Comcast today announced the successful test of its prototype 10G modem technology, paving the way toward a future in which home users can enjoy even more impressive broadband speeds.

Built by semiconductor giant Broadcom, the modem that Comcast tested is a Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem that is capable of delivering upload and download speeds greater than 4 Gbps, according to a press release shared by the company. This is twice the speed of the fastest internet provider in the U.S., Google Fiber, which maxes out at 2 Gbps.

“10G technology builds on the work Comcast has done over the past several years to build a smarter, more virtualized network,” the company wrote in a blurb regarding the new global industry initiative.

“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.”

Today’s announcement represents yet another milestone that Comcast has celebrated relating to its 10G technology. The company previously successfully completed a 10G connection using a virtualized cable modem termination system (vCMTS) powered by DOCSIS 4.0 technology in October 2021, followed by successful tests of a full duplex chip and a trial delivering 1.25 Gbps upload and download speeds in April 2021 and October 2020, respectively.

  1. I could become my own Netflix…..

    Would love this, but the likelihood it’s rolling straight out to consumers anytime soon.

    I’m sure they will try to sell it to everyone, and every major speed test will show crazy nice numbers. Then when you try to do anything that isn’t a speed test; you will get crap- probably worse than what you have now. If you call to complain, they can schedule a tech to be out somewhere between 1pm and 8pm, somewhere between July and September. He will jiggle some cables at the street, run the same speed test – say it was a bad confjigger adapter and he fixed it, and it will continue to do the exact same thing.

    Also your house will still be a public Xfinity hotspot for the neighborhood.

    Crazy, when we moved in to the new house last Sept. I got a deal from Rectrum that locked in 400/30 for $29.99 for two years.
    When that quits, I’ll probably jump to Google Fiber. I’m so glad to finally be in a neighborhood in KC that is in their service area.

  10. Lucky to have so many options. Verizon, At&t, Google Fiber, Spectrum, Comcast, Sunflower, the unsecured WiFi at a nearby church.

    Comcast sent out a flyer that was for GB speed at $60 a month for life. Whose life? I dunno, but if I wasn’t already getting a deal at $30 a month I may have jumped on that.
    My out of town apartment in Chanute, I get 600/20 for just under $70.

    My hometown of Ellinwood, you might get 100/5 for about $85 a month. It’s either fiber or Hughsnet

    That is a very good question…

  12. Spectrum for me has been decent, until it isn’t. I have had them for a couple of years. My tiny apartment I had they had to come out several times to correct the intermittent outages. Last tech they sent didn’t just wiggle a thingamajigger and call it good. He actually removed the “Band-Aid” and installed a clean line. From that point on it was solid.

    Currently, at the house, it’s been solid, with the exception of a couple of days. There was a utility company in the area and I’m sure there was probably an excavation snag.

    They are consistent for the most part, don’t cap, and I handle everything thru an app. So no outsourced thick accents to deal with so far. For $30 though, it’s been a steal.

    Spectrum has it issues of course, like most utility companies.

    One thing I like about my Spectrum service is my IP address hasn’t changed in 15 years. I don’t know if they inadvertently provisioned me a static address, but it makes my life easy since I work from home supporting datacenters. I have IPSec tunnels going to all of our DC’s. When our software VPN or AD has issues I’m still able to access everything without having to go through RMM.

    Otherwise, their service has been very stable for me for a long time. Might have internet issues once a year, and only for a couple hours.

    I would like more upload bandwidth though. But, that’s the cost of single wire copper internet. You don’t get all that download bandwidth without sacrificing upstream bandwidth.

    That’s kind of cool. On Verizon FiOS my IP address stays static for periods of time when everything is up, and [I]usually[/I] I am provisioned the same address external IP if I have to reboot the router, but there is no guarantee.

    I’ve been relying on noip’s dynamic DNS service for all of my hosting needs, and it has worked very well. If budget were limitless – however – I would definitely have preferred a static address.

    Once we all move to IPV6 (whenever that happens) this will all be moot though. There should be no reason for them to make anyones IP addresses dynamic, unless they do so on purpose just to be dicks.

    As much as the design implementation of IPV6 really annoys me, this is one positive to come out of it all.

    As they would probably say:

    Don’t like it? Go to the competition. Oh right.

    This is why monopolies are typically illegal. At least without significant regulation.

    We really need to grow a pair and get together as a nation and slap the ISP’s. HARD. Either fix this bullshit, or get regulated out of existence. No more of this cash cow nonsense is allowed. You are expected to continually improve services and reinvest into networks.

  17. Had Verizon fios TV and internet… then the other company bought them and I switched to spectrum and went streaming only for tv. It was fine until the intro pricing died and incase paying nearly 100 a month for service. Switched back to fios data only at 1/1 gig and 75 a month. So far so good. If I can get 4gb for a competitive price I’ll look when I want to upgrade my router.

    I wonder how they wire these.

    Comcast themselves will probably use a proprietary all in one Modem/Router/WAP box that most tech savvy people will want to avoid like the plague.

    I presume there will have to be 3rd party DOCSIS 4.0 modem only solutions though. I wonder what outputs they will have in order to connect to the router. 10GBaseT? Some of that 5Gig nonsense?

    I still refuse to recognize any intermediate speed existing between 1 gig and 10 gig.

    Yah I have Fios too. I hate Frontier. But Fios is rock solid, as long as you don’t need their tech support. I just remember my old cablemodem (then Comast, now Spectrum. Same cable box in my alley) and I would lose internet every time it rained hard. Water would get into the alley cable box and we were screwed until it dried out. The cable TV still worked though, wonder what that was about. No amount of complaints or pleas for help from me or my neighbors produced anything. But here we are 20 years later, and it’s still the same leaky box in my alley, covered in stickers of whatever the current company name is today.

    Funny thing is, the Fios fiber access box in the alley is all jacked up too. I think a trash truck ran over it, it doesn’t close any more and the lid just sits on top. I have look in there and seen it completely flooded with water…. yet everything still works. Fiber optic FTW I guess.

    I’ve had mixed experiences with FiOS tech support.

    I find it kind of frustrating that you have to call them to reset your DHCP lease if you swap a router. That was really frustrating when I had to troubleshoot a router problem a while back and was swapping back and forth a lot.

    I guess I could have spoofed the same Mac address, but that’s a pain too.

    I actually called their support line once, and the woman who answered was shocked when I asked her to reset my DHCP lease. She told me she had never had a customer use the proper terminology before :p

    In general FiOS reliability and performance are second to none. In my ~13 years as a customer the service has literally never gone down, even during a major town wide power outage. I keep the ONT box and my router and AP’s on my UPS which kept them up until I could get the generator running and it just kept working as if nothing was awry.

    In those 13 years they have also always given me full advertised speeds.

    Their billing practices and online account management leave something to be desired though. Try to remove the router rental from your bill, and see what I mean. There is no option in the web based system for it, so you have to call them and request it, and it takes being a little forceful to get them to agree as they are CONVINCED that your own equipment couldn’t possibly perform as well as their crappy consumer router/AP’s for gigabit.

    Their bill pay website also locks me out about every third time I use it because it flags my network wide VPN connection exit IP as “suspicious”.

    So it’s a mixed blessing. Comcast is also in my area, but it’s no competition there. Verizon FiOS hands down.

  26. I’ll consider myself lucky. Barely a mile or two from the Comast CO in our town. I can get 600+/~15 Mbps including basic cable and a landline for around $214/mo at truly unlimited data. Could be better, could be far worse. They offer over 1 GBps and occasionally hit over 800 Mbps but we’re happy enough as is.

    Honestly their up stream speeds are normally fine unless you have to do heavy video conferencing and moving around gigs of data when time is a factor. I went with the gigabit up and down stream from fios after having to deal with moving ISO’s around too much. Normally you can do it via RDP but when security is tight it’s best just to do it from the laptop then copy them to the server.
