Comcast has surpassed 100,000 rPHY digital nodes deployed across its nationwide network. The rollout began in 2019, surpassing 50,000 rPHY nodes deployed across the network in 2022. The pace continued to increase in 2023, with the organization upgrading 25 percent of its footprint to date.
Comcast said the node upgrades are part of its broader DAA and virtualization journey, which has included world’s first activation of a virtualized cable modem termination system (vCMTS) powered by Full Duplex DOCSIS 4.0 technology in 2021. Since then, Comcast has implemented vCMTS technology across its network and continues to improve the platform to deliver even greater capacity, reliability, visibility, and security.
“But what’s more exciting about our continued commitment to deploying network innovation, as evidenced by the digital nodes across our network, is the immediate benefits it delivers to our Xfinity 10G Network customers with respect to speed, reliability, sustainability and scalability,” said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable.
