Comcast Demonstrates Fastest-Yet Speeds Over a Complete 10G Connection on a Live Network

Comcast, the nation's largest gig-speed Internet provider, today demonstrated the fastest-yet speeds it has achieved over a complete 10G connection on a live network, reaching download speeds faster than 8 gigabits per second (Gbps) and upload speeds faster than 5 Gbps. At an industry 10G event at CableLabs headquarters, Comcast also showed the 10G node technology that will help power its deployments and demonstrated how its network virtualization technology will seamlessly orchestrate mixed fiber and 10G deployments. 10G is the technology that will enable Comcast and other network operators to deliver multigigabit symmetrical speeds - combined with improved latency, security, and reliability - over the connections already installed in tens of millions of homes and businesses worldwide.

For the demo, Comcast connected a 10G-enabled Virtualized Cable Modem Termination System (vCMTS) linked by more than 80 kilometers of fiber to the demonstration site. The fiber terminated into a production switch, which connected to what is believed to be the world's first fully functional 10G-enabled Full Duplex DOCSIS 4.0 node, along with a 10G prototype modem at CableLabs headquarters. Today's demonstration is a first in a production-ready network environment, showing how live 10G deployments will work, orchestrated by Comcast's Distributed Access Architecture (DAA) technology, which is already widely deployed.
