Showoff. :-)

I hope I said "E7"; it's what I meant to say. Yes, I wasn't going to
stop at Calix; I'm just juggling budgetary type numbers at the moment;
I'll have 3 or 4 quotes before I go to press. It's a 36 month project
just to beginning of build, at this point, likely.
Assuming I get the gig at all.

Other people here, said it. If nothing else, it's certainly what the
largest nationwide FTTH provider is provisioning, and I suspect it serves
more passings than anything else; possibly than everything else.
But it doesn't matter either way, except in cross-connects between my MDF
and my colo cages; except for GPONs apparent compatibility with RF CATV
delivery (which I gather, but have not researched) is just block-upconvert,
I don't care either way; there's no difference in the plant buildout.
