PHILADELPHIA – Comcast announced yesterday it successfully tested “a prototype 10G modem using the core technology that will deliver multigigabit speeds to tens of millions of homes,” a press release says.
In what Comcast says was a world-first lab test, “a Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem built by Broadcom delivered upload and download speeds faster than 4 gigabits per second (Gbps) powered by 10G network technology,” the release explains.
DOCSIS 4.0 is a key component of 10G – it “is an evolutionary leap forward in the ability to deliver multigigabit upload and download speeds over the connections already installed in hundreds of millions of homes worldwide.”
“Connected by Broadcom 10G technology, the modem test utilized the DOCSIS 4.0 FDX SoC device, which Comcast demonstrated in April 2021, to pair with two cable modem chips to deliver the breakthrough performance,” according to the press release.
“These were successfully connected over a lab-based hybrid fiber-coaxial network to the vCMTS operating in DOCSIS 4.0 mode.”
Yesterday’s announcement is the latest in a series of milestones for Comcast in 10G.
“With each new milestone, we get a clearer picture of how 10G technologies will unlock the next generation of speed and performance for millions of people worldwide,” said Elad Nafshi, senior vice-president of next generation access networks at Comcast Cable, in the press release.
“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.”
According to the press release, “10G is a global industry initiative to stay ahead of consumer demand by developing and deploying new network technology to dramatically increase upload and download capacity in the coming years.”
