Comcast has successfully tested a prototype Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem.
The Broadcom modem was able to deliver upload and download speeds faster than 4 gigabits per second over ‘10G network technology’.
It’s the latest in a series of 10G milestones reached by the US cablenet, which last October tested a complete 10G connection using a virtualized cable modem termination system (vCMTS) powered by DOCSIS 4.0 technology.
“The great strength of our smart network design is that we are able to exceed our customers’ demands today, even as we continuously evolve to meet the needs of the future,” said Charlie Herrin, President of Technology, Product, Experience at Comcast Cable. “As our 10G journey continues to accelerate, customers will reap the benefits of ever-increasing security, reliability, and speed.”
The first live lab test of a 10G SoC took place in April 2021.
