Built by Broadcom, the device is expected to become the world’s first production silicon to be developed using the DOCSIS 4.0 Full Duplex standard, which represents an evolutionary leap forward in the ability to deliver ultra-fast speeds over HFC networks. One of the most important breakthroughs in the DOCSIS 4.0 standard is the ability to use network spectrum more efficiently, allowing operators to dramatically increase upstream speeds without sacrificing downstream spectrum to do so.
“We are always pushing the envelope to stay ahead of our customers’ growing needs,” said
A key advantage of DOCSIS 4.0 Full Duplex is that it establishes a foundation for operators to deliver multigigabit speeds over their existing networks to the connections already in hundreds of millions of homes around the world, without the need for massive digging and construction projects. With this technology, Comcast can continue to deliver ultra-fast service today while simultaneously building capacity for consumers’ potential future needs.

“With this test we gain a powerful new tool to support our mission of delivering the best possible connected experiences to our customers,” Nafshi said.
The Full Duplex DOCSIS test is the latest milestone on Comcast’s path to 10G. Last October, Comcast technologists were able to deliver 1.25 Gig symmetrical speeds over a live, all-digital network by leveraging advances in Distributed Access Architecture, Remote PHY digital nodes, and a cloud-based virtualized cable modem termination system platform (vCMTS). Even as Comcast works to test and deploy Full Duplex DOCSIS to enable multigigabit upload and download speeds in the future, the company is leveraging the technologies from the October trial, along with DOCSIS 3.1 in the upstream, to increase speed and capacity in the near term.
10G is a global industry initiative to stay ahead of consumer demand by developing and deploying new network technology to dramatically increase upload and download capacity in the coming years.
