Nthawi zambiri, zida za ONU zitha kugawidwa molingana ndi mawonekedwe osiyanasiyana ogwiritsira ntchito, monga SFU, HGU, SBU, MDU, ndi MTU.
1. Kutumiza kwa SFU ONU
Ubwino wa njira yotumizirayi ndikuti zida zapaintaneti ndizolemera, ndipo ndizoyenera mabanja odziyimira pawokha muzochitika za FTTH.Itha kuwonetsetsa kuti kasitomala ali ndi ntchito yolumikizira burodibandi, koma sichiphatikiza ntchito zovuta zapakhomo.M'malo awa, SFU ili ndi mitundu iwiri yofananira: mawonekedwe onse a Ethernet ndi ma POTS.Ma Ethernet interface okha ndi omwe amaperekedwa.Tiyenera kuzindikira kuti mumitundu yonseyi, SFU ikhoza kupereka ntchito za chingwe cha coaxial kuti zithandizire kukwaniritsidwa kwa ntchito za CATV, komanso zitha kugwiritsidwa ntchito ndi chipata chapakhomo kuti zithandizire kupereka ntchito zowonjezera.Izi zikugwiranso ntchito kwa mabizinesi omwe safunikira kusinthanitsa deta ya TDM.
2. HGU ONU kutumizidwa
The HGU ONU terminal deployment strategy ikufanana ndi SFU, kupatula kuti ntchito za ONU ndi RG ndizophatikizidwa ndi hardware.Poyerekeza ndi SFU, imatha kuzindikira zovuta zowongolera ndi kasamalidwe.Muzochitika zotumizira izi, mawonekedwe owoneka ngati U amapangidwa kukhala zida zakuthupi ndipo samapereka mawonekedwe.Ngati zida za xDSLRG zikufunika, mitundu ingapo yolumikizira imatha kulumikizidwa mwachindunji ndi netiweki yakunyumba, yomwe ili yofanana ndi chipata chapakhomo chokhala ndi EPON uplink interfaces, ndipo imagwiranso ntchito ku mapulogalamu a FTTH.
3. SBU ONU kutumizidwa
Yankho lotumizirali ndiloyenera kwambiri kwa ogwiritsa ntchito mabizinesi odziyimira pawokha kuti apange maukonde mumayendedwe a FTTO, ndipo amachokera pakusintha kwamabizinesi muzochitika za SFU ndi HGU zotumizira.M'malo otumizira awa, maukonde amathandizira ntchito yolumikizira ma burodibandi ndipo amapatsa ogwiritsa ntchito njira zosiyanasiyana zolumikizirana, kuphatikiza ma El interfaces, ma Ethernet olumikizirana, ndi ma POTS, kukwaniritsa zofunikira zamabizinesi kuti azilumikizana ndi data, kulumikizana ndi mawu, ndi mizere yodzipereka ya TDM.Mawonekedwe a U-mawonekedwe achilengedwe amatha kupatsa mabizinesi mitundu yosiyanasiyana yamapangidwe a chimango, omwe ali amphamvu kwambiri.
4. Kutumiza kwa MDU ONU
Njira yothetsera vutoli imagwira ntchito pakupanga maukonde ogwiritsa ntchito ambiri mumitundu ya FTTC, FTTN, FTTCab, ndi FTTZ.Ngati ogwiritsa ntchito mabizinesi alibe zofunikira pazantchito za TDM, yankholi litha kugwiritsidwanso ntchito kuyika maukonde a EPON.Yankho lotumizirali limatha kupereka ntchito zoyankhulirana zamtundu wa Broadband kwa ogwiritsa ntchito angapo, kuphatikiza mautumiki a Ethernet / IP, mautumiki a VoIP, ndi ntchito za CATV, ndipo ali ndi mphamvu zotumizira ma data.Doko lililonse lolumikizirana limatha kufanana ndi wogwiritsa ntchito netiweki, chifukwa chake kugwiritsa ntchito maukonde ndikokwera.
5. Kutumizidwa kwa MTU ONU
Yankho la kutumiza kwa MDU ndikusintha kwamalonda kutengera njira yotumizira MDU.Imapereka mautumiki angapo, kuphatikiza ma Ethernet polumikizira ndi ma POTS, kwa ogwiritsa ntchito mabizinesi angapo, kukwaniritsa zofunikira zosiyanasiyana monga mawu, data, ndi mizere yodzipereka ya TDM.Mukaphatikizidwa ndi kachitidwe ka slot, ntchito zamabizinesi olemera komanso zamphamvu zitha kuchitika.
