E-China, i-100M ye-broadband ye-optical iye yathandwa, kwaye ixesha le-Gigabit liza kuvula. Kwi-2019, uMphathiswa wezoShishino kunye neTeknoloji yoLwazi uqalise "i-Double G Double Lifting, iNethiwekhi efanayo yeSpeed Speed" isenzo kwi-intanethi ye-broadband network, kwaye iqhubekile nokukhawulezisa ukukhuthazwa kwezicelo ze-broadband ezisisigxina ze-Gigabit. I-teknoloji ye-GPON ye-10G inokufikelela kwi-"khulu". megabytes" ukuya kwi "gigabit". I-teknoloji ye-10G ye-GPON ibhekisela kwiiteknoloji ezifana ne-XG-PON, i-XG-PON & ne-GPON Combo, i-XGS-PON, i-XGS-PON & ne-GPON Combo. Ukuziphendukela kwemvelo kwi-10G GPON kufuneka kuthathelwe ingqalelo imiba yokuhambelana kwezinto ezahlukeneyoIi-ONU.
Ukuze ukusombulula ingxaki XG-PON ayihambelani ne GPONI-ONU, I-ZTE ngowokuqala ukuphakamisa iteknoloji entsha ye-Combo PON ukuqaphela i-XG-PON & GPON Combo.Okwangoku, le teknoloji ye-Combo ye-PON ye-speed ezimbini iye yamkelwa ngabaqhubi ngenxa yokuhambelana kwayo kakuhle kunye nokulula. Kuye kwaba sisisombululo esisisiseko se-10G GPON yokwakha kwaye ifumaneka ngokurhweba kwinqanaba elikhulu.
Ngoku iteknoloji ye-XGS-PON ikhulile, kwaye i-XGS-PON inokubonelela nge-10G ye-bandwidth ephezulu kunye nezantsi, kodwa i-XGS-PONOLTinokuhambelana kuphela ne-XGS-PON kunye ne-XG-PON iindidi ezimbini zeI-ONU, ngelixa inani elikhulu leGPON kunyeI-ONUzibekwe kuthungelwano ekhoyo, kunye nokuhambelana network ekhoyo GPON kunyeI-ONUkufuneka isonjululwe xa uthungelwano luguqukela kwi-XGS-PON. Ukuze kusonjululwe le ngxaki, i-ZTE indulule itekhnoloji yeCombo yodidi oluthathu, eyile XGS-PON kunye neGPON ukuphumeza iCombo, exhasa uphuculo olugudileyo lweGPON ukuya kwiXGS-PON.
Umgaqo wetekhnoloji ye-Combo ye-PON enemigangatho emithathu
I-XGS-PON&GPON's Combo PON isisombululo sisisombululo esakhelwe ngaphakathi esixhasa i-XGS-PON/XG-PON/GPON yeendlela ezintathu zokuhlala. esona sisombululo sigudileyo sophuculo lweGPON ukuya kwi-XGS-PON.
I-Combo ye-Pon enemilinganiselo emithathu isebenzisa umgaqo we-wavelengths ehlukeneyo ye-carrier nge-XGS-PON kunye ne-GPON teknoloji, kwaye idibanisa i-wavelengths ezimbini kwimodyuli enye ye-optical ukuqonda ukuhanjiswa okuzimeleyo kunye nokwamkelwa kwe-GPON kunye ne-XGS-PON iimpawu ze-optical. Imodyuli ye-PON ye-optical inomdibanisi owakhelwe-ngaphakathi onokudibanisa phezulu naphantsi amaza amaza amane afunekayo ekwahlukaneni kwe-XGS-PON kunye ne-GPON.XGS-PON kunye ne-XG-PON zisebenzisa ubude be-wavelength efanayo, obuyi-wavelength enyukayo ye-1270 nm kunye nomlambo osezantsi. I-wavelength ye-1577 nm.GPON isebenzisa i-1310nm ukuphakama kwe-wavelength kunye ne-1490nm ezantsi kwe-wavelength, kwaye imodyuli ye-Combo ye-PON ye-optical yezinga lesithathu ibona i-fiber-four-wavelength transmission and processing (jonga uMfanekiso 1).
I-Combo ye-PON enemilinganiselo emithathu ibonelela ngekhono leetheminali ze-GPON ezihambelanayo. Ngenxa yobuchwephesha be-WDM, i-bandwidth ebonelelwa lizibuko le-PON sisimbuku se-bandwidth ye-XGS-PON kunye ne-GPON channels. I-terminal ye-GPON, i-downlink bandwidth enikezelwa yi-port nganye ye-PON yi-12.5 Gbps (10 Gbps + 2.5 Gbps), kunye ne-uplink bandwidth yi-11.25 Gbps (10 Gbps + 1.25 Gbps).
Isisombululo se-ZTE se-Combo se-PON esinenqanaba ezintathu
Ibhodi ye-ZTE ye-Combo ye-Pon enemigangatho emithathu ithatha i-8/16-port XGS-PON&GPON uyilo lwehardware yeetshaneli ezimbini. Enye i-Combo ye-PON port ihambelana nee-PON MAC ezimbini (GPON MAC kunye ne-XGS-PON MAC) kunye neendlela ezimbini zomzimba (i-WDM1r idibaniswe kwimodyuli ye-optical). Kwisalathiso se-downlink, amaza amabini e-downlink aqhutywe yi-PON MAC eyahlukileyo, ithunyelwe kwimodyuli ye-optical yokuphindaphinda, kwaye emva koko ithunyelwe kwiindawo ezahlukeneyo.Ii-ONU. I-XGS-PONI-ONUifumana uphawu lwe-XGS-PON, kunye ne-XG-PONI-ONUifumana iXG. – Umqondiso wePON, GPONI-ONUifumana isignali yeGPON.Kwindlela yokunyuka, iGPON kunye neXGS-PON zisebenzisa ubude bamaza ahlukeneyo, hluza kuqala kwimodyuli ye-optical, kwaye emva koko uqhubele phambili kwiitshaneli ezahlukeneyo ze-MAC.I-XGS-PON kunye ne-XG-PON zisebenzisa ubude obufanayo kwaye kufuneka zenze ukucwangciswa kwe-DBA. kwitshaneli enye.
Inombolo yezibuko yekhadi le-Combo PON yi-8 okanye i-16 izibuko. Inkangeleko kunye nojongano lomzimba yinto enye ukuya kwenye. Oku kuququzelela ulawulo lwemihla ngemihla kunye nokugcinwa kwesixhobo kunye nenkqubo yolawulo lwemithombo.Xa uqwalasela idatha yolawulo lwenethiwekhi, kufuneka udibanise uhlobo olutsha lwebhodi, kunye nenombolo yeGPON, XG-PON, kunye ne-XGS-PON.Ii-ONUukuchonga ngokuzenzekelayo iI-ONUthayipha kwaye ulungelelanise umjelo.Njengoko i-port ye-Combo ye-PON ene-speed ezintathu ihambelana namajelo amabini omzimba, iindlela zokulawula ukugcinwa zimi ngolu hlobo lulandelayo: I-Combo PON port ibandakanya iziteshi ezimbini zomzimba: GPON kunye ne-XGS-PON. Izibalo zokusebenza kunye nolawulo lwe-alamu kufuneka lwandiswe ngokusekelwe kwi-MIB yokuqala (iSiseko soLwazi loLawulo).
Ukufikelela ekuqaleni kolwazi ngokuzimeleyo kwi-GPON kunye ne-XG (S)-PON iziteshi, kuyimfuneko ukufumana ulwazi lweendlela ezimbini eziphathekayo ngexesha elifanayo.
Ii-MIBs ezinxulumene nolunye ulungelelwaniso lwenkonzo kunye nokusebenza kunye nolawulo lokugcinwa luhlala lungatshintshi. Ziqwalaselwe kwi-Combo PON port, kwaye i-Combo PON ilungelelanisa ngokuzenzekelayo kwisitishi.
Ukukhokela indlela yokwakhiwa kwe-PON ye-10G
Isantya esithathu seCombo PON inokufikelela kwi-XGS-PON, XG-PON kunye neGPON iintlobo ezintathu zeIi-ONUkwimfuno, enokuthi ikwazi ukuhlangabezana neemfuno zabaqhubi abahlukeneyo: I-XGS-PON ingasetyenziselwa urhulumente kunye nabasebenzisi bomgca weshishini labucala, kunye ne-XG-PON ingasetyenziselwa ukufikelela kwabasebenzisi beKhaya leGigabit, i-GPON isetyenziselwa ukufikelela kwababhalisi be-100M eziqhelekileyo.
Xa kuthelekiswa neskimu se-multiplexer sangaphandle, izibonelelo ze-Combo PON yamanqanaba amathathu ziyabonakala:
Akukho mfuneko yokulungelelanisa i-ODN, iprojekthi ilula. Xa i-multiplexer yangaphandle isetyenzisiweyo, kuyimfuneko ukunyusa i-multiplexer device, kwaye kuyimfuneko ukulungisa inethiwekhi ye-ODN kwinqanaba elikhulu, okunzima ukuyiphumeza kubunjineli, esinye sezizathu eziphambili zokuba kutheni i-XG-PON. kunzima ukukala.
Ilahleko entsha yokufakela ayiziswanga, kwaye ingxaki ye-optical power margin isonjululwe ngokupheleleyo. Ukusetyenziswa kwe-multiplexer yangaphandle kuya kwongeza ilahleko eyongezelelweyo ye-1 ~ 1.5db yokufakela, ngokungathandabuzekiyo imbi kakhulu kuhlahlo lwabiwo-mali lwamandla amaninzi asele eqinile, kwaye iprojekthi ayikwazi ukuphunyezwa.Inqanaba lesithathu le-Combo PON ayifaki ilahleko eyongezelelweyo yokufaka. . Xa inqanaba lemodyuli ye-optical efanayo yamkelwe, i-Combo PON iqaliswa, kwaye umda webhajethi yamandla optical yenethiwekhi ye-ODN ayitshintshi.
Gcina indawo kwigumbi lomatshini kwaye wenze lula ukusebenza kunye nokugcinwa.Imodyuli ye-Combo ye-PON ye-optical ye-speed ezintathu idibanisa imisebenzi efana ne-XG (S) -PON, GPON, kunye ne-WDM1r. Ayifaki izixhobo ezongezelelweyo kwaye ayithathi indawo eyongezelelweyo yegumbi, ukwenza lula ukugcinwa nokulawula.
I-OSS ilula ukukhwela, inkqubo yokuvula ayitshintshi, kwaye umgca ophezulu unqunyulwe.I-PON ye-Combo ene-speed ezintathu ithatha imodi ye-WDM. Itshaneli ye-XG(S)-PON kunye nejelo le-GPON zihambelana ngokuzenzekelayo neentlobo zazo zetheminali. I-XG (S) ekhoyo -PON kunye ne-GPON ixhunyiwe kwi-OSS, kwaye inkqubo yokuvula inkonzo ihlala ingatshintshi. Kulula ukuyivula, iprojekthi kulula ukuyisika.
Isisombululo se-Combo se-PON esinemigangatho emithathu sifumene ingqwalasela eninzi kubaqhubi abaqhelekileyo njenge-Orange, i-Telefonica kunye ne-China Mobile.Ngokusekelwe kwisisombululo se-Combo ye-PON kunye noshishino olukhulu lwezorhwebo, i-ZTE ithathe inxaxheba ngokunyanisekileyo kuvavanyo lwe-Combo PON yamanqanaba amathathu kwaye umsebenzi wezorhwebo wabaqhubi abaqhelekileyo, kwaye waqhubeka ekhokela i-10G GPON ukwakhiwa kwendlela yokwakha.
