There is a significant number of broadband Internet services around the world that still implement cable-modem technology that uses the coaxial cable rather than Ethernet or xDSL technology for the copper run.
But most of these setups are limited to an asymmetrical download-upload bandwidth even though newer DOCSIS 3.0 standards open up download speeds of 1Gbps. This has effectively ruled out cable-modem services for business applications including those of us who work from home.
CableLabs have cemented a new standard called Full Duplex DOCSIS 3.1 which allows for symmetrical bandwidths of up to 10Gbps. This can allow cable-TV companies and the like who implement coaxial-cable technology to sell business-grade cable-modem Internet using that technology. The idea will be to bake it in to the DOCSIS 3.1 specification suite which will be used to assess cable-modem endpoint equipment and cable-Internet services.
I would also see this benefit fibre-coaxial next-generation broadband setups by allowing for up to 10Gbps symmetrically and making them legitimate with a wide range of users. The main problem that will affect its deployment in the US cable marketplace is the notorious reticence for the cable companies to implement this technology or make it available for a price that is reasonable for residential and small-business users. This is a symptom of the poor level of competition that is existing in that marketplace.
