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.

Caring1You missed the funny.
Conspiracy nuts don't care about facts.
Very true. The theorists and opposition alike care not for facts.
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...

Durvelle27Also Comcast doesn't have a DATA cap when using xFI
They do in Utah, last time I checked. Price and policies are likely regional.
R-T-BAgreed. I get my speeds. Don't ask what they cost though, it makes me grumpy.
I pay $85 for my Home fiber line. Business line for the shop however, much more..

ToothlessI pay for 800 down, I get 790 down.

I also pay for unlimited data. It's an option to add on.
Sure, you can pay for unlimited data, but from what they've shown us it's not needed. They can easily support unlimited data cap, they did it a year and half ago during the lockdown periods. The cap is there to "look good" because Comcast says "very few" people need more than 1.2TB a month. Right now it's just that sweet spot they seem to think people are okay with where they can make more money for people that exceed it or want to pay for the option.

The tech for 10Gb fibre connection were there for decade
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.

Another lab test so what comcast bring something to market then talk. Cable customers been suffering long enough with poor upload speeds and just average latency.

neatfeatguyYeah! Alright, Comcast! /s

You can bring faster speeds, but you can't remove the shitty 1TB data cap?
The Hell you have a 1TB data cap. Unlimited anywhere in Canada from any company.

Wow, wasn't expecting all the hatred...
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 hit 4TB before, so, yeah. I don't want to give chance to go over.

I think you will be lucky to see Docsis 4.0 available in the market in the next 5 years with the snail pace the cable industry moves. They have been doing these press releases with lab trails for years now. Most current implemations of cable is Docsis 3.1 on the download side and 3.0 on the upload side, and I don't see them spending the money to upgrade most of the infrastructure which will need fiber much closer to the residence.

The funny thing is, the original ISP we had here had fibre to the basement, then Ethernet form there, but they were taken over by the cable company who seemingly ripped all that out. They still claim to offer some kind of fibre hybrid service, but I don't have too much insight into it. They only moved to DOCSIS 3.1 a couple of years ago and the fastest upload speed they offer is 50Mbps. That said, our cost have kept being discounted every few years and this time around we got an "off menu" deal as far as I can tell with regards to upload speed. They recently replaced our aging cable modem/router with a newer model as well, a the old one was getting flaky, free of cost of course. I can't really complain about their service.

I was on cable until about 2018. And they still call me now trying to get me back with their discounts, which are not bad I was playing like $25 a month for a year of 500/20 back then. But in area's with no competition no discounts. And i've heard of simliar stories with an ISP getting bought out by cable then they rip up the fiber and go with coaxial cable which doesn't make sense to me but it is what it is. They still have alot of legacy equipment out in the field they want to make money off of so they will continue at their pace. I do think the Data caps need to go like right now kinda silly in 2022 in the post pandemic world we live in with alot of people working from home.

The pains of being limited by ISP providers in the area. I could look to going to Comcast's gigabit service, but they always try to finagle bullshit into their contracts and stick you with a shitty price hike after 1 year is up into your two year contract. I'm not looking to spend an extra $70-75 a month (after taxes) for gigabit service from them.

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.


1st customer service issue was 12 years ago or so. I originally setup my internet service through Earthlink about 5 years prior to this incident. Little did I know, Earthlink just ran their service through Comcast. Fast forward 5 years or so after I originally setup my internet and Earthlink transferred all accounts to Comcast. In the process of consolidating data on Comcast's end, the main email address tied to my internet account was overwritten (it was an email through earthlink.net or .com or whatever it ended in) and replaced with a comcast email. This flagged my account as being inactive and my internet service stopped working one afternoon. I figure maybe it's an outage, no big deal. Next day, internet still not working. I do all the TSing on my end, no internet. I call comcast, they say internet is not down in the area and want me to go through all the bullshit troubleshooting I've already done. I tell them I did all that and nothing is working, I asked if they could reprovision the modem and struggled getting some one to help, all testing on their end and they couldn't connect to the modem. They setup a tech to visit the next day. Tech shows up, brings a new modem, makes sure everything is connected and no matter what he does he cannot get the modem to connect to the internet. Several hours of doing stuff, no luck. He gave up and left.

Day 3 with no internet. Tech returns, a second new modem. He hooks it up, but no internet. He's on the phone with customer service for a few hours and they can't get it figured out. They continue to look into things on their end.

Day 4 with no internet. I get a call from Comcast, they said they figured out the problem was on their end with the system merge and having something to do with the wrong email linked to the account and they're unable to delete the wrong email and input the correct one. They were working on an internal resolution and would let me know when it's resolved.

Day 5 with no internet. I get a call late in the afternoon from the tech that's been by a couple of times already. He's in the area with a 3rd modem and says he has to hookup this modem and they should have internal issues resolved. Tech shows up, swaps modems and in about 15 minutes the internet is back up.

I requested a refund for days I was without internet due to it being their fault, they said no (ass hat wearing bitches).


2nd customer service issue was about 5 years later. I got a letter in the mail saying I wasn't paying modem rental. No back charges will be applied to my account for the past "missed" rental months, but at the start of the next billing period I would see an extra $10 a month charge for renting their modem.

Screw that. I went and purchased my own modem. I contacted customer service, told them I wanted to get my own personal modem setup and to return the rental. About 20 minutes later I have my modem setup. The next day I drive 15 miles out of the way to return the rental modem to a physical Comcast/Xfinity location. I return it. I get a signed receipt of it being returned. A month later I get my bill and I'm being charged $10 for rental.

For the love of.....I call customer service, get the run around. Let them know I still have the paperwork about returning the rental modem. I send them a copy. Issue is resolved.
(okay, so this one wasn't that bad, just annoying)


3rd customer service issue was after disputing the rental fee, my next billing period I see I'm being charged $25 more than I was before. I reach out to customer service and the guy on the phone tells me that I signed up for a "new contract". I told him I did no such thing. I had to argue with the guy for an hour to get the charges reverted. I couldn't figure it out, but for some dumb ass reason they magically put me on some TV+internet plan because it would "save me money". I ended up getting some cable box in the mail, that I had to drive to the physical store location and return it. Once I returned it, I had to argue with customer service on the phone for another hour about the bullshit contract they put me on without my permission. I got the contract removed because they couldn't find any signature or e-signature from me agreeing to a new contract. I eventually got back to the normal, internet only plan and I was back to paying just my $50 a month.


As you can see, I don't want to deal with their piss poor customer service anymore. I'd hate to sign up for gigabit service, get some run around and end up with them trying to give me the shaft. No thank you.

Yeah i been hitting them up for a discount for about 8 years, so 200\10 for $50 ( should be $80 ) with no cap for a long time. I guess they were losing people to Verizon so had to do some thing about it and as soon as there is no competition they would change in a instant.

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.

It depends if you've been stuck with only cable as an option for the last 2 decades, and they've doubled the price to $100 minimum for cable internet where I live in Canada, so yeah, the cable company is hated.

Datacaps are imposed to assure that the ISP itself is'nt paying too much to other peerings; basicly from what i understand is that outside certain peerings ISP's have to pay. Perhaps they just charge comcast quite alot.

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.

It'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.

I pay $80 USD/month for 960/42. If I got a bit more upload, then I'd be completely satisfied.

I 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

Ouch! Good grief that's expensive! That's almost twice what I pay and you get a slower service. Through our local fiber provider we get unlimited 1gbps full-duplex for $50 per month. I pay $35 extra for higher speeds. Comcast is fleecing you..

That kind of connection is half what you pay here, although I guess it's "only" 1Gbps down, but still 50Mbps up over cable...
