Q5: FTTH / FTTO yog dab tsi?
FTTH / FTTO yog dab tsi?
XGSPON (10 Gigabit Symmetric Passive Optical Network) thev naus laus zis tau hloov pauv kev sib txuas lus fiber ntau optic, xa cov ntaub ntawv xa mus nrawm dua, nce bandwidth thiab txhim kho kev ua haujlwm network.Txhawm rau ua kom muaj kev sib txuas tsis sib haum thiab ua tau raws li qhov xav tau ntawm cov ntawv thov niaj hnub no, cov chaw muab kev pabcuam tau siv zog los ua kom tau txais txiaj ntsig zoo dua thiab ntau yam kho qhov muag kab terminals (OLTs).Hauv qhov blog no, peb yuav tshawb nrhiav qhov tshiab tshiab hauv XGSPON thev naus laus zis.
GPON (Gigabit Passive Optical Network) tau tsim lub hauv paus rau kev sib txuas lus siab fiber ntau optic, ua raws li XGPON (10 Gigabit PON) uas muab ntau dua bandwidth.Txawm li cas los xij, XGSPON mus ib kauj ruam ntxiv, ua kom cov ntaub ntawv sib luag ntawm 10 Gbps nyob rau hauv ob qho tib si sab sauv thiab qis qis, ua rau muaj kev sib txuas sai dua, txhim khu kev qha.
Kev lig kev cai, OLTs tau teeb tsa nrog cov chaw nres nkoj tsawg dua.Txawm li cas los xij, kom haum rau cov neeg siv ntau ntxiv thiab cov khoom siv hauv lub ntiaj teb txuas nrog niaj hnub no, OLTs nrog 8 chaw nres nkoj tau dhau los ua neeg nyiam.Qhov chaw nres nkoj nthuav dav no ua rau cov chaw muab kev pabcuam ua haujlwm rau cov neeg siv khoom loj dua, ua kom muaj kev sib txuas ntawm fiber ntau rau cov tib neeg thiab cov lag luam.
Txheej 3 functionality:
Kev koom ua ke txheej txheej 3 ua haujlwm rau hauv OLT qhib lub peev xwm taug kev ntau, yog li txhim kho kev ua haujlwm hauv network thiab kev tswj hwm.Txheej 3 keyboards yog lub luag hauj lwm rau kev taw qhia cov ntaub ntawv pob khoom thoob plaws lub network sib txawv, txhawb nqa cov ntaub ntawv zoo txaus thiab txo qis kev sib koom ua ke.Los ntawm kev koom ua ke Layer 3 kev ua haujlwm rau hauv OLT, cov chaw muab kev pabcuam tuaj yeem txhim kho kev ua haujlwm hauv network, ua kom cov ntaub ntawv muaj txiaj ntsig zoo, thiab txhim kho tag nrho cov neeg siv kev paub.
Qhov tseeb OLT ua ke nrog XGSPON thev naus laus zis nrog 8 chaw nres nkoj thiab Txheej Txheej 3 ua haujlwm, muab ntau yam txiaj ntsig.Cov chaw muab kev pabcuam tuaj yeem txaus siab rau cov neeg siv khoom muaj peev xwm, txhim kho kev ua haujlwm hauv network thiab kev tswj kom yooj yim.Cov neeg siv kawg, ntawm qhov tod tes, tuaj yeem muaj kev nrawm nrawm hauv is taws nem, kev sib txuas txhim khu kev qha, thiab txhim kho kev ua tau zoo rau cov ntaub ntawv siv ntau yam xws li video streaming, gaming online, thiab huab kev pabcuam.
Raws li kev siv thev naus laus zis txuas ntxiv mus, qhov kev xav tau ntawm kev kub ceev, txhim khu kev qha kev sib txuas txuas ntxiv mus.XGSPON thev naus laus zis, nrog nws cov ntaub ntawv muaj peev xwm sib kis tau zoo, ua ke nrog OLTs tshiab nrog 8-chaw nres nkoj thiab Txheej Txheej 3 muaj peev xwm, muab cov kev daws teeb meem kom ua tau raws li cov cai no.Los ntawm kev siv cov kev tsim kho tshiab no, cov neeg muab kev pabcuam tuaj yeem ua tau raws li qhov xav tau ntawm kev sib txuas niaj hnub no, muab cov neeg siv khoom nrog kev ua haujlwm zoo tshaj plaws hauv lub network thiab kev paub siv tsis sib xws.
