Comcast effectively tests 10G cable modem network

Comcast has effectively tested 10G information transfer on its cable modem network. That’s a step on the road to offering 10-gigabit-per-second online bandwidth in each directions on its cable network.

Comcast mentioned its group performed what it believes to be the world’s initially test of a 10G connection from the company’s network to a modem. To do this, the group activated a virtualized cable modem termination method (vCMTS) powered by Full Duplex DOCSIS 4. technologies.

Elad Nafshi, senior vice president for next generation networks at Comcast Xfinity, mentioned in an interview with VentureBeat that the corporation has been working on 10G technologies more than the previous 18 months with the purpose of delivering the next generation of speed and functionality to hundreds of millions of individuals worldwide.

This week, the corporation is celebrating the milestone at its annual 10G occasion at the Virtual SCTE Cable-Tec Expo 2021 occasion. Whatever you consider of 10G, it sounds superior than 5G, which mobile phone providers are touting as competitors for broadband in the home. Competing against new 5G networks is not straightforward for cable providers for the reason that cable networks have been made a lengthy time ago to bring Television shows into the home, not the online, and not at the higher speeds offered today.

The significant benefit of complete duplex and other 10G technologies is that they will unlock multigigabit upload and download speeds more than connections currently installed in properties worldwide, without having the have to have to dig up yards and neighborhoods across the nation.

This week’s demonstration, performed by technologists in Philadelphia and Denver, builds on the 10G milestones announced in April and last October. In the live lab demonstration, Comcast was capable to connect all of the essential network components essential to provide 10G signals from its network to the neighborhoods and properties of prospects.

I asked Nafshi when we could get a rollout of the technologies, but he mentioned he wasn’t capable to give that estimate, as there is a lengthy road ahead.

In order to full the complete connection, DOCSIS 3.1 modems have been configured to operate in the FDX band. Comcast is working with tech partners to create amplifiers to work in the DOCSIS 4. networks.

Back in April, Nafshi talked about the initially chips that could serve as nodes on the network.

“It’s pretty exciting to see these things come together,” he mentioned.
