Broadcom Drives Gigabit Broadband with Industry’s Highest Port Density G.fast Vector Processor
May 19, 2019
Deploying fiber all the way to a customer premise is often costly and challenging to execute, with expensive cable pulls and complex rights of way. G.fast avoids these issues by providing fiber-equivalent speeds over legacy copper wiring. Existing G.fast solutions address lower density installations, but with the BCM65550, operators can now support up to 192 lines of vectored 212MHz G.fast for high density residential sites.
The BCM65550 builds upon Broadcom’s market-proven G.fast modem and embedded vectoring solution, the BCM65400, now supporting production G.fast deployments across the globe. Vectoring, or crosstalk cancellation, requires extensive compute resources, and the BCM65550 delivers this without compromise. Crosstalk is cancelled across all lines with extreme resolution, achieving nearly identical performance to ideal, crosstalk-free environments.
“As demand for gigabit speeds rises, it is crucial that operators address this requirement by moving fibre closer to the customer, but there can be a significant challenge here in regard to costs and logistics especially in high-density MDU markets,” said
“Until now, high-density G.fast deployments lacked a no-compromise system-level vectoring solution,” said
BCM65550 Key Features
- Crosstalk cancellation solutions for up to 192 twisted-pair copper ports
- Hybrid Vectoring to support parallel operation of G.fast and VDSL on a single device
- Proxy Vectoring to offer seamless support for new G.fast cards introduced into a legacy VDSL system
The BCM65550 has been released for mass production. Please contact your local
