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.
10G technology builds on the work Comcast has done over the past several years to build a smarter, more virtualized network. In addition to providing a path to multigigabit upload and download speeds at scale, 10G updates will deliver near-term benefits to customers in the form of increased reliability, performance, and lower latency.
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.
“These 10G technologies represent the fastest, most efficient path to deliver multigigabit symmetrical speeds at scale everywhere, not just in select neighborhoods or towns,” said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable.
The pace of 10G innovation is only accelerating, and Internet users around the world will reap the benefits.
Comcast also demonstrated how its DAA network virtualization technology will deliver not just ultrafast 10G speeds, but also greater reliability and adaptability to support a range of next-generation network architectures. The DAA demo included two key components:
Comcast also offered a first look at a 10G node that will become a key element of 10G trials and deployments.
Today’s demonstration builds on several 10G milestones Comcast has announced over the past year, including a test in January of the world’s first 10G modem technology delivering 4Gbps symmetrical speeds.
