Ua ntej, ua ntej qhia FTTR, peb tsuas nkag siab tias FTTx yog dab tsi.
FTTx yog cov ntawv luv rau "Fiber To The x" rau "fiber to x", qhov twg x tsis yog tsuas yog sawv cev rau qhov chaw uas cov fiber ntau tuaj txog, tab sis kuj suav nrog cov khoom siv kho qhov muag tau teeb tsa ntawm qhov chaw thiab txheeb xyuas thaj chaw uas cov khoom siv network ua haujlwm. . Piv txwv li, "B" hauv FTT B yog cov ntawv luv ntawm Lub Tsev, hais txog cov khoom siv kho qhov muag rau lub tsev, lub tsev kho qhov muag cable rau txoj kev hauv tsev, thaum txuas nrog tus neeg siv los ntawm kev sib tw, thaj chaw uas lubONUpabcuam yog ib lub tsev lossis ib tus neeg siv hauv pem teb.
Lub "H" hauv FTTH yog luv luv rau Tsev, uas yog hais txog cov khoom siv kho qhov muag rau lub tsev, lub tsev kho qhov muag cable rau tus neeg siv lub tsev, thaum nruab rau hauv tus neeg siv lub tsev, thaj tsam ntawm lub tsev.ONUpab yog ib lub tsev.
Tus "R" hauv FTTR yog cov ntawv luv rau Chav, uas yog hais txog qhov kho qhov muag fiber ntau rau 2 lossis ntau chav hauv tus neeg siv lub tsev, thiab nruab rau hauv chav sib txuas, txhua qhovONUpab 1 rau ntau chav hauv tsev.
Thib ob, yog vim li cas thiaj xav tau FTTR, cia peb nkag siab txog cov neeg siv tam sim no WiFi xav tau, xav tau los txhawb daim ntawv thov.
Tam sim no, feem ntau cov neeg siv hauv tsev muaj WiFi los ntawm lubONU/ ONT, muab los ntawm lawv tus kheej Wifi lossis txuas nrog Wifirouter, them los ntawm WiFi teeb liab ntawm lubrouter. Cov khoom siv wifi dav dav hauv kev ua lag luam yog ib zaus thiab dual zaus. Ib zaus tsuas yog txhawb 2.4G zaus band. Txawm hais tias nws tuaj yeem txhawb nqa tus nqi siab tshaj ntawm 300Mbps, qhov kev siv tiag tiag yog qhov phem dua vim tias qhov cuam tshuam ntawm qhov zaus band no kuj loj. Dual-frequency, txhawb rau 2.4G thiab 5G ob zaus bands. 5G WiFi tau raug txhim kho nyob rau hauv tus nqi, tab sis 5G zaus band WiFi teeb liab lub peev xwm mus rau ntawm phab ntsa tsis muaj zog, uas ua rau muaj teeb meem loj rau qee tsev neeg loj, ntau tsev neeg siv.
Tam sim no, muaj tag nrho lub tsev WiFi kev daws teeb meem ntawm kev ua lag luam, feem ntau hauv peb pawg hauv qab no:routercascade tswvyim yog teem lub ntsiabrouterntawmONU, txhua chav yog teem los ntawmrouter, tus tswv thiab qhevrouternrog CAT6 cable. Txwv los ntawm tus naj npawb ntawm tus tswvrouterLAN chaw nres nkoj, tus naj npawb ntawm qhev routers feem ntau tsis tshaj 4, thaum tshaj, qhovhloovyuav tsum tau ntxiv ntawm tus tswvrouter. Vim yog siv cov xov tooj sib txuas, cov tswv yim no tuaj yeem lav qhov Gigabit kev sib txuas ntawm tus tswv thiab qhev txoj kev; Qhov tsis zoo yog tias CAT6 cable yuav tsum tau npaj rau hauv tsev, uas yog qhov nyuaj rau kev siv, yuav cuam tshuam rau qhov tsos, thiab yuav tsum tau txiav.hloovtxhua yam khoom siv WiFi SSID.
Hluav taws xobONUmuab faib ua wired electricONUthiab wireless hluav taws xobONU. CAT6 cables txuas nrog LAN chaw nres nkoj ntawm lubrouter; lub wireless hluav taws xobONUyog wirelessrouterntsaws rau hauv ib lub qhov hluav taws xob hauv tsev (xws li lub qhov (socket) phab ntsa), thiab ib lub xov tooj hluav taws xobONUtuaj yeem ua ke nrog ntau lub wireless ElectricONU. Lub teeb liab ntawm wired ElectricONUthiab Wireless ElectricONUyog 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, thiab lub davhlau ya nyob twg feem ntau yooj yim tso cov kab thaum roaming hauv txhua AP.
Lub subparent routing scheme muaj xws li ib tug niam txivrouterthiab ntau subrouters rau Mesh networking los ntawm WiFi. Vim hais tias cov teeb liab WiFi ntawm lub routers nyuaj tsis mus rau ntawm phab ntsa, lub peev xwm bandwidth ntawm cov tswv yim no cuam tshuam rau ib puag ncig. Muaj ib tug me nyuam thiab leej niam routing khoom, uas siv ob qho tib si WiFi thiab lub hwj chim kab rau kev sib kis, uas txhim kho phab ntsa nkag mus rau lub peev xwm ntawm WiFi mus rau ib tug tej yam, tab sis tag nrho cov bandwidth muaj peev xwm sib txawv yog tseem pom tseeb piv nrog covroutercascade tswvyim.
Peb. Qhov zoo ntawm FTTR
FTTR siv sab hauv tsev WiFi kev pab them nqi, tus tswv thiab qhev kho qhov muag cables, FTTR muaj qhov zoo hauv qab no: (1) npauj npaim kho qhov muag cable los yog zais qhov muag cable piv rau CAT6 cable, zais optical cable tsis cuam tshuam rau sab hauv tsev; (2) lub network ceev tshaj plaws nyob ze cov neeg siv Gigabit tuaj yeem ncav cuag 1000Mbps; (3) ruaj khov network ceev thiab du davhlau ya nyob twg switching ntawm ONU; (4) ntau tshaj 20 xyoo, lub bandwidth yuav luag tsis muaj kev txwv.
Vim qhov zoo li saum toj no ntawm FTTR, ntau tus neeg muag khoom siv tam sim no nqis peev hauv cheeb tsam no, xws li:
Huawei Smart Home = FTTR + Hongmeng
FTTR tag nrho optical WiFi, los ntawm kev sib koom ua ke zoo tshaj plaws ntawmONU, nrog optical fiber ntau siv cable, gigabit broadband, npog txhua chav tsev ntawm tsev neeg, yog kev sib txuas ntawm tsev neeg lub hauv paus, thiab Hongmeng kev khiav hauj lwm yog tag nrho Internet era ntawm ntse davhlau ya nyob twg qhov system, nws yuav siv tau nyob rau hauv watches, mobile xov tooj. , suab, TV thiab lwm yam khoom siv, tseem tuaj yeem kov kev sib txuas, Hongmeng FTTRONU
cia cov terminals loj thiab me me hauv tsev, tsim lub davhlau ya nyob twg super, kev sib txuas nrog ib leeg.
