I-OLT: Ibhekise kutheminali ye-optical line esiyisebenzisayo, futhi iyisisetshenziswa sokugcina esisetshenziswa ukuxhuma isiqu se-fiber optical.
I-ONU: I-ONUibhekisela kuyunithi yenethiwekhi yokubona.I-ONUihlukaniswe kakhulu ibe iyunithi yenethiwekhi ye-optical esebenzayo kanye neyunithi yenethiwekhi ye-passive optical.Ngokuvamile, okokusebenza okufakwe ukuqapha kwenethiwekhi okuhlanganisa isitholi se-optical, i-uplink optical transmitter kanye nama-amplifiers amaningi amabhuloho kubizwa ngokuthi "i-optical node".
I-OLT iyimishini yehhovisi kuhlelo lwenethiwekhi ye-EPON passive optical network.Kuyinkundla yokuhlinzeka ngezinsizakalo eziningi, engasekela izinsizakalo ze-IP kanye nezinsizakalo zendabuko ze-TDM ngasikhathi sinye.Kuyidivayisi ebekwe emaphethelweni enethiwekhi yendawo yedolobha elikhulu nasekuphumeni kwenethiwekhi yokufinyelela umphakathi, engahlanganisa izinsiza zokufinyelela futhi iwahambise kunethiwekhi ye-IP ngokulandelanayo.
II-ONUI-1001i uplink ixhuma ehhovisi eliphakathi ngembobo ye-GEPON, futhi i-downlink inganikeza amachweba we-gigabit Ethernet kubasebenzisi ngabanye noma abanye abasebenzisi.Njengesixazululo esizayo se-FTTx,I-ONUI-1001i inikeza ngezwi elinamandla, idatha yesivinini esiphezulu namasevisi wevidiyo nge-GEPON ye-fiber eyodwa.I-ONUumsebenzi: khetha ukuthola idatha ethunyelwe yi-OLT;Phendula emiyalweni ehlukahlukene kanye neyokulawula amandla ethunyelwe yi-OLT;Futhi wenze izinguquko ezihambisanayo;Idatha ye-Ethernet yomsebenzisi ifakwe kunqolobane futhi ithunyelwa endaweni ye-uplink ewindini lokuthumela elinikezwe i-OLT.
