Inethiwekhi yokufinyelela yamehlo (okungukuthi, inethiwekhi yokufinyelela enokukhanya njengendlela yokudlulisela, esikhundleni sezintambo zethusi, isetshenziselwa ukufinyelela umndeni ngamunye. Inethiwekhi yokufinyelela yokubona).Inethiwekhi yokufinyelela ebonakalayo ngokuvamile iqukethe izingxenye ezintathu: itheminali yomugqa wokubukaOLT, iyunithi yenethiwekhi yokubonaI-ONU, inethiwekhi yokusabalalisa ebonakalayoI-ODN,laphoOLT futhiI-ONUizingxenye eziyinhloko zenethiwekhi yokufinyelela okubonakalayo
OLTimele i-Optical Line Terminal.OLTi-optical line terminal, iyimishini yehhovisi lezokuxhumana, esetshenziselwa ukuxhuma isiqu se-fiber optical, indima ilinganashintshaor umzilakunethiwekhi yezokuxhumana yendabuko, iyithuluzi lokungena kwenethiwekhi yangaphandle kanye nokungena kwenethiwekhi yangaphakathi. Ibekwe ekugcineni kwendawo, imisebenzi yokuphatha ebaluleke kakhulu ukuhlela ithrafikhi, ukulawulwa kwebhafa, kanye nokuhlinzeka ngesixhumi esibonakalayo senethiwekhi yefayibha ebheke umsebenzisi kanye nokwaba umkhawulokudonsa. Kalula nje, kuwukufeza imisebenzi emibili, enhla nomfula, ukuqedela ukufinyelela phezulu komfula wenethiwekhi ye-PON; Phansi komfula, idatha etholiwe ithunyelwa kubo bonkeI-ONUamadivaysi okugcina abasebenzisi ngokusebenzisa inethiwekhi ye-ODN.
I-ONUIyunithi ye-Optical Network.I-ONUinemisebenzi emibili: ukuthola ngokukhetha ukusakaza okuthunyelwaOLT, kanye nokwamukela impendulo ku-OLTuma idatha idinga ukwamukelwa; Qoqa futhi ufake kunqolobane idatha ye-Ethernet umsebenzisi adinga ukuyithumela, bese uthumela idatha egcinwe kunqolobaneOLTi-terminal ngokuya ngewindi lokuthumela elabelwe.
Kunethiwekhi ye-FTTx (chofoza lapha Ukuze ufunde ngokushesha nge-FTTx), iI-ONUimodi yokufinyelela iyahlukahluka ngokusetshenziswa okuhlukile. Isibonelo, i-Fiber To The Curb (FTTC): TheI-ONUibekwe ekamelweni lemishini emaphakathi yeseli. I-FTTB(I-Fiber Iya Esakhiweni):I-ONUibekwe ebhokisini lokugcina lephaseji; I-FTTH(Ifayibha Eya Ekhaya): II-ONUibekwe kumsebenzisi wasekhaya.
OLTiyitheminali yokuphatha,I-ONUiyitheminali; Ukuvulwa kwenkonzo yeI-ONUilethwa ngeOLT, futhi ubuhlobo phakathi kwalaba ababili buyinkosi nesigqila. OkuningiAma-ONUingaxhunywa ku-OLTngokusebenzisa isihlukanisi.
I-ODN iyi-Optical Distribution Network, inethiwekhi yokusabalalisa optical, umzila obonakalayo wokudlulisela optical phakathiOLTfuthiI-ONU. Umsebenzi wayo oyinhloko ukuqedela ukudluliswa kwe-bidirectional yamasignali optical. Ivamise ukwakhiwa nge-fiber optical nekhebula, isixhumi esibonakalayo, isihlukanisi se-optical, kanye nezinto ezisizayo zokufaka nokuxhuma lawa madivayisi. Enye yezingxenye ezibaluleke kakhulu i-optical splitter.
I-HDVinganikeza amakhasimende uhla olugcwele lwemikhiqizo ye-FTTH nezisombululo. Isungulwe ngo-2012, i-HDV ingumhlinzeki wesixazululo esitobhini esisodwa kanye nomkhiqizi we-ODM & OEM wamanethiwekhi okufinyelela efayibha. Ngokwezidingo zamakhasimende, singakwazi ukusiza amakhasimende ukuthi aklame izikimu zokuklama imikhiqizo engabizi kakhulu kanye nemikhiqizo eyenziwe ngokwezifiso, futhi sinikeze iziqinisekiso zekhwalithi ze-ODM nezinsizakalo ze-OEM. Bekulokhu kubambelela emoyeni wobumbano, ukusebenza kanzima, ukusungula izinto ezintsha, ukusebenza kahle kanye nobuqotho, enekhono eliqinile le-R & D lobuchwepheshe nohlelo oluphelele lokulethwa, ukuhlinzeka amakhasimende ngemikhiqizo yemishini yokuxhumana ye-fiber ephezulu yekhwalithi ephezulu kanye nezixazululo zobuchwepheshe, masisebenze ndawonye, win-win ikusasa!
