CableLabs, the industry consortium responsible for world-wide cable interoperability specifications, has performed rigorous testing on Broadcom-powered modems and residential gateways against its specifications to ensure full compatibility between DOCSIS modem and cable infrastructure products.

The DOCSIS 3.1 specification allows cable operators to efficiently deliver increased broadband speeds without changes to the existing cable plant. The latest DOCSIS specification also covers world-wide deployments, unlike the previous specification that had separate DOCSIS and EuroDOCSIS certifications. The certified products include upstream splits for both North America and Europe including 204 MHz and 85 MHz. With the certification of OEM products, Broadcom's BCM3390 system-on-a-chip (SoC) meets this specification to increase network efficiency by up to 50 percent, enabling new content and services over hybrid fiber-coaxial (HFC) networks with in-home data speeds of 1 Gbps and more.

"The speed with which the DOCSIS 3.1 specification and certification has been completed underscores the competitive landscape of offering Gigabit-speed services to residential subscribers," said Dan Marotta, Broadcom Executive Vice President and General Manager, Broadband & Connectivity Group. "Broadcom was first to lead the market with hardware for cable operators to expand their broadband services, and is now the first DOCSIS 3.1 silicon to receive CableLabs' certification as well."

"DOCSIS 3.1 technology is vital for Comcast. Earlier this year we installed the world's first DOCSIS 3.1 modem on a customer-facing network and before the end of 2016 we will begin offering DOCSIS 3.1-powered gigabit service to customers in several parts of the country," said Tony Werner, Executive Vice President and Chief Technology Officer at Comcast. "I applaud Broadcom for its progress on certification process, which helps to create a clear path for technology that will enhance our customers' online experiences."

"Our customers expect us to stay ahead of the curve in providing the latest broadband services and content," said Balan Nair, Liberty Global Executive Vice President and CTO. "Broadcom's smooth passage through the DOCSIS 3.1 certification process helps the cable industry continue on this journey as we all look to new ways in which we can deliver our customers an even better experience."
