No, and there's good reason why, I'm about to write a response to Owen
that will also expand on why.
There are a number of issues with the muni running the ONT:
- Muni now has to have a different level of techs and truck rolls.
- The Muni MMR now is much more complex, requiring power (including
backup generators, etc) and likely 24x7 staff as a result.
- The muni-ont will limit users to the technologies the ONT supports.
If you want to spin up 96x10GE WDM your 1G ONT won't allow it.
- The optic cost is not significantly different if the muni buys them
and provides lit L2, or if the service/provider user provides them.
The muni should sell L1 patches to anyone in the MMR. Note, this
_includes_ two on-net buildings. So if your work and home are connected
to the same muni-MMR you could order a patch from one to the other.
It may now be max ~20km, so you'll need longer reach optics, but if you
want to stand up 96x10GE WDM you're good to go.
