There's a cable operator I know of who is using RFoG. There's
apparently an RFoG ONU they install in/on the house, and then they use
the same cable modems and STB's they use with their coax service.
I imagine it would only make sense if you're wanting to re-use an
existing cable head end, but I haven't looked into it deeply.

It would make it even easier for me when people come over from Hughes
Net. Right now I just use their coax as a cable pull.

Like i said, it was a stupid idea. I'm all on board the fiber train,
but having had some rodent just eat through the fiber cable going to
the top (on the tower side of the service loop), I was longing for
something that I could just patch back together.

If we're changing methods, we should be going to glass and power up

Subject: [AFMUG] A Stupid coax question
Comcast has been deploying their WIFI hotspot network like mad in
the
Chicago metro. Every public park, gas station, strip mall, hotel,
and
train station seems to have a wifi AP hung outside of it now. These
units just hang on their aerial coax cable, and get their power and
data
just off a single RG-6 coax run off the nearest splitter. Drawing
the
power off the DC Coax plant. Here's a picture of a typical
installation.

So this got me thinking again, as I have for several years, why are
we
still using POE to run PMP Equipment on towers. It seems from a
installation, RF Shielding, and grounding/suppression perspective,
using
coax would be the far better choice. Anyone can be taught to
terminate
a perfect RG6 in <5 minutes. No Colors to remember. Any couplers
are
inherently waterproof. No loose plugs or broken clips. Cheap cheap
cheap outdoor cable. Shielded cables by default. It just seems
that
there are a lot of benefits for the low power draw radios.
Obviously a
licensed link can't pull enough power over an RG6, but EPMP or 450
or
UBNT PMP radios I would think could run just fine. Instead of
having to
deal with switching equipment or breakout boxes at the top of a
tower,
just run up a larger coax to a splitter. No outdoor enclosure
needed.
Is it simply a lack of products that would make development costs
too
much, or is there another technical aspect I'm missing. Docsis
version
3.1 Full Duplex, which is currently in development will do 10gb
sync,
Docsis 3.1 is 10gb/1gb. More than enough for any of our AP Clusters
for
at least a few years.
https://en.wikipedia.org/wiki/DOCSIS#Comparison
<https://en.wikipedia.org/wiki/DOCSIS#Comparison>
It seems like UBNT or Cambium (heck Motorola already had all the
coax
products built) could easily make a 10gb Fiber to Coax adapter for
the
tower base. Feed it with Fiber and DC, then just keep adding
splitters
and radios until you run out of power budget.
It just seems like I've never heard it discussed, and I'm not sure
why.
Obviously there is something I'm missing. Docsis is a standard, but
maybe there's no standard for the power delivery on the coax? So
vendor
Inter-op prohibits development dollars from being spent on it.
