Top 10 CommScope Innovations: P3 Design and Process for Coaxial Cable
Note: we have been revealing in recent blog posts the top 40 innovations made by CommScope (or one of its acquired companies) as part of our 40th anniversary celebration. We continue today by revealing an innovation from the final grouping of innovations—the top 10—which are being announced in alphabetical order. These are our all-time greatest product and technology innovations. You can also review the complete list of innovations we’ve revealed so far and read more about the overall program and selection process in this November 4 post.
CommScope’s Top 40 Innovations—Grouping 1-10
P3 Design and Process for Coaxial Cable
III (P3) coaxial cable based on 75-ohm closed cell gas expanded foaming
technology. CommScope-developed proprietary method of producing a physically
more robust and lower lost coaxial cable, soon becoming the industry standard

What is the
innovation that CommScope or one of its acquired companies was first in
Accomplished in 1977 and first marketed in 1978, P3 was the
first practical cable used by the nascent cable television industry, and it
became the industry standard product that is
still in use today. P3 was the industry’s first 75-ohm, consistent,
low-attenuation, high-quality product, and it helped launch the cable
What was happening in
the market that this innovation was needed?
Cable TV operators wanted to expand their service areas to
reach new customers, but older cable technologies (P1 and P2) didn’t provide
the required reliability and performance. P1 cable was the first generation – its
foam core didn’t have the dielectric properties needed to offer the low
attenuation required to deliver broadband signals over long distances. P2 cable
had lower density foam and solved the attenuation problem, but its polystyrene dielectric
material was brittle and subject to moisture absorption.
P3 used low-density closed-cell foam so it was flexible and watertight and had
lower attenuation for higher bandwidth-carrying capacity. P3’s introduction led
to the displacement of P1 and P2 in the market.
How did this
innovation benefit customers and the industry?
As the first practical, high-performance cable in the cable TV industry, P3 made it possible
for cable companies to expand rapidly and grow into the giants they are today. P3
helped put the cable TV industry on the map as a telecommunications competitor,
and supported these companies’ expansion into data services in the 1990s. P3
enabled high-speed data transmission to every home at a time when the telcos
were stuck with twisted pair copper because building fiber-to-the-home networks
was not yet practical. As a result, cable companies gained a significant
advantage in the emerging Internet connectivity market because P3 cable delivered
50 times as much bandwidth as twisted pair copper.
Did this innovation
act as the springboard for other innovations, and if so, how do they all tie
Quantum Reach (QR) cable was an evolution of P3 that followed
in 1984. QR offers a thinner outer shield, lower attenuation at the same
outside diameter, and a welded outer conductor. Significantly, QR uses the same
closed-cell foam technology as P3. QR was more flexible, but by 1984 the
industry had standardized on P3 connectors, so QR cables were never the
preferred choice because P3 and its connectors were ubiquitous. P3 technology
also was transferred into CommScope’s early 50 Ohm product line, Cell Reach, which served cellular customers and is sold today as CommScope’s
FXL product line.
What is the
significance of the innovation for CommScope?
P3 was key to CommScope’s early growth in the cable
television market and became a springboard into the cellular cable market. With
P3, CommScope built a reputation that served it well as it rolled out
additional CATV products into the market. CommScope has always had the majority
market share for P3 cable, and this product has contributed billions of dollars
in revenue to CommScope.
