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.

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.
