A DOCSIS 3.1 cable modem SoC, claimed to be the world’s first, has been introduced by Broadcom. The BCM3390 enables cable operators to deliver data to homes at speeds faster than 1Gb/s. Compared to existing spectrum allocations, the cable modem SoC delivers video content with a nearly 50% increased efficiency, and allows for the delivery and use of a new range of content and services.

The BCM3390 supports high-speed data rates exceeding 1Gb/s. A path for cable operators to transition to all-IP video is provided by the BCM93390 modem reference design, which offers up to 2Gb speeds in the home.

The DOCSIS 3.1 specification, which was designed to support the new era in Gigabit data and improve the spectral efficiencies of the available spectrum, enables higher-order modulations in existing hybrid fibre-coaxial networks without changes to the existing cable plant. The combination of low-density parity check-based forward error correction and orthogonal frequency division multiplexing technology in DOCSIS 3.1 allow operators to more efficiently install more data in the existing spectrum.

"Broadcom has engineered a breakthrough technology for operators to exceed Gigabit speeds on existing cable networks while simultaneously improving operational efficiencies," said Dan Marotta, Executive Vice President and General Manager, Broadband & Connectivity Group, Broadcom. "With our cable modem SoC, service providers can immediately begin to unlock the value of DOCSIS 3.1 to provide their subscribers with the best home networking experiences."

"The next-gen DOCSIS technology supports the Gigabit speeds our subscribers will increasingly demand over time," said Balan Nair, Executive Vice President and CTO, Liberty Global. "DOCSIS 3.1 will enable Liberty Global to deliver an even richer experience once we begin deploying this cost-effective technology during the second half of 2015."

"DOCSIS 3.1 is a critical technology for Comcast to provide even faster, more reliable data speeds and features such as IP video to our subscribers' homes by harnessing more spectrum in the downstream," said Tony Werner, Executive Vice-President, Comcast. "By more effectively using our cable plant to grow our total throughput, we expect to offer our customers more than 1Gb speeds in their homes in 2015 and beyond."
