Comcast claims ‘world first’ Full Duplex DOCSIS 4.0 10G connection
By
US cable giant Comcast says it has successfully completed what it describes as the world’s first live, multigigabit symmetrical Internet connection powered by 10G and Full Duplex DOCSIS 4.0.
For the live trial, Comcast connected a business location in the Philadelphia region to its live network including a DOCSIS 4.0-enabled 10G node and multiple cable modems to deliver high speed data service to the site.
Comcast engineers tested symmetrical speeds over the connection. Comcast says they will continue trialing 10G technologies over the next several months in preparation for offering 10G-enabled services to customers in the second half of 2023.
Comast says the trial is the result of significant advances in 10G technology it has made over the past 24 months, including a successful 10G amplifier test in October.
The company has announced the start of a nationwide rollout of multi-gig Internet speeds – which will reach more than 50 million homes and businesses before the end of 2025.
“This live trial combines years of technology innovation and versatility to create a clear path to next-generation speed, reliability and performance for all the homes in our footprint, not just a select few,” said Charlie Herrin, president, technology, product, experience at Comcast Cable.
“What excites us most about 10G technology is the ability to continue our longstanding commitment to delivering our best technologies to everyone we serve.”
Elad Nafshi, EVP and Chief Network Officer at Comcast Cable, said: “We started this year with the announcement of our world-first test of 10G modem technology capable of delivering multi-gig speeds to homes and, as of today, 10G is a reality with the potential to transform and evolve the Internet as we know it. It’s been an incredible year of progress, and we look forward to continuing to refine and harden our 10G technology as we work to make this service—and all its incredible benefits—available to all customers in the years ahead.”
