Comcast tests 10G modem prototype at download speed of 4 gigabits per second

Sign up for gaming leaders, along GamesBeat and Fb Gaming, for his or her second Annual GamesBeat & Fb Gaming Summit | GamesBeat: Into the Metaverse 2 this upcoming January 25-27, 2022. Be told extra in regards to the tournament. 

Comcast mentioned it effectively examined a prototype 10G modem the use of the core era that might ship multigigabit speeds to tens of thousands and thousands of houses.

In a lab take a look at, a complete duplex DOCSIS system-on-chip (SoC) cable modem constructed through Broadcom delivered add and obtain speeds sooner than four gigabits according to moment (Gbps) powered through 10G community era.

It’s the most recent in a chain of 10G milestones from Comcast. In October 2021, the corporate introduced a a hit take a look at of an entire 10G connection the use of a virtualized cable modem termination components (vCMTS) powered through DOCSIS era.

That announcement adopted main 10G milestone bulletins in April 2021 of the first-ever are living lab take a look at of a 10G system-on-chip (SOC) and October 2020, of a tribulation turning in 1.25 gigabit-per-second (Gbps) add and obtain speeds over a are living manufacturing community the use of Community Serve as Virtualization (NFV) mixed with the most recent DOCSIS era.

“The nice power of our good community design is that we’re in a position to exceed our shoppers’ calls for lately, at the same time as we incessantly evolve to fulfill the desires of the longer term,” mentioned Charlie Herrin, president of era, product, and revel in at Comcast Cable, in a observation. “As our 10G adventure continues to boost up, shoppers will take advantage of ever-increasing safety, reliability, and pace.”

10G era builds at the paintings Comcast has accomplished over the last a number of years to construct a wiser, extra virtualized community to assist take care of the weight all the way through the pandemic, when individuals are depending on faraway era greater than ever.

Along with offering a trail to multigigabit add and obtain speeds at scale, 10G updates will ship near-term advantages to shoppers within the type of larger reliability, efficiency, and decrease latency, the corporate mentioned.

Hooked up through Broadcom 10G era, the modem take a look at applied the DOCSIS FDX SoC instrument, which Comcast demonstrated in April 2021, to pair with two cable modem chips to ship the efficiency.

Those had been effectively hooked up over a lab-based hybrid fiber-coaxial community to the vCMTS running in DOCSIS mode. This represents the 1st entire community connection of all-DOCSIS elements which are required for deployment. Builders be expecting the demonstrated speeds — that have been sooner than four Gbps add and obtain — to extend considerably as they refine era at each and every degree of the 10G structure.

“With every new milestone, we get a clearer image of the way 10G applied sciences will liberate the following era of pace and function for thousands and thousands of other folks international,” mentioned Elad Nafshi, senior vice chairman at Comcast Cable, in a observation.

I requested Nafshi how this take a look at other from the sooner one.
“The large information here’s that we consider this to be the sector’s first take a look at of a real 10G (DOCSIS modem,” Nafshi mentioned in an e-mail to VentureBeat. “In our earlier milestones that you simply’ve coated, we’ve demonstrated key developments in 10G community era (node, vCMTS), however that is the 1st time we’re checking out the in-home instrument that may in fact ship those multigigabit add and obtain speeds into thousands and thousands of consumers’ houses.”

He added, “With this announcement we’ve now effectively examined all the key elements that shall be essential to reinforce real-world 10G deployments. With this step entire, we’re now taken with hardening those applied sciences as we stay up for are living trials within the box.”
