Comcast mentioned its staff performed what it believes to be the world’s first take a look at of a 10G connection from the corporate’s community to a modem. To do that, the staff activated a virtualized cable modem termination system (vCMTS) powered by Full Duplex DOCSIS 4.0 know-how.

Elad Nafshi, senior vice chairman for subsequent era networks at Comcast Xfinity, mentioned in an interview with VentureBeat that the corporate has been engaged on 10G know-how over the previous 18 months with the purpose of delivering the subsequent era of velocity and efficiency to a whole lot of hundreds of thousands of individuals worldwide.
