(1) Umzila wokuthuthukiswa kwe-PON Technology we-10G
I-EPON ebuswa yi-IEEE, kanye ne-GPON ephethwe yi-ITU zombili ziguqukela kusiteji se-GPON eyi-10 okwamanje futhi ukuhlela okulandelayo kokubili okungu-100G PON. Kunomehluko othile emizileni ethile yokuziphendukela kwemvelo, futhi umzila wokuziphendukela kwemvelo ohambisanayo uboniswa esithombeni esilandelayo:
(2) Ukuziphendukela kwezobuchwepheshe kwe-EPON
Izindinganiso zobuchwepheshe nemikhiqizo ye-10G EPON ye-symmetric ne-asymmetric yenziwe yaphelela, Ngaphezu kwalokho, inenzuzo yokuhlalisana netheminali ye-EPON kunethiwekhi efanayo ye-ODN ngaphandle kokwengeza i-multiplexer. Ngemuva kokuthengwa kwezindawo ezimaphakathi kweOLTngo-2016, amamojula we-OLT we-10G PON ehlisiwe ngentengo
. Ngokucabangela ukuvela kwenethiwekhi kwesikhathi esizayo, opharetha baqala ukuthuthukisa i-10G EPON kusengaphambili ekugcineni kwendawo, futhi basasebenzisa i-EPON ONT kuklayenti ukuze benze ukwakhiwa kwe-FTTH. Ngesikhathi esifanayo, ngenxa yokuthi umehluko wentengo phakathi kwe-symmetric optical module kanye ne-asymmetric optical module awumkhulu, futhi uma kucatshangelwa isilinganiso somkhawulokudonsa we-asymmetric 10G EPON isixhumanisi esikhuphuka nomfula singu-1:10, ukuze kugwenywe isidingo sokuthuthukisa esibangelwa okulandelayo. ukuthuthukiswa kwesevisi ye-uplink, opharetha bathambekele kakhulu ekuthumeleni imodi ye-symmetric ye-10G EPONOLTohlangothini. Isinyathelo esilandelayo se-EPON sizoguqukela kubuchwepheshe be-100G PON.
(3) Ukuziphendukela kwezobuchwepheshe kwe-GPON
Ngokwezinga le-10G GPON, izinga lobuchwepheshe le-XG-PON elingalingani nemikhiqizo yenziwe yaphelela. I-wavelength engaguquki ye-symmetric 10G GPON standard XGS-PON ikhishwe ngoFebruwari 2016. Ngenxa yamadivayisi akhulile ahilelekile esilinganisweni, eminye imikhiqizo yabakhiqizi ilungele ukusetshenziswa kwezohwebo. Izinga le-NGPON2 (TWDMPON) elinobude begagasi obulungisekayo senziwe laphelele. Okwamanje,OLTimikhiqizo ibitholakala ngokwezentengiselwano e-Europe naseMelika.Ngasikhathi sinye, kunemikhiqizo ehambisanayo ye-MDU yemakethe yomugqa ozinikele webhizinisi. Imojula ye-optical ene-wavelength eguquguqukayo ye-NGPON2 iyabiza futhi kunzima ukuyifinyelela.Ngemva kokuba i-ITU igcwalise i-symmetrical fixed wavelength 10G standard (XGS-PON), abanye abakhiqizi bakholelwa ukuthi i-NGPON2 ingase yeqiwe futhi iguquke ngokuqondile kusixazululo se-PON ye-4 * 25G 100G, futhi kungenzeka ukuhlanganisa nezinga le-100G EPON.
Esikhathini esifushane, intengo ye-ONT ye-10G PON ngeke iwele ebangeni lentengo elikhona le-EPON / GPON, ngakho-ke akunakugwemeka ukubhekana nesimo sokuhlala ndawonye kwe-GPON engu-10 kanye nohlangothi lomsebenzisi i-EPON / GPON terminal. Ngenxa yokuthi amatheminali e-GPON kanye ne-XGPON ahlala ndawonye kunethiwekhi efanayo ye-ODN, amamojula e-WDM1r adinga ukungezwa, okukhawulela ukusetshenziswa kwe-XG-PON kunethiwekhi yamanje. Ngakho-ke, abakhiqizi abanenzuzo banohlelo lwe-Combo PON lwe-encapsulate GPON ne-XGPON amamojula optical kanye ne-WDM1r kumojula eyodwa ye-optical. Kodwa-ke, imojula yokubona yohlelo lwe-Combo PON ingapakishwa kuphela yi-XFP, futhi ibhodi elilodwa lingabona kuphela amachweba we-PON ayi-8 (okuvamile.I-SFP+ ukupakishwa, futhi ibhodi elilodwa lingathola amachweba we-PON ayi-16). Phakathi naleso sikhathi, ngenxa yokwanda kokulahlekelwa kokufakwa kwe-WDM1r, izidingo zamandla akhanyayo zamamojula optical ziphakeme. Njengamanje, amandla akhanyayo we-B +/N1 angabonakala kuphela, futhi imodyuli yamandla aphezulu we-C +/N2a ayikwazi ukunikezwa esikhathini esifushane, esikhawulela ukusetshenziswa kwezimo ezikude ze-spectral ratio.
Okungenhla incazelo ye-EPON nokuziphendukela kwezobuchwepheshe. Imikhiqizo yenethiwekhi ye-Shenzhen HDV photoelectron Technology Co., Ltd. yonke imishini ekhiqizwa kunethiwekhi ye-PON, kuhlanganisaI-ONUuchungechunge /OLTuchungechunge / optical module uchungechunge / transceiver uchungechunge nokunye. Ukuze wakhe okokusebenza kwenethiwekhi okuhle kakhulu, inkampani yethu ifakwe iqembu locwaningo nentuthuko, ukuze inikeze amakhasimende izinsizakalo zokwesekwa kwezobuchwepheshe ezisezingeni eliphezulu, wamukelekile ukufuna abasebenzi ukuze baqonde imikhiqizo yethu.
