Comcast Achieves Speeds Above 4Gbps With Latest 10G Modem Test

What just happened? Comcast has successfully tested a Broadcom 10G modem that delivers over 4 gigabit per second (Gbps) download and upload speeds. The DOCSIS 4.0 system-on-a-chip (SoC) full-duplex cable modem used in the tests was a prototype and was connected to a laboratory hybrid fiber/coax network. Comcast stated that this was the first full network connection of all DOCSIS 4.0 components required for deployment.

ISP next marked that DOCSIS 4.0 will be compatible across connections already installed in hundreds of millions of homes around the world, so there’s one less problem in terms of infrastructure support.

Comcast’s results are certainly impressive, but that’s just the tip of the iceberg. It is expected that as developers improve the technology, the speed will increase significantly. After all, the initiative is called 10G, and their ultimate goal is to provide Internet speeds of 10 gigabits per second.

Comcast has made significant progress on the project lately. For comparison, similar test in October 2020 managed to achieve a stable speed of 1.25 Gbps only on a residential connection.

Unfortunately, Comcast hasn’t said when 10G service will be ready. Considering they haven’t reached half of the project’s speed goal yet, it may be some time before the service becomes commercially available. Those looking for the fastest connection will have to make do with whatever is available in their area at the moment. For me personally, it looks like 1200 Mbps.
