At CableLabs event, Comcast live demo delivers
download speeds faster than 8 gigs and upload speeds faster than 5
gigs, shows 10G applications for network virtualization
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.
“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:
- The demo showed how a single DAA-enabled vCMTS can seamlessly
and simultaneously operate both 10G connections and PON (passive
optical network) connections and deliver multi-gig services with
identical levels of visibility and orchestration. While Comcast is
primarily focused on 10G, the ability to easily blend 10G and PON
provides enormous flexibility to support the widest range of
geographies and customer needs.
- The demo also showed how 10G and DAA will deliver greater
reliability by leveraging the unprecedented visibility the
technology provides into Internet performance at every level of the
network from the core, all the way to individual customer
gateways.
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.
