OLT: Yerekeza kuri optique yumurongo wa terefone dukoresha, kandi nigikoresho cya nyuma cyanyuma gikoreshwa muguhuza fibre optique.
ONU: ONUbivuga umurongo wa optique.ONUigabanijwe cyane mubice bikora optique ya neti hamwe na optique ya optique ya neti.Mubisanzwe, ibikoresho bifite ibikoresho byo kugenzura imiyoboro harimo optique yakira, uplink optique yohereza hamwe na amplifier nyinshi yikiraro yitwa "optique node".
OLT ni ibikoresho byo mu biro muri sisitemu ya EPON passive optique.Nibikorwa byinshi bitanga urubuga, rushobora gushyigikira serivisi za IP na serivisi za TDM icyarimwe.Nigikoresho gishyizwe kumurongo wurusobe rwumujyi wa metropolitani no mugusohoka kwabaturage binjira, bishobora guhuza serivisi zokugeza no kubigeza kumurongo wa IP.
UwitekaONU1001i uplink ihuza ibiro bikuru binyuze ku cyambu cya GEPON, kandi kumanura bishobora gutanga ibyambu bya gigabit Ethernet kubakoresha kugiti cyabo cyangwa abandi bakoresha.Nkigisubizo kizaza cya FTTx,ONU1001i itanga ijwi rikomeye, amakuru yihuta na serivisi za videwo binyuze muri fibre imwe ya GEPON.ONUimikorere: hitamo kwakira amakuru yoherejwe na OLT;Subiza kumurongo no kugenzura imbaraga zoherejwe na OLT;Kandi ugire ibyo uhindura;Umukoresha wa Ethernet amakuru arahishwa kandi yoherejwe kuri uplink icyerekezo cyo kohereza idirishya ryatanzwe na OLT.
