This paper provides an overview of the Cox hybrid fiber-coax (HFC) network and its transformation towards delivering the 10G vision. The network roadmap maps different customer service tiers to HFC configurations, such as the sub-split, mid-split, high-split, and ultra-high split 1.8GHz configurations. The goal of achieving 10G is enabled by DOCSIS® 4.0 (D4.0), 1.8 GHz plant, ultra-high split, All-IP video migration, and other network component upgrades. The All-IP migration program and customer premise equipment align with this network transformation, with a recommendation to implement the premise architecture as All-IP and single-outlet. This long-range plan aims to achieve the All-IP 10G Network via DOCSIS 4.0, providing multi-gig services with 10G capacity across much of the HFC network.
