Why the future of enterprise cabling has Cat 6A written all over it

Enterprise network infrastructures are under increasing pressure as requirements build. The sheer number and diversity of connected devices and systems are exploding. Network convergence—IT/OT, power/data—is ramping up. At the same time, more resources are being pushed to the edge, extending the network further and further.

Now, more than ever, having an infrastructure platform that can efficiently address these challenges, as well as future ones, is critical. The scope and complexity of the connected enterprise will only continue to expand. There’s a lot riding on your platform selection.

At CommScope, we know a thing or two about network change, and the importance of getting it right. Our 40+ years of enterprise experience and understanding of where the technology is heading all point to the same conclusion: Category 6A cabling and connectivity. Full stop.

On this resource page, we lay out the trends, facts and rationales behind our firm belief that Cat 6A will be the predominant enabler of tomorrow’s more connected and capable enterprise network. Read through our summaries, download our resources, learn with our tools, and watch videos to explore the next sections. We invite you to examine the evidence, then draw your own conclusions.

The evolution of Category cabling and the future of tomorrow’s network


First introduced by CommScope, as SYSTIMAX® GigaSPEED® X10D, in 2004 and standardized in 2009, Category 6A remains the recommended infrastructure for modern new builds. So how did we get here?

In 2004, the industry recognized the bandwidth limitations of Category 5 and Category 6 cabling categories would severely constrain network growth and development. A major challenge was supporting higher data rates over longer distances, compared to Category 6.

Led by the IEEE 802.3an 10GBASE-T Task Force, the search for a 10 GE-capable solution was on. They began by tackling fundamental issues like return loss, crosstalk and noise from adjacent cabling channels (alien crosstalk). Their work resulted in minimum cabling channel specifications for 10GBASE-T and a new class of cabling, Class EA, otherwise known as “Augmented” Category 6. In October 2004 Cat 6A was officially born.

As new applications require better cable performance, adoption rates of Cat 6A have steadily increased. Drivers such as IoT, Wi-Fi 6/6E/7, four-pair PoE, smart lighting, building control/automation, in-building cellular, and more, will extend the uptake of Category 6A for the foreseeable future. Based on the graph, looks like the smart money is on Category 6A.

CAT 6A: Hard facts

Network speed vs span

Network speed vs span: How fast depends on how far

Much of the network’s design depends on where the data is generated and where it must be processed and stored. More network resources are moving to the edge while data speeds and capacity demands keep increasing beyond the capabilities of existing Category 5 and Category 6 networks.

Specifically, Category 5/6 are susceptible to channel impairments created inside the operating environment. Crosstalk, impedance mismatch, external noise, return loss and other issues cause bit errors that can reduce overall throughput. Category 6A cabling is specifically engineered to overcome these challenges, enabling networks to support 10 GE channels up to 100 meters—nearly three times longer than Category 6.

Not just any Cat 6A. CommScope’s family of Category 6A solutions provides enhanced cable and connector performance, so you can support the latest 10 GbE requirements.

Why CommScope CAT 6A?

Podcast: Drilling down on Category 6A

In this podcast, CommScope Enterprise Strategy Solutions Architect Jason Bautista takes you on a deeper dive into the benefits and staying power of Category 6A cabling. Speaking with the editors of Cabling Installation & Maintenance, Jason discusses Cat 6A’s device compatibility, current and future use cases, and more. 



To steal an anatomical analogy, your cabling infrastructure is both the nervous and circulatory system of your enterprise building and campus network. Its function is to transport the data and power that nourish an increasingly hyperconnected ecosystem.

Just as your body’s blood vessels must adapt to handle increases in stress and natural aging, so, too, your enterprise cabling must evolve to meet the rising demands of more performance-intensive applications. We believe the demonstrations show Cat 6A cabling gives you the best chance of success. By providing a long-term platform that can support multiple technology migrations, Cat 6A helps you realize more value from your entire enterprise network investment.

With CommScope as your infrastructure partner, you can optimize the power of Cat 6A. Our SYSTIMAX, Uniprise and NETCONNECT Cat 6A portfolios ensure the product performance, technical support and global availability you need—wherever you need it.
