US cable operator Cox Communications has officially announced plans to launch a symmetrical 10G bandwidth service that will target different access network formats such as HFC, FTTP and wireless, for which the company says it will invest billions of dollars over the next few years to build a 10Gbps oriented fibre network. They have invested almost US$19 billion in network construction and service upgrades over the past decade, and will continue to upgrade their DOCSIS 4.0 and FTTP networks in the future. In the past, they have used the FTTP network to roll out 1Gbps services under the "Gigablast" programme.
It is estimated that the company currently has nearly 7 million residential and business customers. Not long ago they also participated in the first application for the Rural Digital Construction Fund RDOF, receiving approximately US$6.63 million in support. For this purpose a commitment was made to bring broadband internet to 8,212 rural locations in nine states.
US cable operators, represented by Cox, have traditionally been fans of DOCSIS technology for HFC networks, and Cox has indicated that it will deploy the latest generation of 4.0 DOCSIS technology. This technology supports 10Gbps downlink and up to 6G uplink, while claiming better security and latency performance. In contrast, some legacy HFC networks have started to embrace FTTP networks, such as Altice USA.
