I agree that DOCSIS is an efficient method of data transport for multiple access systems but is not suited to point to point fibre links.

Further, DOCSIS requires heavy FEC because of the coaxial element of the network that digital transport over fibre does not.

I'd suggest that the best topology would be 10Gb capable digital fibre links to the existing street cabs. These would contain the DOCSIS CMTS equipment feeding a small group of end users over the existing final drop coax.

You're right; the coaxial final drop is the issue; its the cable system's trump card.
