Ngokubanzi, izixhobo ze-ONU zinokuhlelwa ngokweemeko ezahlukeneyo zesicelo, njenge-SFU, HGU, SBU, MDU, kunye ne-MTU.
1. Ukusasazwa kwe-SFU ONU
Inzuzo yale ndlela yokuthunyelwa kukuba izibonelelo zenethiwekhi zicebile, kwaye zifanelekile kwimizi ezimeleyo kwiimeko ze-FTTH.Inokuqinisekisa ukuba umxhasi unomsebenzi wokufikelela kwibroadband, kodwa ayibandakanyi imisebenzi entsonkothileyo yesango lasekhaya.Kule meko, i-SFU ineendlela ezimbini eziqhelekileyo: zombini i-Ethernet interfaces kunye ne-POTS interfaces.Kuphela ujongano lwe-Ethernet lubonelelwe.Kufuneka kuqatshelwe ukuba kuzo zombini iifom, i-SFU inokubonelela ngemisebenzi ye-coaxial cable ukuququzelela ukufezekiswa kweenkonzo ze-CATV, kwaye ingasetyenziselwa kunye nesango lasekhaya ukuququzelela ukunikezelwa kweenkonzo zexabiso elongezelelweyo.Le meko ikwasebenza kumashishini angafunekiyo ukutshintsha idatha ye-TDM.
2. Ukusasazwa kwe-HGU ONU
Isicwangciso sokusebenzisa i-terminal ye-HGU ONU iyafana ne-SFU, ngaphandle kokuba imisebenzi ye-ONU kunye ne-RG idityanisiwe.Xa kuthelekiswa ne-SFU, inokuqonda ulawulo oluntsonkothileyo kunye nemisebenzi yolawulo.Kule meko yokuthunyelwa, i-interfaces ene-U yakhiwe kwizixhobo ezibonakalayo kwaye ayiboneleli nge-interfaces.Ukuba izixhobo ze-xDSLRG ziyafuneka, iindidi ezininzi zojongano zinokuqhagamshelwa ngokuthe ngqo kuthungelwano lwasekhaya, elilingana nesango lasekhaya eline-EPON uplink interfaces, kwaye isebenza ikakhulu kwi-FTTH izicelo.
3. Ukusasazwa kwe-SBU ONU
Esi sisombululo sokuthunyelwa sifanelekile ngakumbi kubasebenzisi beshishini elizimeleyo ukwakha amanethiwekhi kwimodi yesicelo seFTTO, kwaye isekelwe kwiinguqu zeshishini kwi-SFU kunye ne-HGU yokuthunyelwa kweemeko.Kulo mmandla wokuthunyelwa, inethiwekhi isekela umsebenzi we-terminal yokufikelela kwi-broadband kwaye inikezela abasebenzisi ngeendlela ezahlukeneyo zokudibanisa idatha, kubandakanywa i-El interfaces, i-Ethernet interfaces, kunye ne-POTS interfaces, ukuhlangabezana neemfuno zezoshishino zokunxibelelana kwedatha, unxibelelwano lwezwi, kunye nemigca ezinikeleyo ye-TDM.I-interface e-U-shaped kwimo engqongileyo inokubonelela amashishini ngeentlobo zeempawu zesakhelo sesakhelo, esinamandla ngakumbi.
4. Ukusasazwa kwe-MDU ONU
Isisombululo sokuthunyelwa sisebenza kulwakhiwo lwenethiwekhi yabasebenzisi abaninzi kwiindlela zeFTTC, FTTN, FTTCab, kunye neFTTZ.Ukuba abasebenzisi beshishini abanazo iimfuno zeenkonzo ze-TDM, esi sisombululo sinokusetyenziselwa ukuhambisa uthungelwano lwe-EPON.Esi sisombululo sokuthunyelwa sinokubonelela ngeenkonzo zonxibelelwano lwedatha ye-broadband kubasebenzisi abaninzi, kubandakanywa neenkonzo ze-Ethernet / IP, iinkonzo zeVoIP, kunye neenkonzo zeCATV, kwaye zinamandla okudlulisa idatha.I-port nganye yonxibelelwano inokuhambelana nomsebenzisi wenethiwekhi, ngoko ke ukusetyenziswa kwayo kwenethiwekhi kuphezulu.
5. Ukusasazwa kwe-MTU ONU
Isisombululo sokuthunyelwa kwe-MDU lutshintsho lwezorhwebo olusekelwe kwisisombululo sokuthunyelwa kwe-MDU.Ibonelela ngeenkonzo zonxibelelwano ezininzi, kubandakanya ujongano lwe-Ethernet kunye nojongano lwePOTS, kubasebenzisi bamashishini amaninzi, ukuhlangabezana neemfuno ezahlukeneyo zenkonzo njengelizwi, idatha, kunye nemigca ezinikeleyo ye-TDM.Xa kudityaniswe nesakhiwo slot ukuphunyezwa, imisebenzi etyebileyo kwaye enamandla ishishini inokuphunyezwa.
