Tsis yog, ibONU(Optical Network Unit) thiab aroutertsis zoo ib yam. Lawv yog cov khoom siv sib txawv nrog cov haujlwm sib txawv hauv lub network. Nov yog qhov kev faib tawm ntawm lawv lub luag haujlwm:
ONU (Optical Network Unit)
Lub hom phiaj: Hloovoptical teeb liablos ntawm koj lub Internet Service Provider's (ISP) fiber ntau -optic kab rau hauvhluav taws xob teeb liabuas koj cov khoom siv hauv zos tuaj yeem siv tau.
Qhov chaw: Feem ntau ntsia ntawm koj qhov chaw (tsev lossis chaw ua haujlwm) ua ib feem ntawm afiber ntau-rau-lub-tsev (FTTH)network.
Muaj nuj nqi:
Ua raws li amodem rau fiber ntau optics(zoo ib yam li cable modem rau coaxial cables).
Feem ntau suav nrog qhov pibrouting/NAT/firewall ntahauv cov khoom siv sib xyaw ua ke (qee zaus hu ua "ONU routers" lossis "gateways"), tab sis nws txoj haujlwm tseem ceeb yog teeb liab hloov dua siab tshiab.
Ntsiab lus: Yog tsis muaj ONU (lossis ONT), koj tsis tuaj yeem txuas mus rau fiber ntau -optic network.
Router
Lub hom phiaj: Direct tshebnruab nrab ntawm koj lub network hauv zos (xws li, cov khoom siv hauv tsev) thiab hauv internet, thiab ntawm cov khoom siv hauv koj lub network hauv zos.
Cov haujlwm tseem ceeb:
Muab IP chaw nyob rau cov khoom siv ntawmDHCP.
MuabNATtso cai rau ntau yam khoom siv los qhia ib tus IP pej xeem.
suav nrogfirewallrau kev ruaj ntseg.
TswjWi-Fi(yog tias nws yog wireless router).
Kev sib txuas: Feem ntau txuas rau modem (lossis ONU) kom nkag mus rau hauv internet.
Kev sib piv
| Yam | ONU | Router |
|---|---|---|
| Lub luag haujlwm tseem ceeb | Fiber teeb liab conversion | Kev tswj hwm kev tsheb khiav hauv network |
| Txheej (OSI Model) | Lub cev / txheej 1 | Network / Txheej 3 |
| Yuav tsum muaj ISP | Yuav tsum tau siv internet fiber ntau | Tsis nruj me ntsis yuav tsum tau (tab sis feem ntau siv) |
| Wi-Fi | Feem ntau tsis yog (tshwj tsis yog ua ke) | Feem ntau suav nrog |
Common Scenario
Cais ONU + Router:
ONU hloov cov teeb liab fiber ntau → txuas ntawm Ethernet mus rau ib tus router standalone → router tsim koj lub network hauv zos.
Ua ke ONU-Router (Gateway):
Muaj ntau ISPs muab ib tugib qho khoom sivuas ua raws li ob qho tib si ONU thiab router (feem ntau nrog Wi-Fi). Qhov no qee zaum hu ua afiber ntau rooj vag.
ONU + Sib cais Router rau kev ua tau zoo dua:
Cov neeg siv feem ntau lov tes taw routing/Wi-Fi ntawm ISP's combo ntaus ntawv ( muab tso rau hauvchoj hom) thiab siv lawv tus kheej siab - router kev ua tau zoo
IbONU zoo li lub modemtab sis rau fiber ntau -optic networks.
A router directs cov ntaub ntawvnruab nrab ntawm koj li thiab hauv internet.
Lawv tuaj yeem yog cov cuab yeej sib cais lossis sib xyaw ua ke hauv ib chav, tab sis lawv cov haujlwm tseem ceeb sib txawv.
Yog tias koj muaj fiber ntau txuas, kojib txwm xav tau ONU/ONT, tab sis koj yuav lossis tsis xav tau ib lub router cais nyob ntawm koj qhov teeb tsa.
