1. AP, irutha engenazingcingo,ithumela 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 ngokubanzi kwizibuko elisezantsi le OLT kwaye lidityaniswe kwisahlukanisi samehlo.Izibuko elinyukayo le ONU lingabizwa 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 yimiqondiso ye-analog ethunyelwa kwimigca yefowuni, kwaye ukuthotywa kukuguqula imiqondiso ye-analog ibe yimiqondiso 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. ONT (iYunithi yoMsebenzi we-Optical Nerwork)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 iyunithi 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.
