WiFi 5 ONU yog dab tsi?,
,
LM240TUW5 dual-hom ONU / ONT thov hauv FTTH / FTTO, muab cov ntaub ntawv kev pabcuam raws li EPON / GPON network.LM240TUW5 tuaj yeem sib xyaw ua haujlwm wireless nrog ua tau raws li 802.11 a/b/g/n/ac cov qauv, txhawb 2.4GHz & 5GHz wireless teeb liab ib yam.Nws muaj cov yam ntxwv ntawm kev muaj zog nkag mus rau lub zog thiab kev pabcuam dav.Nws tuaj yeem muab cov neeg siv nrog cov ntaub ntawv sib kis tau zoo dua.Thiab nws muab cov kev pabcuam TV raug nqi nrog 1 CATV Chaw nres nkoj.
Nrog rau qhov ceev txog li 1200Mbps, 4-Port XPON ONT tuaj yeem muab cov neeg siv nrog kev sib tw hauv is taws nem, hu xov tooj hauv internet, thiab kev ua si hauv online.Ntxiv mus, los ntawm kev siv lub kav hlau txais xov sab nraud Omni-kev taw qhia, LM240TUW5 tuaj yeem ua rau muaj ntau yam wireless & rhiab heev, uas ua rau koj tau txais cov teeb liab wireless nyob rau hauv kaum sab xis ntawm koj lub tsev lossis chaw ua haujlwm.Koj tseem tuaj yeem txuas rau TV thiab txhawb koj lub neej.
ONU (Optical Network Unit) yog ib qho khoom siv kho qhov muag siv hauv fiber ntau optic kev sib txuas lus nrog ob txoj haujlwm ntawm "xa" thiab "tau txais".Nws yog ib qho khoom siv hauv lub network kho qhov muag uas txuas kho qhov muag cables rau cov neeg siv khoom siv.Fiber optic kev sib txuas lus yog kev sib txuas lus thev naus laus zis uas siv lub teeb raws li Bellman teeb liab, ONU yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws rau kev sib txuas lus thiab kev sib txuas lus.Piv nrog rau cov khoom siv network txheem, ONU muaj ob yam ntxwv:
Ua ntej, hais txog kev sib txuas ntawm lub cev, ONU siv fiber ntau optic cables es tsis txhob siv cov xov tooj sib txuas.Vim hais tias fiber ntau optic cable muaj kev sib kis ceev, cov ntaub ntawv muaj peev xwm kis tau tus mob, thiab kev sib kis tau ntev, nws yog qhov tsim nyog rau kev xa cov ntaub ntawv ceev thiab ceev ceev.
Qhov thib ob, ONU siv cov thev naus laus zis tshwj xeeb ntawm TDMA (Lub Sijhawm Division Multiple Access) kom ntseeg tau cov ntaub ntawv xa mus rau cov neeg siv sib txawv ntawm lub sijhawm sib txawv kom ntseeg tau tias kev ruaj ntseg thiab kev nyab xeeb ntawm cov ntaub ntawv xa mus.
Kev xav tau
Txoj kev loj hlob ntawm United Nations tau nrawm heev rau txoj kev loj hlob ntawm broadband.Scope feem ntau muaj peb yam nram qab no:
1. Nrhiav qhov dav ntawm lub tsev
Tsis tas li ntawd, cov kev xav tau digital ntawm cov tsev neeg niaj hnub no tau nce ntxiv thiab yuav tsum tau xa cov ntaub ntawv ntau ntxiv rau hauv tsev, uas yuav tsum muaj kev txhawb nqa sai thiab muaj txiaj ntsig.Yav dhau los, ADSL thev naus laus zis muaj kev txwv ntawm kev sib kis ceev, tab sis UN siv fiber ntau optics kom ncav cuag cov neeg siv kawg.Nws txhawb qhov siab tshaj plaws ntawm ntau pua megabits, uas yuav ua tau raws li qhov xav tau ntawm kev xa cov ntaub ntawv loj.
2. Mus txog teb chaws vam meej
Nyob rau hauv cov cheeb tsam nyob deb nroog, tsoos broadband nkag tau yooj yim kom tau raws li cov kev xav tau ntawm cov neeg siv vim muaj tsawg infrastructure.Lub tebchaws United Nations siv cov tshuab fiber ntau optic uas tuaj yeem xa cov ntaub ntawv mus ntev, muab kev pabcuam ceev ceev hauv cov chaw nyob deb nroog thiab ua rau muaj txiaj ntsig zoo rau kev tsim kho vaj tse hauv tebchaws United Nations.
3. Cov qauv kev lag luam
Hais txog kev lag luam, thaum xa cov ntaub ntawv mus rau ntau qhov chaw, ONU siv ntau txoj kev sib txawv thiab sib txawv, uas tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub network, tab sis kuj txhim kho kev ruaj ntseg ntawm cov ntaub ntawv xa mus.tuam txhab.
yav tom ntej
Tam sim no, nrog rau kev txhim kho ntawm 5G, huab xam thiab lwm yam thev naus laus zis, kev sib txuas ib txwm tsis tuaj yeem ua tau raws li qhov xav tau nce ntxiv.Nyob rau hauv sib piv, fiber optic technology muaj qhov zoo ntawm kev kub ceev kis tau tus mob, zoo stability thiab dav bandwidth.Yog li ntawd, ONU raws li cov cuab yeej txuas ntxiv muaj peev xwm dav rau kev txhim kho.Nyob rau yav tom ntej, kev tshawb fawb ntxiv tuaj yeem ua tiav hauv cov hauv qab no:
1. Kev hloov kho tshuab zoo dua los txhim kho kho vajtse thiab rub tawm ceev
Ua kev tshawb fawb txuas ntxiv ntawm cov thev naus laus zis ntsig txog, tsom mus rau kev txhim kho kho vajtse ruaj khov, nce kev sib kis ceev los ntawm kev txo cov khoom siv hluav taws xob, thiab txo qis cov nqi sib txuas hauv network.
2. nthuav dav ntawm daim ntawv thov thiab ntxiv dag zog rau pej xeem cov ntaub ntawv system
UN daim ntawv thov tsis txwv rau tsev thiab lag luam.Nyob rau hauv lub neej yav tom ntej, daim ntawv thov cov cheeb tsam tuaj yeem nthuav dav, thiab cov ntaub ntawv xov xwm hauv zej zog tuaj yeem siv rau hauv thaj chaw xws li tsim lub nroog ntse thiab tsim Internet ntawm Tej Yam los txhim kho cov ntaub ntawv.
3. Txhim khu kev ruaj ntseg network thiab txhim kho cov neeg siv kev ruaj ntseg
Raws li cybercrime ua ntau haiv neeg thiab complex, network kev ruaj ntseg yuav tsum tau ntxiv dag zog rau kom paub meej thiab kev tiv thaiv ntawm cov neeg siv cov ntaub ntawv kis tau tus mob.
