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.

vb101Comcast 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.
You really must loathe Comcast if you registered an account here just to comment on this press release. :roll:
Always nice to see people that have a good experience with their ISP and that's coming from some that once worked for one of the very first ISPs in Sweden.

I wasn't even expecting much interest in it, it was just the 10G thing that made me post it, since it was over DOCSIS 4, so something new,

Google fiber in kc is now 2gig download 1 gig upload for $100 month. Fiber goes all the way to the router next to my monitor. This service never goes out and never packet drops lol it’s insane.
Actually on the back of their router/modem it says 10g and I asked the install guy about it and he said gfiber is planning on going for 10 gig download in the future.
My motherboard only has a 5gig port lol

Drone69You 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.
The UK seems to be as backwards as the US and Australia, but still not as bad as Germany, which is quite surprising. Apparently Germany is one of the worst "developed" countries when it comes to getting anything faster than xDSL.
Still remember the green stingray modem from Alcatel in the UK, had to buy a USB 2.0 PCIe card, as my stupid VIA chipset didn't deliver the exact 500mA of power it needed to give me that sweet sweet 512/512 Kbps connection...

EPB in chattanooga is fanastic and that models need to be pushed out to the whole country but shills in government on the payroll of these large cable companies will fight that tooth and nail. And the government doesn't have the balls to do anything about it sadly.

Stuff like this is the reason I check for internet instructure at any place i'm going to rent or buy. Its a basic utility for me and if I don't like what I see I move on. My career is in IT its something I will not budge on.

The cable internet industry it hated by alot of people i'm not surprised by any of these post to be honest.

You don't see to many articles like this about other ISP's

You're the exception rather than the rule, but yeah, that sucks. :(

I had no choice but move here. The housing association claimed they were going to sell the property instead of rent it, but who in their right mind would purchase this property with the pathetic internet connection. I have a terminal illness and this was the first property my daughter and myself could get, she is my carer and we had to take this property or wait years for another home so she could help me during my final year or two.

I'm sorry to hear that hoping Starlink may be an option for you.

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

You are paying $160 for cable internet? Holy. That's why people get fibre to the home, that price is outrageous.

I know. I live right next to the city, not even 1 minute drive outside a town of 20,000 people. Was told by the cable company I need to pay $20,000 to upgrade 500 metres of power poles down my road to carry the heavier weight of cable. That's how I got cable internet... Welcome to Canada.

I`m not sure how many people live in my town but the fact the home was built less than 12 months ago and the UK is supposed to be connecting all new builds to the fiber network sucks monkey balls. I`m fortunate it`s going to my problem for too much longer but my daughter and grandson are stuck with a crappy connection until 5g gets to our town. Fibre is not going to get here for over 5 years. I should add that where I used to live I could get 500mbs broadband and that address could be able to get 1000mbps connections now which really pi**es me off.

Still investing in cable instead of going fibre ? Is that corporate Stockholm syndrome ?

This. To be fair though. Upgrading and maintaining an existing network of cables is far less expensive than replacing it all with fiber. And that is why they are getting left behind. New companies are coming in, laying/hanging fiber lines and making tons of money doing it while at the same time providing better/faster service at cheaper prices. Cable companies and the cable network infrastructure is an obsolete & dying system of tech that has been obsolete for more than a decade. It can't be replaced and destroyed fast enough. Comcast is similarly an antiquated dinosaur of a company and just can't shut down quick enough.

When companies realize that they have to put some things BEFORE profit and investor butt kissing, they will do better.

Yes, I loathe , HATE, Despise ,Comcast. When I stopped my service they sent me a 1500 dollar final bill. They claimed I did not return my Modem and DVR/Cable boxes and that I broke a contract ,
that was special for my house. I was suppose to keep it for X amount of months and I didn't. I had a feeling this would happen, my Aunt/Cousin are a feared business litigators and she told us what to do before hand so I videotaped everything the serial numbers everything . My partner came with with me,Most are bills are in his name but I got stuck with Comcast. I never made some contract and I know he didn't either. They still tried there shit to get me to pay. I went back up there with the video and played it for them. They could plainly see that I did leave it with them . They said that I was underhanded taping them without there knowledge. I told them, When one Sups with the Devil one needs a long spoon but I feel like I just insulted the Devil. That did not stop them they changed there story to broke Modem and DVR/Cable boxes . I recorded everything they said after they changed there story , I lost my temper bad and My Aunt went down there and talked to them and saved her favorite nephew cause , I never heard another word from them. EPB is wonderful , they never raise there rates and if they do they tell you months ahead and it was like two dollars more a month and that's only happened one time in the 8 years I have had them. There nice on the phone and it's none of that smart ass dick head shit Comcast pulls. I think 5G and Fiber to the home will keep on chipping away from there monopoly.

Well, in Comcast's defense, you do enter into an agreement where you say that you'll keep the service for so long and they do say that there will be charges for early termination. Agreements between businesses tend to have the same kind of language too. A lot of this is to help maintain predictability of the offered service and revenue for said service. I guess that the moral of the story is that you should know what you're agreeing to before agreeing to it as you can get service without a contract. It might cost a little more money, but you can.

For the time I had Comcast, there were no contracts. Once again, that might be a regional thing.

lynx29yeah 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.
Or New Zealand's model

ToothlessI pay for 800 down, I get 790 down.

I also pay for unlimited data. It's an option to add on.
CrAsHnBuRnXpHow 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.
Here is what im getting while im playing WoW in the background around 7pm CST. I pay for 1200down 40 up
