WDM-PON, giving each customer their own lambda of bandwidt= h. Effectively a 1:1 split.

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'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:


Also, this may be interesting:
