Ngokwemibiko yabezindaba, uVerizon wanquma ukusebenzisa i-NG-PON2 esikhundleni se-XGS-PON ngokuthuthuka okulandelayo kwe-fiber okulandelayo. Ngenkathi lokhu kuphambana nokuthambekela kwezimboni, isigungu esiphezulu seVerizon sathi sizokwenza impilo ibe lula nge-verizon eminyakeni ezayo ngokwenza lula inethiwekhi kanye nokwenza ngcono indlela.
Yize i-XGS-PON ihlinzeka amandla we-10G, i-NG-PON2 inganikeza amahlandla amane we-wavelength ka-10g, engasetshenziswa yedwa noma ngokuhlanganiswa. Yize ama-opharetha amaningi akhetha ukuthuthukisa kusuka kuXgs-pon, IVerizon yabambisana ne-Equipment Surgebir Calix eminyakeni eminingana eyedlule yokufuna izixazululo ze-NG-PON2.
Kuyaqondakala ukuthi i-Verizon njengamanje isebenzisa i-NG-PON2 ukuthumela ama-Gigabit Fiber Fiber Services ezindaweni zokuhlala eNew York City. UVerizon kulindeleke ukuthi athumele ubuchwepheshe esikalini esikhulu eminyakeni embalwa ezayo, kusho uKevin Smith, i-Phrice Mongameli yezobuchwepheshe ye-Verizon's Fiber Optic Project.
NgokukaKevin Smith, i-Verizon yakhetha i-NG-PON2 ngezizathu eziningana. Okokuqala, ngoba inikeza amandla ama-wavelength amane ahlukene, inikeza "indlela nenhle ngempela yokuhlanganisa izinsizakalo zezohwebo nezokuhlala endaweni eyodwa" futhi zilawula uhla lwamaphoyinti ahlukile. Isibonelo, uhlelo olufanayo lwe-NG-PON2 lungasetshenziswa ukuhlinzeka ngezinsizakalo ze-2GBPS Optical Fibre kubasebenzisi bokuhlala, izinsizakalo ze-10GBPS Optical Fibre kubasebenzisi bebhizinisi, kanye nezinsizakalo ze-10g Frenthaul zifinyelela kumasayithi weselula.
UKevin Smith uphinde waveza ukuthi i-NG-PON2 ine-Integratedband Network Gateway (BNG) ehlanganisiwe yokuphathwa komsebenzisi. "Ivumela ukuhambisa enye yama-routers njengamanje asetshenziswe kunethiwekhi."
"Ngaleyo ndlela unendawo eyodwa encane yenethiwekhi ukuphatha," echaza. "Lokho kuza ngokwanda kwezindleko, futhi ngokujwayelekile kubiza kakhulu ukuqhubeka nokungeza umthamo wenethiwekhi ngokuhamba kwesikhathi. "
Ekhuluma ngokwengeziwe umthamo, uKevin Smith uthe ngenkathi i-NG-PON2 njengamanje ivumela ukusetshenziswa kwemigwaqo emine ye-10g, empeleni kukhona imizila eyisishiyagalombili esele izotholakala kubasebenzi ngokuhamba kwesikhathi. Ngenkathi izindinganiso zale mizila eyengeziwe sezisakhiwa, kungenzeka ukufaka izinketho ezifana nemizila emine engama-25g noma imizila emine.
Kunoma ikuphi, uKevin Smith ukholelwa ukuthi "kunengqondo" ukuthi uhlelo lwe-NG-PON2 luzogcina lube khona okungenani nge-100G. Ngakho-ke, yize kubiza kakhulu kune-XGS-PON, uKevin Smith uthe i-NGG-PON2 ikufanele.
Ezinye izinzuzo ze-NG-PON2 zifaka: Uma i-wavelength ukuthi umsebenzisi esebenzisa ngayo ehluleka, ingashintshelwa kwesinye isikhathi. Ngasikhathi sinye, futhi isekela ukuphathwa okuguquguqukayo kwabasebenzisi futhi ihlukanise abasebenzisi bakwa-High Bandwidth ngamagagasi abo ukugwema ukugcwala.
Njengamanje, verizon usanda kuqala ukuthunyelwa okukhulu kwe-NG-PON2 yama-Fios (insizakalo ye-fiber optic) futhi kulindeleke ukuthi uthenge imishini ye-NGO-PON2 ngezinga elikhulu eminyakeni embalwa ezayo eminyakeni embalwa ezayo. UKevin Smith uthe bekungekho izingqinamba zokuthengwa kwezidingo kuze kube manje.
"I-GONNS ibilokhu iyithuluzi elikhulu futhi i-gigabit ibingakaze ibe yilapho kudala ... kodwa ngobhubhane, abantu basheshise ukwamukelwa kwe-gigabit. Ngakho-ke, kithina, manje sekusondele isikhathi esinengqondo sesinyathelo esilandelayo, "uphetha.
