According to Marucci Sports, the CAT9 Connect combines “optimized barrel design and precision balancing” to create an end-loaded power profile preferred by stronger, elite hitters.

Benefits of CAT9 Connect Composite Cable

CAT9 Connect Composite cables offer several advantages over other cable standards:

Higher bandwidth – CAT9 cables support bandwidth up to 2,000 MHz, allowing for transfer speeds up to 100 Gbps. This is a significant increase over CAT6 and CAT8 cables.

Increased speeds – The higher bandwidth of CAT9 cables enables much faster data transfer speeds compared to previous cable categories. This makes CAT9 ideal for high bandwidth applications.

Supports advanced applications – The high speeds and bandwidth of CAT9 cables allow them to support emerging technologies like 16K video streaming, 5G networks, high-performance computing clusters, and more.

More durable than other types – CAT9 Connect Composite cables use a carbon composite handle and thermally treated alloy barrel for improved durability compared to other cable types like copper ( The composite materials are designed to withstand wear and tear.

CAT9 Connect Composite Cable Structure

The CAT9 Connect composite baseball bat from Marucci uses a unique two-piece design combining multiple materials. The handle is made from a carbon composite while the barrel is constructed from Marucci’s AZR alloy metal.

According to Marucci (, the carbon composite handle features an “Outer Locking System” that interlocks it with the alloy barrel. The handle threads into the barrel and an outer ring secures it in place.

The carbon composite handle provides an optimal blend of stiffness and flexibility. It allows for more flex and vibration dampening than a standard aluminum handle. Meanwhile, the AZR alloy barrel offers a lightweight but strong and responsive hitting surface.

The interlocked two-piece design aims to provide the benefits of both materials. Players get an end-loaded swing weight and the power of the alloy barrel along with the comfort and control of the carbon composite handle.

Compatibility with Other Standards

CAT9 Connect Composite Cable is fully backward compatible with previous CAT cable standards like CAT5, CAT5e, CAT6, CAT7, and CAT8. This means it can be used seamlessly with older CAT-rated network hardware and infrastructure without any issues (1).

The most common ethernet protocols like 10BASE-T, 100BASE-TX, 1000BASE-T, 10GBASE-T, and 40GBASE-T are fully supported by CAT9 cable. So you don’t need to worry about compatibility with your ethernet devices – CAT9 will work with your routers, switches, network cards, and other equipment designed for these protocols (2).

The key benefit of the backwards compatibility is that CAT9 can be installed into existing CAT5/6/7 cable runs with only upgrades to the endpoint hardware (routers, switches, etc). No need to completely re-wire a building to reap the benefits of CAT9 speeds!

Use Cases

While CAT9 Connect Composite Cable is designed for high-bandwidth applications, especially compared to previous CAT cable standards, common use cases are:

Data centers – Due to its ability to support a higher speeds and bandwidth, CAT9 Connect can be useful for connections within and between data centers, especially as data centers continue to increase in bandwidth demand.

High performance networks – For office or campus networks that need to support high speeds, CAT9 Connect provides an upgrade path over CAT6 or CAT6a cable while supporting future bandwidth needs.

High bandwidth applications – Whether its HD video streaming and editing, scientific computing, or other data intensive uses, CAT9 Connect provides the bandwidth capacity needed to prevent bottlenecks in application performance.

Availability and Cost

CAT9 Connect Composite cables are still relatively new to the market, having first been introduced in 2019 by Marucci Sports ( As a result, availability is still limited compared to more established cable standards like CAT6 and CAT8.

Since CAT9 Connect Composite represents the highest performance cable category currently available, it also comes at a premium price point. CAT9 cables are significantly more expensive than lower rated cables like CAT5, CAT6 and even CAT8.

For example, a 1000 ft spool of CAT6 cable sells for around $180, while a similar spool of CAT9 cable costs over $500. The advanced materials and construction required for CAT9 result in cables costing 2-3 times more than CAT6 (

As CAT9 becomes more widely adopted over time, prices may come down. But for now, the cutting edge performance comes at a steep premium over lower rated cabling solutions.

Installation Considerations

CAT9 cable has more stringent installation requirements than lower category cables due to its complex internal structure and sensitivity to interference and signal loss. Proper connectors rated for CAT9 are required, as lower rated connectors may not make adequate contact for all 8 conductors (

CAT9 cable installation is best performed by installers certified for Category 9 to ensure adherence to strict termination procedures. The cable jacket and wire pairs must be properly handled to avoid damaging the internal components (

Using CAT9 cable may also require infrastructure upgrades as it may not be compatible with older patch panels, jacks, and ethernet switches. The connected hardware must be rated to support CAT9’s increased bandwidth (

CAT9 vs. Other Cable Standards

CAT9 cables are designed to support significantly higher bandwidth and speeds compared to many other Ethernet cable standards like CAT6a and CAT7. Some key differences include:

  • CAT9 supports bandwidth up to 2,000 MHz, compared to CAT6a which supports up to 500 MHz and CAT7 which supports up to 600 MHz (1). This enables CAT9 to potentially deliver speeds up to 100 Gbps, whereas CAT6a and CAT7 top out at 10 Gbps.
  • CAT9 uses shielded twisted pair cabling, helping minimize interference and crosstalk issues. CAT6 and CAT6a can be either shielded or unshielded (2).
  • CAT9 connectors are not compatible with the RJ45 connectors used for CAT5, CAT6, etc. Special GG45 or TERA connectors are required (3).

The main downside of CAT9 is that it is a newer standard not yet widely adopted. Components and infrastructure support are still limited compared to CAT6a. However, for future-proofing networks to support emerging 100 Gbps speeds, CAT9 provides the best performance and capacity (4).

Overall, CAT9 represents the next evolution in Ethernet cabling, but CAT6a remains a more cost-effective option for most networks today still operating at 1-10 Gbps speeds.


Future Outlook

With network bandwidth demands continuing to rise, CAT9 cable is expected to see widespread adoption in the coming years. As 4K video streaming, augmented reality, virtual reality, and other high bandwidth applications become more common, the increased speed and throughput capacity of CAT9 will be required.

While CAT6 and even CAT7 cables are sufficient for most networks today, they may not be able to handle the demands of the future. CAT9, with its ability to support bandwidths up to 2,000MHz and speeds up to 100Gbps, will likely become the new standard for networks. This will allow it to meet the high data transfer rates expected for emerging technologies.

The cost of CAT9 is also expected to come down over time, making its higher performance more affordable for home and business users alike. Though still more expensive than CAT6 today, increasing economies of scale in production should lower prices to more closely match other standards. This will drive faster uptake once the need for its capabilities becomes more widespread.


CAT9 Connect Composite Cable is a high-speed networking cable with impressive bandwidth and performance capabilities that no other cable standard can match. Technology continues to advance and demand for fast, reliable connections is growing. For businesses, data centers, and other organizations that need to transfer enormous amounts of data quickly and efficiently, CAT9 offers a cutting-edge solution.

With its innovative construction using connect composite technology, CAT9 provides speeds up to 2,000 MHz and can support bandwidth up to 100 Gbps. The higher frequency allows for faster data transfer compared to older cable standards like CAT6 and CAT7. CAT9’s shielding and noise resistance also ensure a clean, stable signal even at extremely high speeds.

CAT9 should be considered for new construction projects, upgrades of aging infrastructure, and any application where future-proofing connectivity is a priority. As networks evolve to keep pace with emerging technologies like AI, IoT, 8K video, and more, CAT9 will be ready to handle tomorrow’s demands. For organizations that want to maximize performance and minimize latency, CAT9 is the clear choice over lesser standards.
