Re: Comcasts refusal to push for FTTP/FTTH why?

RFoG to nodes would be there to support the existing network while fiber is being run.

Like I said, this is what legacy HFC already is, more or less. It doesn't change anything.

BTW are you still in Santa Cruz? What ever happened to Santa Cruz fiber announced in 2015?

I guess it’s probably arguing semantics here. It would probably be left alone unless they had to make a change to support it for some reason.

A big IF they ever do EPON I guess it will probably happen on a different wavelength over the existing HFC fiber.

As for Santa Cruz fiber mostly MIA. City funding fell through and they barely have any capital to build out.

They’ve been heavily pushing wireless solutions and marketing as fiber backed…

EPON has its wavelengths set by the spec so I'm not sure what you even mean.

EPON from an RPHY node puts the OLT in the node.

You just answered your original question. ($$$)

I mean different wavelengths from the HFC stuff. Pretty much running EPON and HFC over the long fiber runs back to the headend or whatever. Perhaps there’s already a provision for this.

RPHY puts the EPON OLT in the node, not in the headed. No need to worry about sharing the fiber between HFC and EPON.

Your right actually. This is kind of the entire idea of RPHY. They don’t want our RF going to and from the headend. All the RF is going to be on the R-PHY node.

I guess everything going back to the headend will just be Ethernet?

Yes

That certainly sounds much simpler architecture wise.

I suppose cheap off-the-shelf single mode 10G SFP+ Ethernet modules would work for a connection to the R-PHY node?

If so it sounds like you could cover A very large area in a single rack at the headend vs what’s going on now.

Yes. See videomatics pic above. That solves a major issue of available headend space, power, and HVAC capacity.

EPON from an RPHY node puts the OLT in the node.

And Remote OLT puts the Optic in the DAA. Cannot wait to see that rolled out in mass for green fields someday.
