Comcast Announces World-First Test of 10G Modem Technology Capable of Delivering Multigigabit Speeds to Homes
Comcast today announced the successful test of a prototype 10G modem using the core technology that will deliver multigigabit speeds to tens of millions of homes. In 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. Today's announcement is the latest in a series of 10G milestones from Comcast. In October 2021, the company announced a successful test of a complete 10G connection using a virtualized cable modem termination system (vCMTS) powered by DOCSIS 4.0 technology. That announcement followed major 10G milestone announcements in April 2021, of the first-ever live lab test of a 10G system-on-chip (SOC) and October 2020, of a trial delivering 1.25 gigabit-per-second (Gbps) upload and download speeds over a live production network using Network Function Virtualization (NFV) combined with the latest DOCSIS technology
A key component of 10G, DOCSIS 4.0 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. "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."10G technology builds on the work Comcast has done over the past several years to build a smarter, more virtualized network. In addition to providing a path to multigigabit upload and download speeds at scale, 10G updates will deliver near-term benefits to customers in the form of increased reliability, performance, and lower latency.
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. These were successfully connected over a lab-based hybrid fiber-coaxial network to the vCMTS operating in DOCSIS 4.0 mode. This represents the first complete network connection of all-DOCSIS 4.0 components that are required for deployment. The demonstrated speeds - which were faster than 4 Gbps upload and download - are expected to increase significantly as developers refine technology at every level of the 10G architecture.
"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.
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.

I got the joke, but found it funny because of its inaccuracy.
'Anti-5G' revolves around the *wireless* technologies and international inappropriate private-public relationships.
Even the most ardent and uninformed anti-5G tin foil hat wants ubiquous fibre networking.
Luddites and anti-technologists on the other hand...
The big money comes from the business installments.
Network providers have no intension to speed up connection for home customers
Lack of competition ruins everything.
Since I have cable internet, it looks like my ISP might upgrade to DOCSIS 4 in a few years of Comcast makes it work well...
At least prices aren't insane here, but as they upgraded my upload speed, I really have no need to update our package with them, as 200/50 is sufficient and we're only paying around $25 a month for it. Obviously no data cap.
I've had a few issues with Comcast and their customer service in the past and I'd rather not have to be bothered dealing with that headache again.
They used to use there down speed as a reason to pick them over verizon but kept telling them that verizon had a much better upload speed and if a message needs to get there and back fast you need both which gaming is a main one for this. How ever Comcast do not permit you to run a dedi server.
I experience the same too, here in Portugal. I have 1000/100mbit glasfibre, works excellent and games do fly with 100MB p/s downloads, however when i ramp up usenet to for example Holland i barely get 600kbps and on servers that supposed to be unlimited. These caps are introduced because ISP's have to pay to other peerings for usage.
It's not a technical limitation, on public websites with speedtest i do get the full 1000mbit and 95mbit upload over a distance of 2400km, they just cap it, even when i turn on SSL and what more to obfuscate the traffic i'm doing in particular. Docsis is still a very competing platform; ive used cable quite alot and its reliability is just excellent.
It just does'nt beat glasfibre obviously but technically you could use cable inside the house while wired with glass outside. You could fully utilitize cable as it was intended.
Another thing that many larger villages, towns and cities have are communal broadband, where the city or even the local power supplier owns the infrastructure and then you can pick between a dozen or so service providers, who then have to compete among themselves to offer whatever deals they want. Both options have helped keep broadband prices down in Sweden, although there are still areas that are only serviced by a single provider and you often pay more there, unsurprisingly. Anything below 100/100 isn't really considered broadband in Sweden these days.
The US could really do with local government owned and operated broadband networks, but from my understanding, that's illegal in many states. Well, I obviously see some news about US broadband providers and they all seems to be more or less terrible from my understanding. Most of them don't even seem to want to be service providers, they'd rather you just gave them the login to your online banking... I was friendly with a chap in Victoria that I came in contact with when I worked at QNAP and he was cursing the Canadian broadband providers. Sadly he passed away rather unexpectedly a few years ago.
I pay $160 monthly for Unlimited DATA and speeds upto 1.2GBps along with Home security. Price has not changed and my service has been solid. In my defense I use wired connections on all my primary devices as well. Latency tends to hover around 10ms though buts that’s still decent for gaming depending on the server.
I just did this pull and mind you this is on WiFi from the other side of my house
That kind of connection is half what you pay here, although I guess it's "only" 1Gbps down, but still 50Mbps up over cable...
