Comcast will feature a 10G prototype modem for home broadband

Comcast revealed that they have successfully tested a new DOCSIS 4.0 prototype module designed to bring 10G technology into customers' homes for the first time.

According to the broadband provider, the new unit has symmetrical download and upload speeds in excess of 4 gigabits per second (Gbps) thanks to the “Full Duplex DOCSIS 4.0 system-on-chip (SoC) . ” While these numbers have been collected in a laboratory environment, Comcast argues that the new model is capable of even faster data transfer rates in the future, as the company continue to run the eponymous 10Gbps enabled transfer rates promised by 10G networks.

The cable company's product announcement is just the latest stop on the long road they have been on to enable 10G technology for consumer broadband. Previous milestones have included testing 10G connections over a virtual cable modem termination system (vCMTS) using the same DOCSIS 4.0 technology found in the 's new modem and earlier testing of 10G SoCs, which used Network Function Virtualization (NFV) technology and Comcast's live residence. network to reach 1.25Gbps less.

The use of the existing national network is a key objective for Comcast, which stated that DOCSIS 4.0 can allow 10G transmissions through the existing cable infrastructure, and that only the modem at endpoints in consumer homes is likely to be replaced in most markets.

Comcast clearly sees 10G technology as the future of its home broadband offerings, noting that it can even exceed 4Gbps “as developers upgrade technology at all levels of the architecture 10G. ”

For comparison, the company's residential broadband plans are currently being rolled out in most areas with their Gigabit line, which offers download speeds ranging from 1Gbps to 1.2 Gbps, with some select regions accessing their Gigabit Pro service, which rises to 2Gbps. However, these fast plans currently only support much slower upload rates of just 35Mbps. Comcast has previously been called upon to hide this fact by Ars Technica, who noted how difficult it is to find the true level of uploads across the company's various signature pages.

While download rates tend to be far more important to the average consumer than upload rates, Comcast has a relatively slow upload speed as something that broadband broadband companies hold as an advantage over. Many fiber-based plans from companies such as Verizon and Google already offer offset rates that reach or come close to 1Gbps up and down. In addition to the faster download speeds, the symmetrical transfer rates promised by this new modem may be just as important for customers that Comcast was never able to capture with the existing slower uploads.

The company did not provide any timetable for making this technology available to the public.
