Of course I don't know the setup in this particular case but from what I've heard, gfiber is mostly GPON with 1:16 splits. They have used different ONT versions but the "current" generation seems to be a custom ONT from an ODM: https://support.google.com/fiber/answer/6035992?hl=en&ref_topic=2667450 https://wikidevi.com/wiki/Google_Fiber_Jack_v2_(GFLT110) Also, this may be interesting: https://gfiber-review.googlesource.com/#/c/1232/ --001a114012e013e444053f9f4a3b Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

What's the setup here? Someone has told me that Google Fiber is PON? So= there is an ONT at the customer prem which takes fiber and hands off some = kind of 1GBASE-T? What more?

Just trying to figure out what device has ~13-15 megabyte buffer so it can = induce 1200ms buffer lag at 1 gigabit/s.

Of= course I don't know the setup in this particular case but from what I&= #39;ve heard, gfiber is mostly GPON with 1:16 splits. They have used differ= ent ONT versions but the "current" generation seems to be a custo= m ONT from an ODM:
