OLT ni umurongo wa optique, ONU numuyoboro wa optique (ONU), byose nibikoresho byo guhuza imiyoboro ya optique.Nibintu bibiri nkenerwa muri PON: PON (Umuyoboro wa Optive Optique: umuyoboro wa optique).PON (umuyoboro wa optique optique) bivuga (umuyoboro wo gukwirakwiza optique) ntabwo urimo ibikoresho bya elegitoroniki byose hamwe n'amashanyarazi ya elegitoronike, ODN igizwe nibikoresho byoroshye nka optique ya optique (Splitter), ntibisaba ibikoresho bya elegitoroniki bihenze cyane.Umuyoboro mwiza wa optique urimo umurongo wa optique (OLT) washyizwe kuri sitasiyo yo hagati, hamwe nitsinda ryunganira imiyoboro ya optique (ONU) yashyizwe kurubuga rwabakoresha.Umuyoboro wo gukwirakwiza optique (ODN) hagati ya OLT na ONU urimo fibre optique hamwe na pasitifike ya pasiporo cyangwa guhuza.
Inzira na switch ni ibikoresho byo guhanahana amakuru.
ODN (Optical Distribution Network) ni umuyoboro wa FTTH optique ushingiye kubikoresho bya PON.Uruhare rwarwo ni ugutanga umuyoboro mwiza wohereza hagati ya OLT na ONU.Duhereye ku mikorere, ODN irashobora kugabanywamo ibice bine: sisitemu yo kugaburira optique ya kabili, gukwirakwiza optique ya kabili ya sisitemu, gukwirakwiza insinga ya optique ya kabili yo mu nzu hamwe na optique ya fibre optique kuva mubiro bikageza kumpera yumukoresha.
ONT ni igice cyingenzi cya ONU.
FTTB "fibre optique yinyubako", ONU 16 zishyirwa mumasanduku yibice muri koridor.Hano hari ONT 16 muri ONU.Buri ONT isohora umuyoboro wumuyoboro (ikimenyetso cyamashanyarazi) kandi igera kuri buri mukoresha urangije umuyoboro wumuyoboro muri koridor.
FTTH "fibre-to-the-home", shyira ibice 1 kugeza kuri 16 mu gasanduku k'ibice muri koridor, hanyuma ugere kuri buri mukoresha ukoresheje fibre itwikiriye muri koridor, kandi buri mukoresha arangiza ONT.Iringana no gusenya ONU, kugirango ibikoresho bya terefone byegeranye bitagira akagero kubakoresha.
ONT irashobora kumvikana nka ONU ifite icyambu kimwe gusa.
