Ukuthunyelwa kwe-10G PON Technology:
Njengamanje, ukwakhiwa kwe-broadband ngokuyinhloko kuyi-FTTH, kodwa ukwakhiwa kwe-10G PON kusaphethwe yi-10G PON + LAN.Amadolobha afana ne-Beijing, i-Shanghai, i-Guangzhou ne-Shenzhen, lapho i-FTTH isetshenziswa kusenesikhathi, aseqalile ukubhekana nesidingo sokuthuthukiswa kwenethiwekhi yokuqala ye-FTTH.Kodwa-ke, ngenxa yezinhlobo ezincane kanye nentengo ephezulu yamatheminali ku-10G PON ONT, i-10G PON isetshenziswa kakhuluOLTside ngesikhathi esifushane, kuyilapho uhlangothi lwetheminali lusasebenzisa amatheminali e-EPON / GPON ukwandisa ukusekelwa kwamachweba e-GE, futhi lunikeze isevisi yasekhaya ye-gigabit ngenani elincane labasebenzisi.Ngokuzayo, ngokuthandwa kwabasebenzisi bomkhawulokudonsa ophezulu, kanye nesilinganiso samatheminali angu-10G PON kanye nokwehla kwentengo, ukusetshenziswa kwesikali se-10G PON FTTH kuzothuthukiswa kancane kancane.Njengamanje, ukuthunyelwa kwesikali se-10G EPON kuOLTuhlangothi selulungile, futhi ukuthunyelwa kwe-XG (S) -PON ngaphakathiOLTidinga ukuvuthwa nge-Combo PON.Ngenxa yemikhawulo yokusetshenziswa okujwayelekile kobuchwepheshe, izindleko ze-Combo PON ziphakeme ngempela kuno-10G EPON.Ukwengeza, yenza kube lula izinga le-XGPON, usebenzisa ubude begagasi obufanayo njenge-10G EPON ngaleyo ndlela ukususa i-WDM1r kunethiwekhi ye-ODN.Futhi kuyindlela engenzeka yokudela umkhawulokudonsa ukuze uphilisane ne-GPON ONT, kodwa idinga ukukhuthaza ukuguqulwa kwezinga le-XG-PON.
Izisetshenziswa zabakhiqizi ezingasekeli ikhadi lebhodi le-10G PON kunethiwekhi yamanje kufanele zishintshwe kancane kancane, futhi okokusebenza okungenhla kufanele kususwe kancane kancane ngokuthuthela komsebenzisi kwenye i-OLT kanye nokushintshwa kwemishini iyonke.
Izincomo ezihlobene nokusetshenziswa kobuchwepheshe:
Njengamanje, inethiwekhi ye-PON iphethe izinsizakalo ezahlukahlukene ezifana ne-broadband, izwi, ukusakazwa bukhoma kwe-IPTV, i-IPTV efunwayo kanye nolayini ozinikele.Ngesikhathi esifanayo, inethiwekhi ye-PON iphethe ulwazi lokuphathwa kwenethiwekhi yamadivayisi we-PON namasango asekhaya, futhi ingase iphathe ukubuyisela kweselula kanye nezinsizakalo zokungena ngaphambili esikhathini esizayo.Ngokukhula kwezinhlobo zamabhizinisi kanye nenani elincane labasebenzisi abangaphansi kwembobo ye-PON eyodwa (ngokuvamile ishumi ukuya kwengamashumi), ithrafikhi yembobo ye-PON eyodwa inezici zokungaqiniseki okunamandla okuzumayo nokukhulu.Indlela yasekuqaleni yokubala ithrafikhi ngokwemodeli yebhizinisi ayisajwayelaniswa nezici zethrafikhi zenethiwekhi ye-PON.Kuphakanyiswa ukuthi inethiwekhi ye-PON kufanele isebenzise amasu ezobuchwepheshe alandelayo ukuze kusetshenziswe ukwandisa umkhawulokudonsa wenethiwekhi futhi kuthuthukiswe ulwazi lomsebenzisi.
① Inethiwekhi yokufinyelela yesevisi ye-IPTV isetshenziswe ngokugcwele ngokusakaza kwesendlalelo sesi-2, ngeOLTkusetshenziswa i-IGMPProxy kanye ne-ONU zisebenzisa i-IGMP Snoop-ing ukuze kuncishiswe ukusebenza komkhawulokudonsa wembobo ye-PON.
② Inethiwekhi yokufinyelela ku-broadband isebenzisa ubuchwepheshe be-QoS obusekelwe ku-802.1p, obubeka kuqala ukuze kuqinisekiswe ukudluliselwa kwezinsizakalo eziza kuqala.
③ Isango lasekhaya kanye nebhokisi elibekwe phezulu linophenyo oluthambile olwakhelwe ngaphakathi, futhi lusebenzisana nesistimu yokuqapha ithrafikhi yenethiwekhi kanye nesistimu yokuhlaziya (njengeHuawei uTraffic, i-ZTE BigDNA, njll.) ukuze kuqashwe ukuqapha okunamandla ezingeni lebhizinisi kanye nezinga lenethiwekhi.
Izimbobo ze-PON ezingakakwazi ukuhlangabezana nezidingo zomkhawulokudonsa ngokusebenzisa amasu obuchwepheshe angenhla kufanele zilungiswe ngokulungisa ukusatshalaliswa komsebenzisi, kuncishiswe isilinganiso sokuhlukaniswa kokubona kanye nokuthuthukisa i-10G PON.
Okungenhla yiziphakamiso mayelana nokuthunyelwa kwenethiwekhi yobuchwepheshe be-10G PON kanyeOLTukuziphendukela kwemvelo okulethwa yi-Shenzhen HDV Phoelectron Technology Co., LTD.I-Shenzhen HDV Phoelectron Technology Co., LTD.inezingxenyekazi zekhompuyutha ezinamandla namandla esoftware, futhi imikhiqizo ephambili edayiswa kakhulu yile:
OLTimishini: i-olt yokubeka, i-olt encane, i-compact olt, i-olt switch, i-olt module, i-olt yokuxhumana, njll.
I-ONUokokusebenza: i-olt onu, i-ac onu, i-onu ehlakaniphile, i-onu yokuxhumana, i-onu yasekhaya,
