Comcast announced its multigigabit symmetrical Internet connection powered by 10G and Full Duplex DOCSIS 4.0. 10G technology.
Comcast said its investment in the broadband innovation will revolutionize the availability of ultra-fast speeds, by delivering multigigabit symmetrical services over the connections already installed in millions of homes worldwide, without digging up yards or installing new connections.

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 and 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, said Charlie Herrin, President, Technology, Product, Experience at Comcast Cable.

This live trial is the result of significant investment in 10G technology Comcast has made over the past 24 months, including several world firsts. Comcast in September completed a successful 10G amplifier test.

Comcast 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 in the United States.

“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,” said Elad Nafshi, EVP and Chief Network Officer at Comcast Cable.

Comcast believes that its investment in 10G will drive significant improvements in latency performance, delivering better experiences with latency-sensitive applications like gaming, videoconferencing, and telehealth.
