Google最新發布影片內的設備來看,可以確定是使用Point-to-point架構,每戶使用頻寬100%獨享1G/1G直達機房
目前中華電信只有專業型以上等級才會用點對點供裝,Google Fiber是家用就給你
所以不要拿中華電信所謂的6個月1G試點來跟Google Fiber比,完全沒有可比性
8用戶去分1G/1G沒問題,問題是單一用戶就能夠把1G/1G吃滿才是問題,這根本不是可實際供裝的方式
作作秀可以
中華電信1G/1G竟敢開價3500?樣樣比不上,只有價格遠遠超越
註:Google Fiber不是使用PON,每戶都是獨立1G/1G,這才是NGN該使用的,PON是共享的,例:EPON是所有使用者共享1G/1G*,GPON是所有使用者共享2.5G/1.25G

On this occasion, one of its leaders explains how each household connected individually to the Google Fiber Huts, which unlike GPON networks such as Telefonica can offer 1 Gbps symmetrical.
John Toccalino, project manager, explains that being installed in various parts of the city a few huts or nodes called Google Fiber Huts. Inside house the OLT equipment that connect the pairs of fiber, which then hung from utility poles, reach every home. For its explanation, we understand that Google is not using a GPON network like the one in Spain is installing Telefónica.
With this architecture, the network of Google not only provides 1 Gbps to each user, but this is symmetrical, which would be impossible in a GPON deployment, having to share all the users upload rate up to 1, 25 Gbps

The benefit of this model is simple: every home that has Google Fiber service will have their very own fiber-optic cable that directly connects all the way back to the Internet backbone.
*GPON Does not Require 8b/10b Ethernet Encoding Requirement of EPON.
GPON = 20% More Efficient than EPON in Carrying IP Traffic
EPON 1.25G/1.25G實際上只能跑1G/1G(EPON只有80%效率)

專用設備我也搞不清楚, 不過我猜應該是修改的 Gigabit Ethernet transceiver , 等於 L2 直連.
說實在的, Google 這套已經是目前全世界最奢華的網路了, 跟中華電信.. 呃, 基本上沒有可比性.
802.11N 3T3R 450M WiFi,中華電信的ONU就隨便找個盒子把電路板包起來而已,不要挑戰宅宅工程師的審美觀
法國free ONU
背面,有光纖接入口,但似乎用不到,實際供裝只當無線分享器使用

Google在全球都有網路,與各大ISP都有互連(hinet剛剛好例外),連外品質>>>>>>>hinet
hinet連youtube可是吃連美頻寬.....昨天Google Fiber發表會直播就會頓了,更別提直播720P(不開中研院連台灣Google,而且這是PPPoE固定IP的表現,如果是浮動IP....),直播慢取可是一點屁用都沒有
中華電信100M/100M+72小時斷線+單檔上傳鎖30M+非固定制下載鎖死97M(Line Rate)(註)+沒有PPPoE固定IP連外品質顯著下降+YouTube頓的要死=NT$1699
註:2013/1/11 中華電信數據分公司(HiNet)修正之後已是100M Line Rate
中華電信4M/1M=NT$799
