Cable One prepares network for DOCSIS 4.0 as it contemplates the future of 10G


Cable One is laying the groundwork for DOCSIS 4.0, making a series of network upgrades that it hopes will ease its eventual deployment of the technology and ultimately its path to 10 Gbps.

The operator said it is currently working to update its network return path to allow symmetrical multi-gig service and reclaim the spectrum used for traditional linear video services. It is also improving the capacity of its hybrid fiber coaxial plant to 1.8 GHz.

“Gig speed is just the beginning of the story,” said Julie Laulis, CEO of Cable One. and ensure that we continue to stay well ahead of the consumer consumption curve. “

Cable One already delivers gigabit speeds to residential customers over 99% of its footprint. However, Laulis said the move to “10G will transform the customer experience, creating new possibilities for smart cities, connected homes, virtual and augmented reality and businesses.”

The operator did not say for sure which of the two versions of DOCSIS 4.0 – full duplex (FDX) or Frequency Division Duplex (FDD, also known as extended spectrum or ESD) – it is suing. However, the changes it makes to plant capacity seem consistent with an FDD / ESD approach.

Several other major operators have started to expand their DOCSIS 4.0 plans in recent months.

Comcast, for example, recently said it was ramping up the pace of DOCSIS 4.0 work and focused on mid-split upgrades as a stepping stone to full duplex. Cox Communications, meanwhile, already has mid-split implementations in place and plans to move to a high-split setup in the near future.

Elsewhere, Canadian operator Shaw Communications has said it is preparing for a switch to FDD / ESD DOCSIS 4.0 by 2030, with deployments scheduled to begin in 2024.
