Broadcom Drives G.fast into the Mainstream with New DSL Infrastructure Device Family
Improving on Broadcom’s production-deployed previous architectures, the BCM65400 incorporates eighth-generation FirePath® DSPs, a new vectoring core, and a complete set of 1G-to-10G datapath interfaces. These new resources allow the family to offer the industry’s lowest power dissipation, scale to the highest line densities, and provide the benefits promised by recent G.fast amendments, including support for the new 212MHz profile, with aggregate speeds of up to 2Gbps, and dynamic time allocation (DTA).
Broadcom’s G.fast solutions offer the unique ability to fall back to VDSL2/ADSL standards, in addition to G.fast, with simultaneous, independent vectoring domains, enabling the operator to update central office equipment independently from the customer premise. Building upon this, the 65400 expands the addressable market for G.fast to point-to-point coaxial cable, often installed in multi-dwelling units (MDUs), apartment buildings and other high-density housing.
“With our second generation G.fast infrastructure chipset, we set out to deliver a scalable platform that system vendors could use for the full range of G.fast system densities,” said
Greg Fischer, senior vice president and general manager of Broadband Carrier Access,
“As we move from G.fast field trials to an expanded pilot, Openreach requires a flexible silicon platform that covers the full range of line densities in our diverse infrastructure and maximizes rate and reach performance,” said
Peter Bell, director network portfolio, Openreach, British Telecom’s local network business. “We are encouraged that
“Gigabit services for consumer households have become the gold standard for connectivity, and service providers have focused investment on deploying PON further into their networks,” said
John Kendall, principal analyst, Connected Home at IHS Markit Technology. “Even as providers provision their networks for next generation bandwidth speeds, DSL is still a very important market segment. G.fast provides a powerful tool for providers seeking to deploy fiber to the most financially sensible point, in order to maximize return on capital investment.”
The Broadcom BCM65400 family of devices is sampling today and available through distributors worldwide.
