World-first 10G amplifier test achieved
symmetrical speeds faster than 4 Gigs
Technology paves way to deploy 10G to tens of
millions of customers, over the connections already installed in
their homes
Comcast today announced a successful test of the final technical
component necessary to deliver multi-gigabit symmetrical speeds –
powered by 10G and DOCSIS 4.0 – throughout its entire network. With
this test completed, Comcast will launch live trials later this
year, and will begin delivering 10G-powered multi-gig symmetrical
services to customers before the end of 2023.

Comcast previously completed successful, world-first tests of
10G network and modem technologies, including demonstrating a
complete network-to-home 10G loop. The test announced today at SCTE
EXPO, showed the ability to deliver Full Duplex DOCSIS 4.0 (FDX)
services over newly designed FDX amplifiers. FDX was originally
designed for network environments without radio frequency
amplifiers, so the new FDX amplifiers make it dramatically easier
to extend the benefits of 10G to every customer within reach of the
network.
For the test, Comcast inserted new 10G amps, built on a
Broadcom-developed reference design, into a complete 10G network
loop using previously tested DOCSIS 4.0 modem and network
technologies. The team demonstrated download speeds of 6
gigabits-per-second (Gbps) and upload speeds of 4 Gbps across a
complete six-amplifier cascade, sometimes called “N+6”. This
architecture is inclusive of the vast majority of the Comcast
network and is easily and quickly replicated where network
environments may differ. As a result, the successful test is key to
delivering 10G to all Comcast customers.
“With this test, we’ve gone beyond proof of concept. We know we
can use this technology to deliver multi-gigabit symmetrical
services throughout our network and, in fact, we’re confident we
have the potential to go even faster,” said Elad Nafshi, EVP &
Chief Network Officer at Comcast Cable. “With the key components of
10G tested and proven – and our digital, virtualized network
architecture ready to support them – we turn our attention to
extending the full benefit of 10G directly to our customers,
including lower latency, greater reliability, and enhanced
security.”
Following the successful tests of 10G modem and network
technologies, the 10G amplifier technology was the final core
element of the 10G ecosystem that needed to be tested to ensure 10G
technology could effectively serve Comcast’s entire network. As
with previous network evolutions powered by DOCSIS – and unlike
some other technologies –10G allows Internet providers to deliver
enhanced speeds and performance to hundreds of millions of people
over the connections already installed in their homes, without the
need to dig up yards and neighborhoods, or pick and choose who gets
faster speeds and who doesn’t.
In addition, the technologies that power the 10G evolution will
drive significant improvements in latency performance, delivering
even better experiences with latency-sensitive applications like
gaming, videoconferencing, and telehealth, while also unlocking the
potential for a new generation of ultra-low-latency connected
experiences.
Over the past 24 months, Comcast has made significant advances
in 10G technology, including several world firsts. The company has
conducted successful tests of all the technical components
necessary to deliver 10G speeds to customers and is now looking
forward to beginning live trials. Earlier in the month, the company
announced the start of a nationwide rollout of multi-gig Internet
speeds – which will reach more than 50 million homes and businesses
before the end of 2025 – making it the largest- and fastest-ever
multi-gig deployment in the United States. And now with this final
successful technical test of 10G amplifier technology, it will
begin delivering 10G-powered multi-gig symmetrical services to
customers before the end of 2023.
