DOCSIS 3.0’s Transformative Moment

6/28/2010 12:01 AM Eastern

As the Federal Communications
Commission continues promoting
an ambitious National Broadband
Plan, with a key goal of bringing affordable
data services at 100 Megabits
per second to 100 million homes,
cable already is playing a leading role
to meet, and even exceed, part of that

The cable industry is
transforming the nation’s
households and economy by
delivering advanced highspeed
Internet connectivity
to consumers and businesses.
Cable’s ongoing rollout of
DOCSIS 3.0 technology in
much of the nation will provide
100-Mbps data speeds to
households, addressing one of
the FCC’s key goals.

DOCSIS 3.0 is poised to
reach maximum market penetration.
Research firm Pike &
Fischer forecasts that the nation’s
biggest cable operators will have
systems in place that can cover close to
100% of their service areas with DOCSIS
3.0 capabilities by the end of 2010. Other
cable operators are expected to cover
100% of their territories before the close
of 2013.

To deliver 100-Mbps broadband
speeds, cable operators are evolving
their existing networks with two powerful
technology weapons: Fiber Deep and,
in some cases, fiber to the home.

Cable operators are pushing fiber
deeper into their networks to support
faster data speeds. Fiber Deep reduces
the number of active components in a
cable network, which in turns reduces
power costs by as much as 50%. Overall,
Fiber Deep can help cable operators
reduce operational and maintenance
costs by as much as 65%, thus improving
their operating performance.

Cable operators also are pushing fiber to the doorsteps of households and
businesses in a number of low-density
markets with RFoG (Radio Frequency
over Glass) technology. Rural regions
represent a tremendous opportunity
for cable fiber deployments, given that
it’s more cost-effective to build RFoG
networks in low-density areas than in
higher-density urban and suburban

Cable also is deploying other technologies,
such as digital return, to
deliver advanced high-speed data services
to consumers. Digital
return addresses returnpath
issues associated with
upstream channel bonding
within DOCSIS 3.0 deployments.
Through this type
of solution and others, cable
can make DOCSIS 3.0
an even more powerful,
two-way platform for highspeed-
data services.

In addition, the cable industry
is ready to support
broadband plan initiatives
intended to stimulate the U.S.

Cable is delivering robust
broadband to businesses of all sizes,
in some cases offering Gigabit Ethernet
connectivity and carrier-class reliability
to the enterprise sector.

For small- and medium-sized businesses,
cable operators provide competitive
and reliable high-speed data
services with the current networks
they have in place. With a sturdy and
affordable broadband connection, cable
operators can help these small- and
medium-sized businesses reach a global
audience with products and services.

Regulators want reasonably priced
high-speed Internet connections for
consumers and businesses. Cable can
meet — even exceed — the national
broadband plan’s goals for delivering
ultra-fast, ubiquitous and affordable
data services.

With cable operators evolving the networks
they have in place, and by minimizing
operational expenditures and
other costs, cable can help transform the
nation’s broadband landscape.
