Just not seeing our market going in that direction yet.
This isn't just Huawei. I know at least Adtran can do GPON+XGS-PON in

I've been installing PON equipment for 2+ years where all the ports can be
fitted with optics (SFPs) that support both GPON and

I would argue that question 9 needs an option of "Both".
Secondly, two additional good questions to ask would be: are the ECN
values presently being treated as RFC3168?
Are the ECN values being modified by any AQM implementations (WRED,
FQ_CODEL, etc) on any switch or router in transit?

Due to the demand being predominately in the downward direction, half-duplex

channels to downstream, at the expense of upstream.

ONT always has SFP for PON. It is inside (built-in) – this way is cheaper. OK.
In this case, it is not SFP because it is not “pluggable”.
1G and 10G optics have a big cost difference for ONT.

CPE cost hurts in this case.
