pab them nqi kho mob ntawm kev ua lag luam: lubroutercascade scheme yog teem ib tug tswvrouternyob rau ntawm qhov kho qhov muag miv, thiab txhua chav yog nruab nrog ib tug qhevrouter. Tus tswv thiab qhev routers txuas nrog siv Qeb 6 cables. Vim muaj kev txwv ntawm tus naj npawb ntawm LAN chaw nres nkoj ntawm lub ntsiabrouter, tus naj npawb ntawm cov routers theem nrab feem ntau tsis tshaj 4. Yog tias qhov no dhau qhov kev txwv, yuav tsum tau ntxiv cov keyboards ntxiv ntawm lub ntsiab.router. Vim yog siv cov kev sib txuas ntawm kev sib txuas, cov tswv yim no tuaj yeem ua kom muaj kev sib txuas ntawm gigabit ntawm tus tswv thiab qhev txoj kev; Qhov tsis zoo yog tias Qeb 6 cables yuav tsum tau muab tso rau hauv lub tsev, uas muaj qee yam teeb meem kev siv thiab yuav cuam tshuam rau kev zoo nkauj. Tsis tas li ntawd, nws yog qhov nyuaj rau txiavhloovWiFi SSID ntawm txhua lub cuab yeej.
Cov miv fais fab tau muab faib ua cov miv fais fab thiab cov miv tsis muaj zog. Txuas lub xov tooj fais fab mus rau LAN chaw nres nkoj ntawm tusroutersiv hom 6 cable; Lub wireless fais fab miv yog wirelessrouteruas tuaj yeem ntsaws rau hauv txhua lub qhov hluav taws xob hauv tsev (xws li lub qhov hluav taws xob ntawm phab ntsa), thiab lub tshuab hluav taws xob xaim hluav taws xob tuaj yeem ua ke nrog ntau lub tshuab hluav taws xob wireless rau kev siv. Lub teeb liab nruab nrab ntawm wired fais fab miv thiab wireless fais fab miv kis tau los ntawm cov kab hluav taws xob, thiab lub network ceev tau cuam tshuam zoo heev los ntawm qhov zoo ntawm cov kab hluav taws xob sab hauv tsev rau cov neeg siv. Tsis tas li ntawd, cov terminals feem ntau muaj feem cuam tshuam thaum roaming hauv ntau APs.
Txoj kev qhia menyuam mus rau menyuam muaj xws li ib tug niam txivrouterthiab ntau tus me nyuam routers, thiab txhuaroutertuaj yeem ua meshed los ntawm WiFi. Vim qhov nyuaj ntawm kev tsis dhau ntawm phab ntsa rau WiFi teeb liab ntawm routers, lub peev xwm bandwidth ntawm cov tswv yim no cuam tshuam rau ib puag ncig. Muaj cov noob thiab niam routing cov khoom siv WiFi thiab cov kab hluav taws xob rau kev sib kis ntawm tus menyuam thiab niam routers ib txhij, uas tau txhim kho phab ntsa nkag mus rau ntawm WiFi mus rau qee yam. Txawm li cas los xij, tag nrho lub peev xwm bandwidth tseem lags tseem ceeb piv rauroutercascade tswvyim.
3, Qhov zoo ntawm FTTR
FTTR siv ib lub ntsiab kho qhov muag cable thiab ntau tus qhev optical cables rau sab hauv tsev WiFi kev pab them nqi. Lub ntsiab thiab qhev kho qhov muag cables txuas nrog npauj npaim los yog zais qhov muag cables. Piv nrog rau cov tswv yim saum toj no, FTTR muaj qhov zoo hauv qab no: (1) npauj npaim los yog cov kab hluav taws xob zais hluav taws xob yooj yim dua rau hauv chav kawm 6 cables, thiab kev tso cov kab hluav taws xob zais zais tsis cuam tshuam rau kev zoo nkauj sab hauv tsev; (2) Qhov siab tshaj plaws network ceev nyob ze txhua tus miv optical rau cov neeg siv gigabit tuaj yeem ncav cuag 1000Mbps; (3) ruaj khov network ceev, ruaj khov davhlau ya nyob twg hloov ntawm optical miv; (4) Lub neej ntev ntawm fiber ntau optical tshaj 20 xyoo, thiab bandwidth yuav luag tsis kawg.
Vim yog qhov zoo tshaj plaws ntawm FTTR, ntau lub tuam txhab tsim khoom tam sim no nqis peev hauv daim teb no, xws li:
Huawei Tsev automation = FTTR + Hongmeng
FTTR tag nrho-optical WiFi, los ntawm kev sib xyaw ua ke zoo tshaj plaws ntawm tus tswv thiab qhev kho qhov muag miv, siv cov khoom siv kho qhov muag tsis siv lub network cable los npog gigabit broadband rau txhua chav tsev ntawm tsev neeg, uas yog lub hauv paus kev sib txuas ntawm Tsev automation. Lub Hongmeng operating system yog lub ntse davhlau ya nyob twg kev khiav hauj lwm nyob rau hauv lub era ntawm Internet ntawm txhua yam, uas yuav siv tau nyob rau hauv watches, mobile xov tooj, suab, TVs thiab lwm yam khoom siv, thiab kuj yuav tsum tau kev cob cog rua ntawm kov, tsim ib tug super davhlau ya nyob twg thiab txuas. nrog ib leeg.
Lub network kub muag khoom ntawm Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. npog ntau homONUseries khoom, nrog rau ACONU/ kev sib txuas lusONU/ ntseONU/ lub thawvONU, thiab lwm yam saum toj noONUseries cov khoom siv tuaj yeem siv rau kev xav tau hauv network hauv ntau yam xwm txheej. Zoo siab txais tos txhua tus tuaj thiab muaj kev nkag siab ntau ntxiv txog cov khoom.
