Yeah, that's what I figured. There are lots of older PON deployments that used the modulated RF approach.
From what I have read, Verizon's FIOS does that. RFoG cable TV for certain frequencies, normal ethernet data for other frequencies, and dedicated bandwidth for VoIP.
Cable companies in Canada have begun to deploy FTTH in greenfields. And those are deployed to be compatible with their coax infrastructure. The fibre from the CMTS is simply extended to the home instead of stopping at a "node" on a telephone pole. The coax starts at the ONT to get to the TV sets. Not sure if they have a DOCSIS modem attached to the coax or if they get the ethernet out of ONT. However, Rogers seems to have areas being deployed differently and I *believe* it is pure ethernet. (and not even sure if GPON). Rogers also wants to go all IPTV , something unexpected from a traditional cableTV company. Something to consider about dark fibre L1 service: If city lets Service Providers perform installations (string from telephone pole to homes etc), you need to worry about damages they can cause. And in cases when customer unsubscribes from SP-1 and subscribes to SP-2 you have to make sure that SP-1 doesn't damage the termination of the fibre in the home to make installation by SP-2 harder/costlier. In an L2 service, the city is responsible for all installations and de-installs and has no incentive to damage the infrastructure to hurt a competitor. And generally, the CPE is installed by city and stays in place when end user swiches service provider.
