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
Definition: Parameter 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 worldwide.
Year of the Innovation: 1978
What is the innovation that CommScope or one of its acquired companies was first in creating?
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 television industry.
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 together?
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.
