Yes, I’ve seen Comcast claim to offer 2G symmetric services in their
applications for funding from state/local authorities to expand their networks
to unserved or underserved areas. I have no reason to disbelieve this claim.
I’ve been talking to vendors about what’s going on for the next generation of
FTTx/PON and it looks quite attractive at this point, I’m excited to see the
latency drops and speeds go up for people once they’re off DSL or DOCSIS over
time.
In my early days of research for my “hobby ISP” as I call it, I looked at
getting older docsis systems as an option/alternative, and it seemed to be
worthwhile as without a TV overlay, there were more options for speed.
The reality is today once you have the infrastructure in place, if you planned
well you can easily upgrade with overlays.
