1. SFU ONU kev xa tawm
Qhov zoo ntawm hom kev xa tawm no yog tias cov peev txheej hauv lub network muaj cov nplua nuj, thiab nws tsim nyog rau cov tsev neeg ywj pheej hauv FTTH cov xwm txheej.Nws tuaj yeem ua kom ntseeg tau tias tus neeg siv khoom muaj lub luag haujlwm nkag mus siv dav dav, tab sis tsis koom nrog txoj haujlwm nyuaj hauv tsev.Nyob rau hauv ib puag ncig no, SFU muaj ob hom: ob qho tib si Ethernet interfaces thiab POTS interfaces.Tsuas yog Ethernet interfaces tau muab.Nws yuav tsum raug sau tseg tias nyob rau hauv ob daim ntawv, SFU tuaj yeem muab cov coaxial cable ua haujlwm los pab txhawb kev ua tiav ntawm CATV cov kev pabcuam, thiab tseem tuaj yeem siv nrog lub rooj vag hauv tsev los pab txhawb cov kev pabcuam muaj nqis ntxiv.Qhov xwm txheej no tseem siv tau rau cov lag luam uas tsis tas yuav pauv cov ntaub ntawv TDM.
2. HGU ONU xa tawm
Lub HGU ONU lub davhlau ya nyob twg xa tawm lub tswv yim zoo ib yam li SFU, tshwj tsis yog tias ONU thiab RG kev ua haujlwm yog kho vajtse ua ke.Piv nrog SFU, nws tuaj yeem paub ntau txoj kev tswj hwm thiab kev tswj hwm txoj haujlwm.Hauv qhov kev xa tawm no, U-shaped interfaces tau tsim rau hauv cov khoom siv lub cev thiab tsis muab kev cuam tshuam.Yog tias xav tau cov khoom siv xDSLRG, ntau hom kev sib cuam tshuam tuaj yeem txuas ncaj qha rau hauv tsev network, uas yog sib npaug rau lub rooj vag hauv tsev nrog EPON uplink interfaces, thiab feem ntau siv rau FTTH daim ntawv thov.
3. SBU ONU xa tawm
Qhov kev daws teeb meem no yog qhov tsim nyog rau cov neeg siv khoom lag luam ywj pheej los tsim kev sib koom tes hauv FTTO daim ntawv thov hom, thiab ua raws li kev hloov pauv kev lag luam hauv SFU thiab HGU xa tawm scenarios.Hauv qhov chaw xa tawm no, lub network txhawb nqa lub dav hlau nkag mus rau lub davhlau ya nyob twg thiab muab cov neeg siv nrog ntau cov ntaub ntawv sib cuam tshuam, suav nrog El interfaces, Ethernet interfaces, thiab POTS interfaces, ntsib cov lag luam yuav tsum tau ua rau cov ntaub ntawv sib txuas lus, kev sib txuas lus suab, thiab TDM cov kab mob siab rau.U-shaped interface nyob rau hauv ib puag ncig tuaj yeem muab kev lag luam nrog ntau yam cwj pwm ntawm cov qauv qauv, uas muaj zog dua.
4. MDU ONU kev xa tawm
Kev xa tawm cov kev daws teeb meem siv rau kev siv ntau tus neeg siv network hauv FTTC, FTTN, FTTCab, thiab FTTZ hom.Yog tias cov neeg siv kev lag luam tsis muaj qhov yuav tsum tau ua rau TDM cov kev pabcuam, qhov kev daws teeb meem no tuaj yeem siv los xa EPON tes hauj lwm.Qhov kev xa tawm no tuaj yeem muab kev pabcuam kev sib txuas lus dav dav rau ntau tus neeg siv, suav nrog Ethernet / IP cov kev pabcuam, VoIP cov kev pabcuam, thiab CATV cov kev pabcuam, thiab muaj peev xwm xa cov ntaub ntawv muaj zog.Txhua qhov chaw sib txuas lus tuaj yeem cuam tshuam rau tus neeg siv lub network, yog li nws siv network ntau dua.
5. MTU ONU xa tawm
MDU kev xa tawm kev daws teeb meem yog kev hloov pauv lag luam raws li MDU xa tawm kev daws teeb meem.Nws muab ntau yam kev pabcuam cuam tshuam, suav nrog Ethernet interfaces thiab POTS interfaces, rau ntau tus neeg siv kev lag luam, ntsib ntau yam kev pabcuam xws li lub suab, cov ntaub ntawv, thiab TDM cov kab mob siab rau.Thaum ua ke nrog cov qauv siv qhov ua haujlwm, kev ua lag luam nplua nuj thiab muaj zog tuaj yeem ua tiav.
