E-China, i-100M optical broadband isidumile, futhi inkathi ye-Gigabit isizovuleka.Ngo-2019, uMnyango Wezimboni Nobuchwepheshe Bolwazi wethula isenzo se-"Double G Double Lifting, Same Network Same Speed" kumanethiwekhi e-broadband, futhi waqhubeka nokusheshisa ukukhuthazwa kwezicelo ze-gigabit egxilile ye-broadband. Ubuchwepheshe be-GPON be-10G bungafinyelela ukweqa kusukela "ekhulwini megabytes" kuya "gigabit".Ubuchwepheshe be-10G GPON bubhekisela kubuchwepheshe obufana ne-XG-PON, XG-PON & GPON Combo, XGS-PON, XGS-PON & GPON Combo.Ukuvela kwe-10G GPON kudinga ukucabangela izindaba zokuhambisana kwama-ONU ahlukahlukene.
Ukuze kuxazululwe inkinga yokuthi i-XG-PON ayihambisani ne-GPON ONU, i-ZTE ingeyokuqala ukuphakamisa ubuchwepheshe obusha be-Combo PON ukuze kubonakale i-XG-PON & GPON Combo.Okwamanje, lobu buchwepheshe be-Combo PON obunamagiya amabili sebuyisiwe. yamukelwe ngabaqhubi ngenxa yokuhambisana kwayo okuhle nokuba lula.Sekuyisixazululo esijwayelekile sokwakhiwa kwe-10G GPON futhi itholakala ngokuthengisa ngezinga elikhulu.
Manje ubuchwepheshe be-XGS-PON sebuvuthiwe, futhi i-XGS-PON inganikeza i-10G yomkhawulokudonsa olinganayo okhuphuka nomfula ophansi, kodwa i-XGS-PON OLT ingahambisana kuphela ne-XGS-PON ne-XG-PON izinhlobo ezimbili ze-ONU, kuyilapho inani elikhulu le-GPON futhi i-ONU isetshenziswe kunethiwekhi ekhona, futhi ukuhambisana kwenethiwekhi ekhona ye-GPON ne-ONU kufanele ixazululwe lapho inethiwekhi iguqukela ku-XGS-PON. kanye ne-GPON ukusebenzisa i-Combo, esekela ukuthuthukiswa okushelelayo kwe-GPON kuya ku-XGS-PON.
Isimiso sobuchwepheshe se-Combo PON enezilinganiso ezintathu
Isixazululo se-XGS-PON&GPON's Combo PON yisixazululo esakhelwe ngaphakathi se-multiplexer esisekela i-XGS-PON/XG-PON/GPON yezindlela ezintathu zokuphilisana. Isixazululo esingcono kakhulu sokuthuthukiswa okushelelayo kwe-GPON kuya ku-XGS-PON.
I-Combo PON enezilinganiso ezintathu isebenzisa umgomo wamaza obude obuhlukile benkampani yenethiwekhi ngobuchwepheshe be-XGS-PON kanye ne-GPON, futhi ihlanganisa ubude begagasi obubili kumojula eyodwa yokubona ukuze ibone ukudluliswa okuzimele kanye nokucutshungulwa kokwamukela kwe-GPON kanye ne-XGS-PON amasignali optical.I-Combo enesivinini ezintathu. Imojula ye-PON optical inesihlanganisi esakhelwe ngaphakathi esingahlanganisa ukuphakama naphansi kwamaza amane adingekayo ukuze kuhlukaniswe i-XGS-PON kanye ne-GPON.XGS-PON kanye ne-XG-PON zisebenzisa ubude begagasi obufanayo, obuwubude obuphezulu bomfula obungu-1270 nm kanye nomfula ongezansi. I-wavelength ye-1577 nm.GPON isebenzisa i-1310nm ubude be-wavelength obukhuphukayo kanye ne-1490nm yezansi yomfula ongezansi, futhi imojula ye-Combo PON optical yezinga ezintathu ibona ukudluliswa nokucutshungulwa kwe-fiber-four-wavelength (bona Umfanekiso 1).
I-Combo PON enezilinganiso ezintathu inikeza amandla amatheminali e-GPON ahambisanayo.Ngenxa yobuchwepheshe be-WDM, umkhawulokudonsa ohlinzekwa yimbobo ye-PON uyisamba somkhawulokudonsa weziteshi ze-XGS-PON kanye ne-GPON.Lapho imbobo ye-Combo PON enezilinganiso ezintathu ixhunywe kanyekanye kutheminali ye-XG(S)-PON kanye I-GPON terminal, i-downlink bandwidth ehlinzekwa yimbobo ngayinye ye-PON ingu-12.5 Gbps (10 Gbps + 2.5 Gbps), kanti i-uplink bandwidth ingu-11.25 Gbps (10 Gbps + 1.25 Gbps).
Isixazululo se-ZTE se-Combo PON esinezilinganiso ezintathu
Ibhodi le-Combo PON lezilinganiso ezintathu le-ZTE lamukela idizayini yezingxenyekazi zekhompuyutha eziyi-8/16-port XGS-PON&GPON.Imbobo eyodwa ye-Combo PON ihambisana nama-PON MAC amabili (GPON MAC ne-XGS-PON MAC) kanye namashaneli amabili angokwenyama (i-WDM1r ihlanganiswe kumojula yokubona).Esiqondisweni se-downlink, amaza amabili e-downlink acutshungulwa yi-PON MAC ehlukile, athunyelwe kumojula yokubona ukuze aphindaphindeke, bese ethunyelwa kuma-ONU ahlukene.I-XGS-PON ONU ithola isignali ye-XGS-PON, bese i-XG-PON ONU ithola i-XG.- Isignali ye-PON, i-GPON ONU ithola isignali ye-GPON.Esiqondisweni esikhuphukayo, i-GPON ne-XGS-PON zisebenzisa ubude begagasi obuhlukene, zihlunge kuqala kumojula ye-optical, bese zicutshungulwa eziteshini ezahlukene ze-MAC.I-XGS-PON ne-XG-PON zisebenzisa ubude be-wavelength efanayo futhi udinga ukwenza ukuhlela kwe-DBA esiteshini esifanayo.
Inombolo yembobo yekhadi le-Combo PON izimbobo eziyi-8 noma eziyi-16.Ukubukeka nokubonakalayo ngokomzimba kukodwa-kuya-komunye.Lokhu kusiza ukuphathwa nokugcinwa kwansuku zonke kwedivayisi kanye nesistimu yokuphatha izinsiza.Lapho ulungisa idatha yokuphatha inethiwekhi, udinga ukwengeza uhlobo olusha lwebhodi, bese ufaka izinombolo ze-GPON, XG-PON, kanye ne-XGS-PON ONU ukuze uhlonze ngokuzenzakalelayo Uhlobo lwe-ONU futhi uvumelanise isiteshi.Njengoba imbobo ye-Combo PON enamajubane amathathu ihambisana namashaneli amabili aphathekayo, izindlela zokuphatha zokulungisa zimi kanje: Imbobo ye-Combo PON ihlanganisa amashaneli aphathekayo amabili: i-GPON ne-XGS-PON.Izibalo zokusebenza nokuphathwa kwe-alamu kumele kunwetshwe ngokusekelwe ku-MIB yasekuqaleni (Isisekelo Solwazi Lokuphatha).
Ekuqaleni ukufinyelela ulwazi ngokuzimela kumashaneli e-GPON kanye ne-XG(S)-PON, kuyadingeka ukuthola ulwazi lwamashaneli amabili aphathekayo ngesikhathi esisodwa.
Ama-MIB ahlobene nokunye ukucushwa kwesevisi nokusebenza nokuphathwa kokulungiswa kuhlala kungashintshile.Alungiselelwe embobeni ye-Combo PON, futhi i-Combo PON ijwayela ngokuzenzakalelayo esiteshini.
Ihamba phambili kumkhuba wokwakhiwa kwe-10G PON
I-Combo PON enamasivinini amathathu ingakwazi ukufinyelela i-XGS-PON, i-XG-PON ne-GPON izinhlobo ezintathu zama-ONU uma kudingeka, ezingahlangabezana kalula nezidingo zama-opharetha abahlukene: I-XGS-PON ingasetshenziselwa abasebenzisi bolayini abazimele bakahulumeni kanye nebhizinisi, kanye ne-XG -I-PON ingasetshenziselwa ukufinyelela kwabasebenzisi be-Home Gigabit, i-GPON isetshenziselwa ukufinyelela okujwayelekile kwababhalisile abangu-100M.
Uma kuqhathaniswa nohlelo lwangaphandle lwe-multiplexer, izinzuzo ze-Combo PON enezilinganiso ezintathu zisobala:
Asikho isidingo sokulungisa i-ODN, iphrojekthi ilula.Uma i-multiplexer yangaphandle isetshenziswa, kuyadingeka ukwandisa idivayisi ye-multiplexer, futhi kuyadingeka ukulungisa inethiwekhi ye-ODN ngezinga elikhulu, okunzima ukulisebenzisa kwezobunjiniyela, okungesinye sezizathu eziyinhloko zokuthi kungani i-XG-PON okunzima ukukala.
Ukulahlekelwa okusha kokufaka akwethulwa, futhi inkinga yemajini yamandla okukhanya ixazululwa ngokuphelele.Ukusetshenziswa kwe-multiplexer yangaphandle kuzokwengeza ukulahleka kokufakwa okwengeziwe okungu-1~1.5db, okungangabazeki ukuthi kubi kakhulu kumabhajethi amaningi wamandla okubona asevele aqinile, futhi iphrojekthi ayikwazi ukuqaliswa.I-Combo PON enezilinganiso ezintathu ayifaki ukulahlekelwa kokufakwa okwengeziwe. .Lapho kwamukelwa izinga elifanayo lemojula ye-optical, i-Combo PON yethulwa, futhi umkhawulo wesabelomali samandla okukhanya wenethiwekhi ye-ODN awushintshi.
Yonga isikhala egumbini lomshini futhi wenze kube lula ukusebenza nokunakekela.Imoduli ye-Combo PON enamajubane amathathu ihlanganisa imisebenzi efana ne-XG(S)-PON, GPON, ne-WDM1r.Ayifaki imishini eyengeziwe futhi ayithathi indawo eyengeziwe yegumbi, yenza ukunakekelwa nokuphatha kube lula.
I-OSS kulula ukudokha, inqubo yokuvula ayishintshile, futhi umugqa ongenhla uyasikwa.I-Combo PON enamajubane amathathu isebenzisa imodi ye-WDM.Ishaneli ye-XG(S)-PON kanye nesiteshi se-GPON zifaniswa ngokuzenzakalela nezinhlobo zazo zetheminali.I-XG(S)-PON ne-GPON ekhona ixhunywe ku-OSS, futhi inqubo yokuvula isevisi ihlala ingashintshile.Kulula ukuyivula, iphrojekthi kulula ukuyisika.
Isixazululo se-Combo PON esinezilinganiso ezintathu sithole ukunakwa okuningi kubaqhubi abajwayelekile abafana ne-Orange, i-Telefonica ne-China Mobile.Ngokusekelwe kusixazululo se-Combo PON kanye nomkhuba omkhulu wezohwebo, i-ZTE ibambe iqhaza ngenkuthalo ekuhlolweni kwe-Combo PON yamazinga amathathu futhi umkhuba wokuhweba wabaqhubi abajwayelekile, futhi waqhubeka nokuhola umkhuba wokwakha we-10G GPON.
