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.

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

When companies realize that they have to put some things BEFORE profit and investor butt kissing, they will do better.
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.
Anyway, I'm late to the party here, but I need to rant a little bit. My problem with Comcast was never the service, which for the most part worked very well, with very few interruptions. My problem is that they're lying scumbags. I'm sure everyone is familiar with the cliche that cable companies will slowly ramp up your bill, sight unseen, until you have to gird your loins for an hours-long fight/renegotiation, every year or two, to get the cost somewhat under control. But Comcast went even beyond that. By the end I was paying ~$200/month for a "triple play" plan that I didn't want. (Triple play being phone/internet/television--Oh, and NB: I wasn't even renting a cable box. That would have added $15.)
Every time I tried to downgrade to just internet, they'd swear that triple play is the only thing available in my area, and that I had the cheapest version of it--a facially absurd claim. The best part is that during this time, if I went to Comcast's website, I'd see advertised plans "for my area" that were markedly cheaper, or didn't include TV/phone. These plans would promptly disappear the moment I logged in to inquire further.
But Comcast was the only option around here for a very long time. About three years ago, Verizon Fios finally arrived, and I quickly switched. I had to hold my breath even in the final call with Comcast, though, as they are notoriously difficult when it comes to letting people cancel. Happily I got out without incident, though the call was unnecessarily long and I had to endure the wheedling of at least two reps.
Anyway, right now I pay $90/month for Gigabit internet, which isn't exactly the greatest deal on Earth. And I'm under no illusions that Verizon is some sort of shining white knight; it's a sociopathic mega-corporation just like all the rest. But at least with Fios "$90" is $90. They aren't charging me any extra fees or taxes. There is no modem rental fee with this plan either, so I don't even need my own equipment to avoid that. A "$90 plan" from Comcast would probably cost you $120. And then $150 a year or two later, until you spend five hours on the phone arguing with them to get it down.
On paper, both companies have comparable pricing, but in practice, Comcast's dishonesty adds a ton of extra cost, both in time and money.
Here you can get get 500/25 over cable for 45€/month and 100/40 over DSL for 50€/month. I pay 10€/month for 14 mbps on my phone with a 2.5 GB cap. Fibre is basically nonexistent (gbit in about 14% of homes)
