Ngokuvamile, amadivayisi we-ONU angahlukaniswa ngokuya ngezimo zohlelo lokusebenza ezahlukahlukene, njenge-SFU, HGU, SBU, MDU, ne-MTU.
1. Ukuthunyelwa kwe-SFU ONU
Inzuzo yale modi yokuthunyelwa ukuthi izinsiza zenethiwekhi zicebile ngokuqhathaniswa, futhi ifanele imindeni ezimele ezimweni ze-FTTH.Ingaqinisekisa ukuthi iklayenti linomsebenzi wokufinyelela we-broadband, kodwa ayibandakanyi imisebenzi eyinkimbinkimbi yesango lasekhaya.Kule ndawo, i-SFU inezindlela ezimbili ezivamile: kokubili i-Ethernet interface kanye ne-POTS.Kuhlinzekwa ukuxhumana kwe-Ethernet kuphela.Kufanele kuqashelwe ukuthi kuzo zombili izinhlobo, i-SFU ingahlinzeka ngemisebenzi yekhebula le-coaxial ukuze kube lula ukufezeka kwezinsizakalo ze-CATV, futhi ingasetshenziswa nesango lasekhaya ukuze kube lula ukuhlinzekwa kwezinsizakalo ezingeziwe.Lesi simo sisebenza nakumabhizinisi angadingi ukushintshanisa idatha ye-TDM.
2. Ukuthunyelwa kwe-HGU ONU
Isu lokuthunyelwa kwetheminali ye-HGU ONU liyafana ne-SFU, ngaphandle kokuthi imisebenzi ye-ONU ne-RG ihlanganiswe nezingxenyekazi zekhompuyutha.Uma iqhathaniswa ne-SFU, ingabona imisebenzi yokulawula eyinkimbinkimbi kakhulu.Kulesi simo sokusebenzisa, izixhumanisi ezimise oku-U zakhiwe kumadivayisi aphathekayo futhi azihlinzeki ngezindawo zokusebenzelana.Uma amadivayisi e-xDSLRG adingeka, izinhlobo eziningi zezindawo zokusebenzelana zingaxhunywa ngokuqondile kunethiwekhi yasekhaya, okulingana nesango lasekhaya eline-EPON uplink interface, futhi lisebenza ikakhulukazi ezinhlelweni zokusebenza ze-FTTH.
3. Ukuthunyelwa kwe-SBU ONU
Lesi sixazululo sokuphakelwa sifaneleka kakhulu kubasebenzisi bebhizinisi abazimele ukuze bakhe amanethiwekhi kumodi yesicelo se-FTTO, futhi sisekelwe ekushintsheni kwebhizinisi kuzimo zokuthunyelwa ze-SFU ne-HGU.Kule ndawo yokuthunyelwa, inethiwekhi isekela umsebenzi wetheminali yokufinyelela ku-broadband futhi inikeza abasebenzisi izixhumanisi zedatha ezihlukahlukene, okuhlanganisa i-El interfaces, i-Ethernet interface, ne-POTS interface, ehlangabezana nezidingo zebhizinisi zokuxhumana ngedatha, ukuxhumana ngezwi, nemigqa ezinikele ye-TDM.I-interface emise okwe-U endaweni inganikeza amabhizinisi ngezici ezihlukahlukene zesakhiwo sohlaka, esinamandla kakhulu.
4. Ukuthunyelwa kwe-MDU ONU
Isixazululo sokuphakelwa sisebenza ekwakhiweni kwenethiwekhi yabasebenzisi abaningi kumamodi e-FTTC, FTTN, FTTCab, kanye ne-FTTZ.Uma abasebenzisi bebhizinisi bengenazo izimfuneko zezinsizakalo ze-TDM, lesi sixazululo singasetshenziswa futhi ukuphakela amanethiwekhi e-EPON.Lesi sixazululo sokuphakelwa singahlinzeka ngezinsizakalo zokuxhumana kwedatha ye-broadband kubasebenzisi abaningi, okuhlanganisa nezinsizakalo ze-Ethernet/IP, izinsizakalo ze-VoIP, nezinsizakalo ze-CATV, futhi sinamandla anamandla okudlulisa idatha.Imbobo ngayinye yokuxhumana ingahambisana nomsebenzisi wenethiwekhi, ngakho ukusetshenziswa kwayo kwenethiwekhi kuphezulu.
5. Ukuthunyelwa kwe-MTU ONU
Isixazululo sokuphakelwa kwe-MDU wushintsho lwezentengiselwano olusekelwe kusixazululo sokuthunyelwa kwe-MDU.Ihlinzeka ngezinsizakalo eziningi zokusebenzelana, okuhlanganisa i-Ethernet interface kanye ne-POTS, kubasebenzisi bezinkampani eziningi, ehlangabezana nezidingo ezihlukahlukene zesevisi njengezwi, idatha, nemigqa ezinikele ye-TDM.Uma kuhlanganiswe nesakhiwo sokuqaliswa kwe-slot, imisebenzi yebhizinisi ecebile futhi enamandla ingafezeka.
