First-of-its-kind test, using 10G DOCSIS 4.0
technology, delivered 4-gig upload and download speeds, with
capacity to go faster
Comcast today announced the successful test of a prototype 10G
modem using the core technology that will deliver multigigabit
speeds to tens of millions of homes. In a world-first lab test, a
Full Duplex DOCSIS 4.0 system-on-chip (SoC) cable modem built by
Broadcom delivered upload and download speeds faster than 4
gigabits per second (Gbps) powered by 10G network technology.

Today’s announcement is the latest in a series of 10G milestones
from Comcast. In October 2021, the company announced a successful
test of a complete 10G connection using a virtualized cable modem
termination system (vCMTS) powered by DOCSIS 4.0 technology. That
announcement followed major 10G milestone announcements in April
2021, of the first-ever live lab test of a 10G system-on-chip (SOC)
and October 2020, of a trial delivering 1.25 gigabit-per-second
(Gbps) upload and download speeds over a live production network
using Network Function Virtualization (NFV) combined with the
latest DOCSIS technology.
A key component of 10G, DOCSIS 4.0 is an evolutionary leap
forward in the ability to deliver multigigabit upload and download
speeds over the connections already installed in hundreds of
millions of homes worldwide.
“The great strength of our smart network design is that we are
able to exceed our customers’ demands today, even as we
continuously evolve to meet the needs of the future,” said Charlie
Herrin, President of Technology, Product, Experience at Comcast
Cable. “As our 10G journey continues to accelerate, customers will
reap the benefits of ever-increasing security, reliability, and
speed.”
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.
Connected by Broadcom 10G technology, the modem test utilized
the DOCSIS 4.0 FDX SoC device, which Comcast demonstrated in April
2021, to pair with two cable modem chips to deliver the
breakthrough performance. These were successfully connected over a
lab-based hybrid fiber-coaxial network to the vCMTS operating in
DOCSIS 4.0 mode. This represents the first complete network
connection of all-DOCSIS 4.0 components that are required for
deployment. The demonstrated speeds – which were faster than 4 Gbps
upload and download – are expected to increase significantly as
developers refine technology at every level of the 10G
architecture.
“With each new milestone, we get a clearer picture of how 10G
technologies will unlock the next generation of speed and
performance for millions of people worldwide,” said Elad Nafshi,
Senior Vice President of Next Generation Access Networks at Comcast
Cable.
10G is a global industry initiative to stay ahead of consumer
demand by developing and deploying new network technology to
dramatically increase upload and download capacity in the coming
years.
