Ngokuvamile, amadivayisi e-ONU angahlukaniswa ngokwezimo ezahlukahlukene zohlelo lokusebenza, njenge-SFU, HGU, SBU, MDU, kanye ne-MTU.
1. Ukuthunyelwa kwe-SFU ONU
Inzuzo yale ndlela yokusabalalisa ukuthi izinsiza zenethiwekhi zicebile, futhi zifanele imindeni ezimele ezimweni ze-FTTH. Ingaqinisekisa ukuthi iklayenti linomsebenzi wokufinyelela i-broadband, kodwa ayibandakanyi imisebenzi eyinkimbinkimbi yesango lasekhaya. Kulesi simo, i-SFU inezindlela ezimbili ezivamile: zombili izixhumi ze-Ethernet kanye nezixhumi ze-POTS. Kunikezwa izixhumi ze-Ethernet kuphela. Kufanele kuqashelwe ukuthi kuzo zombili izinhlobo, i-SFU ingahlinzeka ngemisebenzi yekhebula le-coaxial ukuze kube lula ukufezwa kwezinsizakalo ze-CATV, futhi ingasetshenziswa nesango lasekhaya ukuze kube lula ukuhlinzekwa kwezinsizakalo ezengeziwe. Lesi simo sisebenza nakumabhizinisi angadingi ukushintshanisa idatha ye-TDM.
2. Ukuthunyelwa kwe-HGU ONU
Isu lokufakwa kwe-terminal ye-HGU ONU lifana ne-SFU, ngaphandle kokuthi imisebenzi ye-ONU ne-RG ihlanganiswe nehadiwe. Uma iqhathaniswa ne-SFU, ingafeza imisebenzi yokulawula nokuphatha eyinkimbinkimbi kakhulu. Kulesi simo sokufakwa, izixhumi ezibunjwe ngo-U zakhiwe kumadivayisi angokoqobo futhi azihlinzeki ngezixhumi ezibunjiwe. Uma kudingeka amadivayisi e-xDSLRG, izinhlobo eziningi zezixhumi zingaxhunywa ngqo kunethiwekhi yasekhaya, okulingana nesango lasekhaya elinezixhumi ezibunjiwe ze-EPON, futhi ikakhulukazi kusebenza kuzinhlelo zokusebenza ze-FTTH.
3. Ukuthunyelwa kwe-SBU ONU
Lesi sixazululo sokusabalalisa sifaneleka kakhulu kubasebenzisi bebhizinisi abazimele ukwakha amanethiwekhi kumodi yohlelo lokusebenza lwe-FTTO, futhi sisekelwe ezinguqukweni zebhizinisi ezimweni zokusabalalisa ze-SFU kanye ne-HGU. Kulesi simo sokusabalalisa, inethiwekhi isekela umsebenzi we-terminal yokufinyelela kwe-broadband futhi inikeza abasebenzisi izixhumi zedatha ezahlukahlukene, kufaka phakathi izixhumi ze-El, izixhumi ze-Ethernet, kanye nezixhumi ze-POTS, ezihlangabezana nezidingo zebhizinisi zokuxhumana kwedatha, ukuxhumana ngezwi, kanye nemigqa enikezelwe yi-TDM. Isixhumi esinomumo we-U endaweni singanikeza amabhizinisi izici ezahlukahlukene zesakhiwo sohlaka, esinamandla kakhulu.
4. Ukufakwa kwe-MDU ONU
Isixazululo sokusabalalisa sisebenza ekwakhiweni kwenethiwekhi yabasebenzisi abaningi kumamodi e-FTTC, FTTN, FTTCab, kanye ne-FTTZ. Uma abasebenzisi bebhizinisi bengenazo izidingo zezinsizakalo ze-TDM, lesi sixazululo singasetshenziswa futhi ukusabalalisa amanethiwekhi e-EPON. Lesi sixazululo sokusabalalisa singahlinzeka ngezinsizakalo zokuxhumana kwedatha ye-broadband kubasebenzisi abaningi, kufaka phakathi izinsizakalo ze-Ethernet / IP, izinsizakalo ze-VoIP, kanye nezinsizakalo ze-CATV, futhi sinamakhono anamandla okudlulisa idatha. Imbobo ngayinye yokuxhumana ingahambisana nomsebenzisi wenethiwekhi, ngakho-ke ukusetshenziswa kwayo kwenethiwekhi kuphakeme.
5. Ukuthunyelwa kwe-MTU ONU
Isixazululo sokufakwa kwe-MDU siwushintsho lwezentengiselwano olusekelwe kwisisombululo sokufakwa kwe-MDU. Sihlinzeka ngezinsizakalo eziningi zesikhombimsebenzisi, kufaka phakathi izikhombimsebenzisi ze-Ethernet kanye nezikhombimsebenzisi ze-POTS, kubasebenzisi abaningi bebhizinisi, sihlangabezana nezidingo zesevisi ezahlukahlukene njengezwi, idatha, kanye nemigqa enikezelwe ku-TDM. Uma kuhlanganiswa nesakhiwo sokusetshenziswa kwesikhala, imisebenzi yebhizinisi ecebile nenamandla ingafezeka.
Isikhathi sokuthunyelwe: Disemba-07-2023
