OLTni umurongo wa optique,ONUni umuyoboro wa optique (ONU), byose ni ibikoresho byo guhuza imiyoboro ya optique. Nuburyo bubiri bukenewe muri PON: PON (Umuyoboro wa Passive 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 wa optique urimo umurongo wa optique (OLT) yashyizwe kuri sitasiyo yo hagati, hamwe nicyiciro cyo gushyigikira imiyoboro ya optique (ONU) yashyizwe kurubuga rwabakoresha. Umuyoboro mwiza wo gukwirakwiza (ODN) hagati yaOLTnaONUikubiyemo fibre optique hamwe na pasiporo itandukanya cyangwa guhuza.
InziranaGuhindurani 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 yaOLTnaONU. 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 cyaONU.
FTTB “fibre optique ku nyubako”, 16ONUBishyirwa mu gasanduku k'ibice muri koridor. Hano hari ONT 16 muriONU. 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 UwitekaONU, kugirango ibikoresho bya terefone byegeranye bitagira akagero kubakoresha.
ONT irashobora kumvikana nka anONUhamwe n'icyambu kimwe.
