Re: ftth is too expensive. Here, DOCSIS3 plans are up to 250mbps, so very easy to do 100mbps.
And the Comcast user who can't get 12/2 with a SB510x, DOCSIS3 will likely help you, it might not. The SB510x modems will only use one channel, a number of them on your node doing lots of traffic, will saturate the single channel, DOCSIS3, will use 2-8 channels, spreading the traffic out to different channels on compatible modems.
Single channel is ~38mbps, so if you have 3 modems trying to do 12/2, that will work, but there is not enough bandwidth to do 4 modems at full speed on DOCSIS2 on a node.
