Kawirikawiri, zipangizo za ONU zimatha kugawidwa m'magulu malinga ndi zochitika zosiyanasiyana zogwiritsidwa ntchito, monga SFU, HGU, SBU, MDU, ndi MTU.
1. Kutumiza kwa SFU ONU
Ubwino wa njira yotumizira deta iyi ndikuti zinthu zomwe zili mu netiwekiyi ndi zolemera, ndipo ndizoyenera mabanja odziyimira pawokha m'malo opezeka ma FTTH. Itha kuwonetsetsa kuti kasitomala ali ndi ntchito yolumikizira intaneti, koma siyimakhudza ntchito zovuta zapakhomo. Munthawi imeneyi, SFU ili ndi njira ziwiri zofanana: ma Ethernet interfaces ndi ma POTS interfaces. Ma Ethernet interfaces okha ndi omwe amaperekedwa. Tiyenera kudziwa kuti m'njira zonse ziwiri, SFU imatha kupereka ntchito za coaxial cable kuti ithandize kukwaniritsa ntchito za CATV, komanso ingagwiritsidwenso ntchito ndi chipata chapakhomo kuti ithandize kupereka ntchito zowonjezera phindu. Izi zikugwiranso ntchito kwa mabizinesi omwe safunika kusinthana deta ya TDM.
2. Kutumiza kwa HGU ONU
Njira yogwiritsira ntchito HGU ONU terminal deployment ndi yofanana ndi SFU, koma ntchito za ONU ndi RG zimagwirizanitsidwa ndi hardware. Poyerekeza ndi SFU, imatha kugwira ntchito zovuta kwambiri zowongolera ndi kuyang'anira. Mu mkhalidwe uwu wogwiritsira ntchito, ma interfaces okhala ndi mawonekedwe a U amamangidwa mu zida zenizeni ndipo sapereka ma interfaces. Ngati zipangizo za xDSLRG zikufunika, mitundu yambiri ya ma interfaces imatha kulumikizidwa mwachindunji ku netiweki yakunyumba, zomwe ndizofanana ndi chipata chakunyumba chokhala ndi ma interfaces a EPON uplink, ndipo makamaka zimagwira ntchito pa mapulogalamu a FTTH.
3. Kutumizidwa kwa SBU ONU
Njira yogwiritsira ntchito deta iyi ndi yoyenera kwambiri kwa ogwiritsa ntchito mabizinesi odziyimira pawokha kuti amange ma network mu FTTO application mode, ndipo imachokera ku kusintha kwa mabizinesi mu SFU ndi HGU deployment scenarios. Mu deployment iyi, network imathandizira ntchito ya broadband access terminal ndipo imapatsa ogwiritsa ntchito ma data interfaces osiyanasiyana, kuphatikiza ma El interfaces, ma Ethernet interfaces, ndi ma POTS interfaces, kukwaniritsa zofunikira za mabizinesi pakulankhulana kwa deta, kulankhulana kwa mawu, ndi mizere yodzipereka ya TDM. Ma interface opangidwa ngati U m'chilengedwe amatha kupatsa mabizinesi mawonekedwe osiyanasiyana a chimango, chomwe chili champhamvu kwambiri.
4. Kutumiza kwa MDU ONU
Njira yothetsera vutoli imagwira ntchito pakupanga ma netiweki ogwiritsa ntchito ambiri mu njira za FTTC, FTTN, FTTCab, ndi FTTZ. Ngati ogwiritsa ntchito mabizinesi alibe zofunikira pa ntchito za TDM, yankho ili lingagwiritsidwenso ntchito pokhazikitsa ma netiweki a EPON. Njira yothetsera vutoli ingapereke ntchito zolumikizirana ndi deta ya broadband kwa ogwiritsa ntchito ambiri, kuphatikiza ntchito za Ethernet / IP, ntchito za VoIP, ndi ntchito za CATV, ndipo ili ndi mphamvu zotumizira deta. Doko lililonse lolumikizirana likhoza kufanana ndi wogwiritsa ntchito netiweki, kotero kugwiritsa ntchito netiweki yake kumakhala kokwera.
5. Kutumiza kwa MTU ONU
Njira yothetsera MDU ndi kusintha kwa malonda kutengera njira yothetsera MDU. Imapereka mautumiki angapo olumikizirana, kuphatikiza ma Ethernet interfaces ndi ma POTS interfaces, kwa ogwiritsa ntchito ambiri amabizinesi, zomwe zimakwaniritsa zofunikira zosiyanasiyana monga mawu, deta, ndi mizere yodzipereka ya TDM. Ikaphatikizidwa ndi kapangidwe ka slot implementation, ntchito zambiri zamakampani zolemera komanso zamphamvu zitha kuchitika.
