Though other options, such as fiber-to-the-premise, are likely going to be a bigger part of the story, U.S. cable TV operators also believe they can upgrade their hybrid fiber coax networks for symmetrical 10 Gbps operation in a couple different ways, using either DOCSIS 4.0 or FTTH. Much will hinge on the incremental cost.
Many executives are going to prefer DOCSIS 4.0, assuming it continues to offer a lower capital investment profile than switching to full FTTH.
“We did the DOCSIS 3.1 rollout over two-year period which took our capability from a couple of 100 megabits per customer up to one gig per customer everywhere. capital cost of about $9 for home passed,” said Tom Rutledge, Charter Communications CEO.
