Comcast expects to have an FDX Amplifier prototype in its labs by July. If the product works as advertised, it will vastly broaden Comcasts ability to roll out Full Duplex DOCSIS on its HFC networks.

At the CableLabs 10G Showcase, Charter and Comcast showed progress in the form of DOCSIS 4.0 demos powered by a blend of commercially-ready products and prototype technologies.

With early lab trials, a first wave of interoperability testing and collaborations between key suppliers, DOCSIS 4.0 made significant progress in 2021, even as deployments remain well out on the horizon.

The rise of this new class of product will put Comcast in position to deploy upstream-boosting Full Duplex DOCSIS technology to a large portion of its HFC network.

Cable op claims another 10G milestone with Full Duplex DOCSIS (FDX) live lab trial that linked its virtual cable modem termination system to DOCSIS cable modems configured to operate in the FDX spectrum band.

Suppliers are making rapid process with network and CPE elements that will support the Extended Spectrum DOCSIS flavor of DOCSIS 4.0, Coxs Jeff Finkelstein says.

Integration is a big near-term focus, but Comcasts virtual CMTS now speaks DOCSIS 4.0, and the MSO is also pushing ahead with deployments of a distributed access architecture, says Comcasts Rob Howald.
