Ngokweengxelo zeendaba, iVerizon igqibe ekubeni isebenzise i-NG-PON2 endaweni ye-XGS-PON kwisizukulwana esilandelayo sokuphucula i-optical fiber. Nangona oku kuchasene neendlela zoshishino, umphathi weVerizon uthe kuya kwenza ubomi bube lula kwiVerizon kwiminyaka ezayo ngokwenza lula inethiwekhi kunye nendlela yokuphucula.
Nangona i-XGS-PON inika amandla e-10G, i-NG-PON2 inokubonelela ngobude be-10G obuphindwe kane, obunokusetyenziswa bodwa okanye ngokudibeneyo. Nangona uninzi lwabaqhubi lukhetha ukuphucula ukusuka kwi-GPON ukuya kwi-I-XGS-PON, I-Verizon isebenzisane nomthengisi wezixhobo uCalix kwiminyaka embalwa eyadlulayo ukufuna izisombululo ze-NG-PON2.
Kuyaqondakala ukuba iVerizon okwangoku isebenzisa i-NG-PON2 ukusasaza iinkonzo ze-gigabit fiber optic kwiindawo zokuhlala eNew York City. IVerizon kulindeleke ukuba isasaze obu buchwepheshe ngomlinganiselo omkhulu kwiminyaka embalwa ezayo, utshilo uKevin Smith, usekela-mongameli wezobuchwepheshe kwiprojekthi ye-fiber optic yeVerizon.
Ngokutsho kukaKevin Smith, iVerizon ikhethe i-NG-PON2 ngezizathu ezahlukeneyo. Okokuqala, kuba inika amandla obubanzi bee-wavelengths ezine ezahlukeneyo, inika "indlela entle kakhulu yokudibanisa iinkonzo zorhwebo kunye neendawo zokuhlala kwiqonga elinye" kwaye ilawula uluhlu lweendawo ezahlukeneyo zemfuno. Umzekelo, inkqubo efanayo ye-NG-PON2 ingasetyenziselwa ukubonelela ngeenkonzo ze-2Gbps optical fiber kubasebenzisi beendawo zokuhlala, iinkonzo ze-10Gbps optical fiber kubasebenzisi bezoshishino, kwaneenkonzo ze-10G fronthaul kwiindawo zeselula.
UKevin Smith ukwathe ukuba i-NG-PON2 inomsebenzi we-integrated broadband network gateway (BNG) wolawulo lwabasebenzisi. “Ivumela ukuhambisa enye yee-routers ezisetyenziswa kwi-GPON ngoku ngaphandle kwenethiwekhi.”
“Ngaloo ndlela unenqaku elinye elingaphantsi kwenethiwekhi ekufuneka ulilawule,” ucacisile. “Ewe oko kuza nokunyuka kweendleko, kwaye ngokubanzi kubiza kancinci ukuqhubeka nokongeza amandla enethiwekhi ngokuhamba kwexesha.”
Ethetha ngomthamo owandisiweyo, uKevin Smith uthe nangona i-NG-PON2 okwangoku ivumela ukusetyenziswa kweendlela ezine ze-10G, kukho iindlela ezisibhozo zizonke eziya kuthi ekugqibeleni zifumaneke kubaqhubi ngokuhamba kwexesha. Nangona imigangatho yale mizila eyongezelelweyo isaphuhliswa, kunokwenzeka ukubandakanya iindlela ezifana neendlela ezine ze-25G okanye iindlela ezine ze-50G.
Nokuba kunjalo, uKevin Smith ukholelwa ukuba “kusengqiqweni” ukuba inkqubo ye-NG-PON2 ekugqibeleni ikwazi ukwandiswa ibe yi-100G ubuncinane. Ke ngoko, nangona ibiza kakhulu kune-XGS-PON, uKevin Smith uthe i-NG-PON2 ifanelekile.
Ezinye iingenelo ze-NG-PON2 ziquka: Ukuba ubude be-wavelength obusetyenziswa ngumsebenzisi buyasilela, bunokutshintshelwa ngokuzenzekelayo kwenye ubude be-wavelength. Kwangaxeshanye, ikwaxhasa ulawulo oluguquguqukayo lwabasebenzisi kwaye ihlukanisa abasebenzisi abane-bandwidth ephezulu kwii-wavelength zabo ukuze baphephe ukuxinana.
Okwangoku, iVerizon isandula ukuqalisa ukusasazwa kwe-NG-PON2 ngobuninzi kwiFiOS (iFiber Optic Service) kwaye kulindeleke ukuba ithenge izixhobo ze-NG-PON2 ngobuninzi kwiminyaka embalwa ezayo. UKevin Smith uthe akukho ngxaki zobonelelo okwangoku.
“I-GPON ibisisixhobo esihle kakhulu kwaye i-gigabit ibingekho ixesha elide… kodwa ngenxa yobhubhane, abantu bayakhawulezisa ukwamkelwa kwe-gigabit. Ngoko ke, kuthi, ngoku lixesha elifanelekileyo lokufikelela kwinqanaba elilandelayo,” uqukumbela.
