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.

Durvelle27Don’t forget the part where I mentioned I also have full home security
So do I, but I don't pay $75 a month for it. Being fair, you live in Memphis. Much higher crime rate than where I live.

Durvelle27I see some angry people. Me personally I love Comcast. Been dealing with them for 5 years now with no issues

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

Great, good for you. You pay a crapload of money for a luxury internet connection and are lucky enough to either be in a state where they haven't implemented data caps yet, or are getting a huge discount because of competition in your area because of it.

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.

Technically I’m not in Memphis

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

TheLostSwedeIt's actually kind of expensive, in Sweden some places even have "free" 500/500 or Gigabit connections, depending on what the housing association has negotiated with the service provider. It's obviously not free, but usually heavily discounted and included as part of your management fee. Most of these deals are $10-15 a month in real costs.
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.
US broadband providers are all shit, but Comcast is uniquely shit in its customer service and screwing with customers accoutns and products. They've earned a very nasty reputation even among cable companies.
TheLostSwedeYou pay how much?!?!!?
That kind of connection is half what you pay here, although I guess it's "only" 1Gbps down, but still 50Mbps up over cable...
I have to pay $170 a month for 400/20 service with unlimited data, otherwise it would have a 250GB cap.

You guys and your 1TB luxury caps.......

Let's be honest, there has not been a single good FCC pick for decades now. None of them are worth their weight in salt nor fix the problems our infastructure faces. When the face eating panther party eats the panther of the other face eating panther party I cant help but feel relieved.

Back before I went with Comcast; AT&T was the same. You'd pay for 300/30 around $120 and it had a messily 250GB DATA Cap. What was even worse was if you had their TV service (U-verse) It counted against your 250GB DATA Cap and speeds. So for instance if you had 4 TVs in the household; each box takes away about 15Mbps and at 720P you'd consume a few GB of data after so many hours of watching.

This is where I think municipal fiber needs to be taken seriously. Take EPB in Chattanooga, TN for example. $58 USD for 300Mbps symmetric, $68 USD/month for 1GB symmetric, and $300 USD/month for 10Gbps symmetric. I'd jump on that if it were an option in a heartbeat.

yeah they are all pretty shit to be fair.

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.

And there is the explanation for AT+T's reputation. In my city, they only offer 25 Mbps DSL for the same price as 200 Mbps cable. And since the cable company is using ATT fiber for home internet, there is 0 chanc etha tissue is ever resolved.

Chattanooga is a perfect example, sadly no other city, county, or state has ever copied it. No one is willing to put the legal legwork in. When the local dial up ISP went bankrupt, if I'd had the money, I would have LOVED tobuy it and start stringing up fiber. None of the municiapl governments served by them were willing to make the investment.

The backbone of the internet should absolutely be considered a utility. Local Loop Unbundling witht he backbone provider being prohibited from offering home service should be the norm. But none of the FCC heads have ever accepted such proposals. Too much money in it for them.

there are some small towns in colorado who run their own fiber networks real cheap for the residents there.

at least i think so. colorado is too expensive for my blood though, unless i live in a camper van. lol

There are a few. My aunt, a true mountain person, lives in a community that maintains fiber. Of course, the reason they do it is solely out of necessity, verizon long abandoned the copper lines there and there is 0 wireless service due to the mountains.

I doubt it will, sattelite doesnt work in their neck of the woods for the same reason LTE doesnt, the montains screw with radio signals. Starlink will be both more expensive then what they have now and likely less reliable as well. It also wont offer home phone lines, which are a necessity in that community.

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.

It won't there is no comparison right now with Starlink vs fiber.

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.

That's great and all, but I would rather see them lower prices at least a little and/or have more options in my area. Here in southeastern Michigan we have either crappy DSL from Frontier (suuuuper slow) for people out in the farmland, or Xfinity in the suburbs. There's no other competition, unless maybe you count Verizon hotspots, lol.

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.

Great, so you're paying an extra $10 a month, or $120 a year, for absolutely no reason. If you think there is a reason for data caps, besides screwing you over, I have a warranty on your car I'd like to sell you.

$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.

10Gb down, and 40Mb up, I bet, eh Comcast? Also, with data caps?

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.

ToothlessI pay for 800 down, I get 790 down.

I also pay for unlimited data. It's an option to add on.
How much extra you pay for that? More over, how are people going over their data cap? You get two free "good faith" where you dont have to pay extra for what you go over per year. Ive only ever done it once and regularly consume HD content/streaming.

$10 Extra a month vs $20-$40 a month in overages. $10 is nothing compared to that. And how is it screwing people over. Statically less than 20% of users will ever use 1TB of DATA in a months span. It's a niche area. Not to mention this cuts down on heavy server traffic which would cause speeds to lessen. The same concept applies to cellular providers no longer offering unlimited DATA without a premium. But than again if you don't use 1TB of DATA what's the point in complaining about it.

I easily go over due to streaming, website hosting, and having several gaming consoles.

Comcast is the WORST company. They lie about everything and your bill constantly creeps up. I live in Chattanooga and we have Fiber to the home from the Electric power board as soon as it went active I dumped Comcast so did just about everybody else.They tried everything to get me to stay ,Nope got to hell.
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.

$30 for the unlimited and it'll happen in random months. I typically always hit the 900GB mark and I'm not interested in using those two freebies. My bill is $120 for the unlimited and 800 down.

You're really hitting on all the industry talking points, I really do hope you're getting paid by comcast.
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.

You guys have no idea what being screwed for an internet connection is. I live in an house built just over a year ago, not in the middle of nowhere either, and can not get an IP to offer anything over 4 mbps, yes 4 mbps, for £22.00 a month. I have had no choice but pay £55.00 a month for upto 120mbps mobile broadband for £55.00 a month. That`s with a 1Tb a month limit as well.
