Considering that GPON isn't a new thing and is rather widely deployed
(At least in Europe)
it would be awesome for FOSS products to exist but I have yet to see
any progress made towards
it despite the specification itself being public, but the
drivers/blobs that actually interact with (mostly Realtek)
GPON SoC-s are currently black boxes.

I am unaware of any project working towards FOSS GPON or XGPON(Or any
new 10G variants).

Robert
