1. AP, irutha engenazingcingo,ihambisa imiqondiso yenethiwekhi ngeeperi ezijijekileyo. Ngokuqulunqa i-AP, iguqula imiqondiso yombane ibe yimiqondiso yerediyo ize iyithumele ngaphandle.
2. I-ONU (Iyunithi yeNethiwekhi yokubona)iyunithi yenethiwekhi yamehlo. Izixhobo zenethiwekhi ye-PON, i-PON isebenzisa i-fiber optical enye ukuxhuma kwi-OLT, kwaye ke i-OLT ixhunyiwe kwi-ONU. I-ONU inikezela ngedatha, IPTV (Interactive Internet Television), ilizwi kunye nezinye iinkonzo. Izibuko lePON apha libhekisa kwizibuko kwi OLT. Enye izibuko yePON ihambelana nesahluli sokubona esinye. I-PON (iNethiwekhi ye-Passive Optical) inethiwekhi ye-passive yamehlo. Izibuko lePON libhekisa jikelele kwizibuko elisezantsi le OLT kwaye lidityaniswe kwisahlukanisi samehlo. Izibuko eliphezulu le ONU linokubizwa ngokuba lizibuko lePON. Imodem ye-Optical ibhekisa kwimodem yefiber optic, kwaye zonke izixhobo zokuguqula i-fiber optic ekupheleni komsebenzisi zinokubizwa ngokudibeneyo njengemodem yokubona. Ukumodareyitha kukuguqula imiqondiso yedijithali ibe ziimpawu ze-analog ezithunyelwa kwimigca yefowuni, kwaye ukuthotywa kwe-analog kukuguqula imiqondiso ye-analog kwimiqondiso yedijithali, ngokudibeneyo ebizwa ngokuba yimodem. Sisebenzisa imigca yefowuni ukuhambisa iimpawu ze-analog, ngelixa ii-PC zihambisa iimpawu zedijithali. Ke ngoko, xa uqhagamshela kwi-Intanethi ngocingo lwefowuni, kufuneka usebenzise imodem.
3. I-ONT (iYunithi yeNerwork yokukhanya)izixhobo zenethiwekhi zamehlo, ezilingana ne-ONU. Sisixhobo senethiwekhi ye-optical esetyenziswa ekupheleni komsebenzisi. Umahluko kukuba: I-ONT yi-terminal ye-optical network, ebekwe ngokuthe ngqo ekupheleni komsebenzisi, ngelixa i-ONU iyiyunithi yenethiwekhi ye-optical, kwaye kunokubakho ezinye iinethiwekhi phakathi kwayo kunye nomsebenzisi, njenge-Ethernet. Iimveliso ze-CeitaTech ze-ONU/ONT zingasetyenziswa njengemveliso ye-ONU/ONT okanye njengee-routers. Imveliso enye inosetyenziso oluninzi.
4. OLT (itheminali yomgca wokubona)i-terminal ye-optical line, izixhobo ze-terminal ezisetyenziselwa ukudibanisa imigca ye-fiber optical trunk. Imisebenzi: (1) Thumela idatha ye-Ethernet kwi-ONU (i-Optical Network Unit) ngendlela yosasazo, (2) Qalisa kwaye ulawule inkqubo yoluhlu kwaye urekhode ulwazi olusuka, (3) Yabela i-bandwidth kwi-ONU, oko kukuthi, ukulawula ukuqala kwe ONU ukuthumela idatha. ixesha lokuqala kunye nokuthumela ubungakanani befestile. Uthungelwano oluqhagamshelwe phakathi kwezixhobo zeofisi ephakathi (OLT) kunye nesixhobo somsebenzisi (ONU/ONT) ngokusebenzisa inethiwekhi yokusabalalisa i-optical (ODN) ehlanganiswe neentambo ze-passive optical kunye ne-optical splitters / combiners.
5. I-Opticali-fiber transceiveryiyunithi yokuguqula imidiya yosasazo ye-Ethernet etshintshiselana umgama omfutshane ojijekileyo wemiqondiso yombane kunye nemiqondiso yokubona ekude. Ikwabizwa ngokuba sisiguquli sombane (Isiguquli seFayibha) kwiindawo ezininzi. . Imveliso isetyenziswa ngokubanzi kwiindawo ezichanekileyo zothungelwano apho iintambo ze-Ethernet azikwazi ukugubungela kwaye i-fiber optical kufuneka isetyenziswe ukwandisa umgama wothumelo, kwaye ngokuqhelekileyo ibekwe kwi-access layer application ye-broadband network network networks; inceda ukudibanisa imayile yokugqibela yemigca yefiber optic kuthungelwano lwengingqi yemetropolitan kunye nakwinethiwekhi yangaphandle.
