Malinga ndi malipoti a atolankhani, Verizon adaganiza zogwiritsa ntchito NG-PON2 m'malo mwa XGS-PON pakusintha kwa fiber ya optical m'badwo wotsatira. Ngakhale izi zikutsutsana ndi zomwe zikuchitika m'makampani, mkulu wa Verizon adati zipangitsa moyo wa Verizon kukhala wosavuta m'zaka zikubwerazi pochepetsa maukonde ndi njira yosinthira.
Ngakhale XGS-PON imapereka mphamvu ya 10G, NG-PON2 imatha kupereka mphamvu ya 10G nthawi zinayi kuposa nthawi ya 4, yomwe ingagwiritsidwe ntchito yokha kapena kuphatikiza. Ngakhale kuti ogwiritsa ntchito ambiri amasankha kukweza kuchokera ku GPON kupita kuXGS-PON, Verizon adagwirizana ndi kampani yogulitsa zida Calix zaka zingapo zapitazo kuti apeze mayankho a NG-PON2.
Zikumveka kuti Verizon pakadali pano ikugwiritsa ntchito NG-PON2 popereka chithandizo cha gigabit fiber optic m'nyumba zogona ku New York City. Verizon ikuyembekezeka kugwiritsa ntchito ukadaulowu pamlingo waukulu m'zaka zingapo zikubwerazi, anatero Kevin Smith, wachiwiri kwa purezidenti wa ukadaulo wa projekiti ya Verizon fiber optic.
Malinga ndi Kevin Smith, Verizon yasankha NG-PON2 pazifukwa zingapo. Choyamba, chifukwa imapereka mphamvu ya mafunde anayi osiyanasiyana, imapereka "njira yokongola kwambiri yophatikizira ntchito zamalonda ndi zapakhomo papulatifomu imodzi" ndipo imayang'anira malo osiyanasiyana ofunikira. Mwachitsanzo, njira yomweyo ya NG-PON2 ingagwiritsidwe ntchito popereka ntchito za ulusi wa 2Gbps kwa ogwiritsa ntchito okhala m'nyumba, ntchito za ulusi wa 10Gbps kwa ogwiritsa ntchito mabizinesi, komanso ntchito za 10G fronthaul kumasamba am'manja.
Kevin Smith adanenanso kuti NG-PON2 ili ndi ntchito yolumikizirana ya broadband network gateway (BNG) yoyang'anira ogwiritsa ntchito. "Imalola kusuntha imodzi mwa ma rauta omwe akugwiritsidwa ntchito mu GPON kuchokera pa netiweki."
“Mwanjira imeneyi mumakhala ndi gawo limodzi lochepa la netiweki yoti muyendetse,” iye anafotokoza. “Izi zimabwera ndi kukwera kwa mtengo, ndipo nthawi zambiri zimakhala zotsika mtengo kupitiriza kuwonjezera mphamvu ya netiweki pakapita nthawi.”
Ponena za kuchuluka kwa mphamvu, Kevin Smith adati ngakhale kuti NG-PON2 pakadali pano imalola kugwiritsa ntchito njira zinayi za 10G, pali njira zisanu ndi zitatu zomwe zidzaperekedwa kwa ogwiritsa ntchito pakapita nthawi. Ngakhale miyezo ya njira zowonjezerazi ikupangidwabe, ndizotheka kuphatikiza njira monga njira zinayi za 25G kapena njira zinayi za 50G.
Mulimonsemo, Kevin Smith akukhulupirira kuti "ndizomveka" kuti makina a NG-PON2 pamapeto pake athe kukulitsidwa kufika pa 100G. Chifukwa chake, ngakhale kuti ndi okwera mtengo kuposa XGS-PON, Kevin Smith adati NG-PON2 ndiyofunika.
Ubwino wina wa NG-PON2 ndi monga: Ngati kutalika kwa mafunde komwe wogwiritsa ntchito akugwiritsa ntchito kwalephera, kumatha kusinthidwa yokha kukhala kutalika kwina kwa mafunde. Nthawi yomweyo, imathandiziranso kasamalidwe kamphamvu ka ogwiritsa ntchito ndipo imalekanitsa ogwiritsa ntchito mafunde amphamvu pa kutalika kwa mafunde awoawo kuti apewe kudzazana.
Pakadali pano, Verizon yangoyamba kumene kugwiritsa ntchito NG-PON2 pa FiOS (Fiber Optic Service) ndipo ikuyembekezeka kugula zida za NG-PON2 pamlingo waukulu m'zaka zingapo zikubwerazi. Kevin Smith adati pakadali pano palibe vuto lililonse lokhudza kugulitsa zinthu.
"GPON yakhala chida chabwino kwambiri ndipo gigabit sinakhalepo kwa nthawi yayitali ... koma ndi mliriwu, anthu akufulumizitsa kugwiritsa ntchito gigabit. Chifukwa chake, kwa ife, tsopano ndi nthawi yokwanira yopezera sitepe yotsatira," akumaliza.
