Ngokusho kwemibiko yabezindaba, iVerizon inqume ukusebenzisa i-NG-PON2 esikhundleni se-XGS-PON ukuze kuthuthukiswe i-optical fiber yesizukulwane esilandelayo. Nakuba lokhu kuphambene nemikhuba yemboni, umphathi weVerizon uthe kuzokwenza impilo ibe lula kuVerizon eminyakeni ezayo ngokwenza lula inethiwekhi kanye nendlela yokuthuthukisa.
Nakuba i-XGS-PON inikeza amandla e-10G, i-NG-PON2 inganikeza ubude besikhathi obuphindwe kane kune-10G, obungasetshenziswa bodwa noma buhlanganiswe. Nakuba iningi labaqhubi likhetha ukuthuthukisa kusuka ku-GPON kuya ku-I-XGS-PON, iVerizon ibambisene nomhlinzeki wemishini uCalix eminyakeni eminingana edlule ukufuna izixazululo ze-NG-PON2.
Kuyaqondakala ukuthi iVerizon okwamanje isebenzisa i-NG-PON2 ukufaka izinsizakalo ze-gigabit fiber optic ezindaweni zokuhlala eNew York City. IVerizon kulindeleke ukuthi isebenzise ubuchwepheshe ngezinga elikhulu eminyakeni embalwa ezayo, kusho uKevin Smith, iphini likamongameli wezobuchwepheshe wephrojekthi ye-fiber optic yeVerizon.
Ngokusho kukaKevin Smith, iVerizon ikhethe i-NG-PON2 ngezizathu eziningana. Okokuqala, ngoba inikeza amandla amaza amane ahlukene, inikeza "indlela enhle kakhulu yokuhlanganisa izinsizakalo zezentengiselwano nezindawo zokuhlala epulatifomu eyodwa" futhi iphatha amaphuzu ahlukahlukene okufunwa. Isibonelo, uhlelo olufanayo lwe-NG-PON2 lungasetshenziswa ukuhlinzeka ngezinsizakalo ze-2Gbps optical fiber kubasebenzisi bezindawo zokuhlala, izinsizakalo ze-10Gbps optical fiber kubasebenzisi bebhizinisi, kanye nezinsizakalo ze-10G fronthaul kumasayithi eselula.
UKevin Smith uphinde waveza ukuthi i-NG-PON2 inomsebenzi we-integrated broadband network gateway (BNG) wokuphathwa kwabasebenzisi. “Ivumela ukuhambisa enye yama-router asetshenziswa njengamanje ku-GPON ngaphandle kwenethiwekhi.”
“Ngaleyo ndlela unephuzu elilodwa elincane lenethiwekhi okufanele uliphathe,” echaza. “Lokho kuhambisana nokwenyuka kwezindleko, futhi ngokuvamile kushibhile ukuqhubeka nokwengeza umthamo wenethiwekhi ngokuhamba kwesikhathi.”
Ekhuluma ngokwanda komthamo, uKevin Smith uthe yize i-NG-PON2 okwamanje ivumela ukusetshenziswa kwemizila emine ye-10G, empeleni kunemizila eyisishiyagalombili iyonke ezogcina itholakale kubasebenzi ngokuhamba kwesikhathi. Nakuba amazinga ale mizila eyengeziwe esathuthukiswa, kungenzeka ukufaka izinketho ezifana nemizila emine ye-25G noma imizila emine ye-50G.
Kunoma ikuphi, uKevin Smith ukholelwa ukuthi “kunengqondo” ukuthi uhlelo lwe-NG-PON2 luzogcina lukwazi ukukhuliswa lube okungenani yi-100G. Ngakho-ke, nakuba lubiza kakhulu kune-XGS-PON, uKevin Smith uthe i-NG-PON2 iyakufanelekela.
Ezinye izinzuzo ze-NG-PON2 zifaka: Uma ubude be-wavelength obusetshenziswa ngumsebenzisi buhluleka, bungashintshwa ngokuzenzakalelayo bube obunye ubude be-wavelength. Ngesikhathi esifanayo, isekela nokuphathwa okunamandla kwabasebenzisi futhi ihlukanisa abasebenzisi abane-bandwidth ephezulu kuma-wavelength abo ukuze kugwenywe ukuminyana.
Njengamanje, iVerizon isanda kuqala ukuthunyelwa kwe-NG-PON2 ngezinga elikhulu kwi-FiOS (Fiber Optic Service) futhi kulindeleke ukuthi ithenge imishini ye-NG-PON2 ngezinga elikhulu eminyakeni embalwa ezayo. UKevin Smith uthe bekungakaze kube nezinkinga zokuthengwa kwempahla kuze kube manje.
“I-GPON ibilokhu iyithuluzi elihle kakhulu futhi i-gigabit ibingasekho isikhathi eside… kodwa njengoba ubhubhane luqhubeka, abantu basheshisa ukwamukelwa kwe-gigabit. Ngakho-ke, kithi, manje sekuyisikhathi sokufinyelela. Isikhathi esinengqondo sesinyathelo esilandelayo,” uphetha.
