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.

Now, imagine, if you will, having a 1.2TB cap on your 1.2Gbps connection, and if you didn't want that cap, it will cost you between $25-30 extra a month. This basically just being for the privilege of using your connection to its full potential.
On top of that, imagine being strapped for cash, and wanting just a base internet connection that.. is useable(DSL often is unusable). The lowest speed internet connection in my area is 200Mbps. They can afford to sell it at $30... for 2 years(for new customers). After 2 years, the cost more than triples to $100.
This reply is here to give you a bit of perspective on just a few reasons why people may not like comcast, because you don't seem to understand.
but Security cost varies depending on number of sensors you have and cameras
I have sensors though out and 4 exterior cameras with 24/7 recording$160mo isn’t a crapload of money by far
and there is indeed a 1TB DATA cap in my area as I use to have one. But Comcast offers unlimited for an additional $10mo which out weighs paying overages every month as I typically use about 2-3TB of DATA monthly
and to the comment being strapped for cash has nothing to do with the ISP. The ISP can price there services as they please based on the demand and area. ISP has no obligations to lower prices. So when is comes down to it if you are strapped for cash maybe look outside of having broadband internet. There are other options available. I know many who use hotspots for internet from the cellphones that have unlimited DATA. Or for instance in TN AT&T offers a special package for households with lower incomes internet with speeds upto 100Mbps for only $15mo
the great thing about being a consumer is you have choices
You guys and your 1TB luxury caps.......

i just thought it was funny lol
comcast is about as scummy as scummy gets :roll:
the fact internet is not treated as a public utility yet is pathetic. our tax payer money goes to subsidize these scummy corporations for years, including Starlink I believe, and they don't do **** for the avg person, would be better if it was like Japan's model.
at least i think so. colorado is too expensive for my blood though, unless i live in a camper van. lol
Starlink DOES hold great promise for middle america, living in small towns or rural areas, where there is no high speed internet. A few of the farmer communities I grew up in are, to say the least, very excited.
Fiber is much faster and can handle far more bandwidth currently.
The speeds you get on starlink right now are comparable to a docsis cable connection and that is no competition for a fiber connection.
Unfortunately, until we get fiber in this area, prices will stay high.
I pay something like $110 a month for 1,200 mbps down and like 40 mbps up, but that comes with a data cap unless I A) rent the Xfinity modem for $10 a month and B) pay $15/month for unlimited data. If I still had my own modem it would have been $25/month for the unlimited data, so I figured just go back to the Xfinity modem since it would shake out to be about the same and at least then they'll support it.
I personally don't mind paying $135+tax for very high speed (and reliable at least in my area) internet, but that doesn't mean I wouldn't like to see their effective monopoly end in my area. As soon as fiber is in my area (a suburb of Detroit) I'll jump immediately to it.
$160 is a lot(almost $2k a year), but again, more importantly, $100 for 200Mbps down is outright robbery, and we can see this by the ability for comcast to afford to charge $30 for the first 2 years of a 200Mbps connection before upping the price 3x.
Are you part of Comcast customer service? Because you sure do seem to be oddly loyal to a corporation that only cares about your money, as seen with the unnecessary unlimited data cap charge.
I was paying $150/mo for Cox gigabit internet until July of 2020. That was for 1Gb down 40Mb up. Plus an extra 500GB of data because I was constantly butting up against Cox's 1TB data cap (data caps are stupid). Then GoNetspeed finally built out in my town and I have FTTH installed.
$90/mo for 1Gb symmetrical, no data caps, lifetime price guarantee. Also has been more stable than my Cox coax.
Fuck the cable industry.
I have 1 gig and its one gig up and down always 68 bucks a month no data caps. I have some friends that have the 10g and the speeds are unreal , full 4 k movie in a few seconds.
That 10g costs 300 bucks a month way to pricey for my blood . Comcast threw every lawsuit they could at Epb to try to stop them from deploying it . It's totally changed Chattanooga
that was one of the reason that got Volkswagen here and Amazon.
1. I'm still struggling to understand how you feel grateful to have to pay $10 for a data limit that doesn't need to exist(in most places it is $25-30 extra).
2. The less than 20% data talking point, which used to be something like 5%. Looks like they changed the number significantly. If 20% of people go over that cap, it's screwing them over whether or not they're paying the $10+ for "unlimited data", simply because again, the data cap does not need to exist.
3. Speeds slowing down due to traffic: Comcast profits are measured in tens of billions of dollars a year. This is profits, not revenue. If you don't think they have money to upgrade absolutely every bit of their infrastructure nation wide to ensure speeds are not reduced without a data cap, I have alien invasion insurance to sell you.
I guess you haven't kept up with Cell phone plans in the last 5 years or so. What I'm about to say is true for the big 3 mobile companies in the US(T-Mobile, AT&T & Verizon). None of them have hard data caps anymore, they simply have soft caps and slow down speeds once you hit them so you can only use the most basic of internet.
