1. AP, irutha engenantambo,idlulisa amasignali enethiwekhi ngamapheya asontekile.Ngokuhlanganiswa kwe-AP, iguqula amasignali kagesi abe amasignali omsakazo futhi iwathumele ngaphandle.
2. I-ONU (Optical Network Unit)iyunithi yenethiwekhi ye-optical.Imishini yenethiwekhi ye-PON, i-PON isebenzisa i-fiber optical eyodwa ukuze ixhume ku-OLT, bese i-OLT ixhunywe ku-ONU.I-ONU inikeza idatha, i-IPTV (I-Interactive Internet Television), izwi nezinye izinsiza.Imbobo ye-PON lapha ibhekisela echwebeni ku-OLT.Imbobo ye-PON eyodwa ihambisana nesihlukanisi sokubona esisodwa.I-PON (Inethiwekhi ye-Passive Optical) inethiwekhi ye-passive Optical.Imbobo ye-PON ngokuvamile ibhekisela embobeni engezansi yomfula ye-OLT futhi ixhunywe kusihlukanisi esibonakalayo.Imbobo ekhuphukayo ye-ONU ingabuye ibizwe ngokuthi imbobo ye-PON.Imodemu yokubona isho imodemu ye-fiber optic, futhi zonke izinto zokusebenza zokuguqula ukuphela komsebenzisi ze-fiber optic zingabizwa ngokuhlangene ngokuthi imodemu yokubona.Ukushintshashintshashintshashintshashintshashintshashintshashintsha amasignali edijithali abe amasiginali e-analogi adluliswa emigqeni yocingo, futhi ukwehlisa ukuguqula amasignali e-analog abe amasignali edijithali, ngokuhlangene abizwa ngokuthi imodemu.Sisebenzisa izintambo zocingo ukuze sidlulise amasignali e-analog, kuyilapho ama-PC edlulisela amasignali edijithali.Ngakho-ke, lapho uxhuma ku-inthanethi ngocingo, kufanele usebenzise imodemu.
3. ONT (Optical Nerwork Unit)okokusebenza kwenethiwekhi ye-optical, okulingana ne-ONU.Kuyidivayisi yenethiwekhi yokubona esetshenziswa ekugcineni komsebenzisi.Umehluko uwukuthi: I-ONT iyitheminali yenethiwekhi yokubona, etholakala ngqo ekugcineni komsebenzisi, kuyilapho i-ONU iyiyunithi yenethiwekhi yokubona, futhi kungase kube namanye amanethiwekhi phakathi kwayo nomsebenzisi, njenge-Ethernet.Imikhiqizo ye-CeitaTech's ONU/ONT ingasetshenziswa njengemikhiqizo ye-ONU/ONT noma njengamarutha.Umkhiqizo owodwa unokusebenzisa okuningi.
4. I-OLT (itheminali yomugqa wokubona)optical line terminal, okokugcina okusetshenziselwa ukuxhuma imigqa ye-fiber optical trunk.Imisebenzi: (1) Thumela idatha ye-Ethernet ku-ONU (Optical Network Unit) ngendlela yokusakaza, (2) Qalisa futhi ulawule inqubo esukela futhi urekhode ulwazi olusukela, (3) Nikeza umkhawulokudonsa ku-ONU, okungukuthi, lawula ukuqala kokuthumela idatha ye-ONU.isikhathi sokuqala nokuthumela usayizi wewindi.Inethiwekhi exhunywe phakathi kwempahla yehhovisi emaphakathi (OLT) kanye nempahla yomsebenzisi (ONU/ONT) ngenethiwekhi yokusabalalisa optical (ODN) eyakhiwe amakhebuli okubona angenzi lutho kanye nezihlukanisi/izihlanganisi.
5. I-Opticali-fiber transceiveriyiyunithi yokuguqula imidiya yokudlulisa ye-Ethernet eshintshanisa amasignali kagesi amabili asontekile amabanga amade namasiginali okubona amabanga amade.Ibizwa nangokuthi i-photoelectric converter (I-Fiber Converter) ezindaweni eziningi..Umkhiqizo uvame ukusetshenziswa ezindaweni zangempela zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumboza futhi i-fiber optical kufanele isetshenziselwe ukunweba ibanga lokudlulisela, futhi ngokuvamile ubekwe endaweni yokusetshenziswa kwesendlalelo sokufinyelela samanethiwekhi endawo yedolobha elikhulu;isiza ukuxhuma imayela lokugcina lemigqa ye-fiber optic kumanethiwekhi endawo yedolobha elikhulu nakunethiwekhi yangaphandle.
