Cable Matters 40Gbps USB4 Extension Cable, USB4 Male to Female, 1.6ft /0.5m | [8K@60Hz / 4K@240Hz, 240W Charging, 40Gbps Data Transfer] True Reversible Design, USB C Extender, USB 4 Extension Cable

It is working as expected. I connect usb c hub to it. Only issue is manufacturing year was 2014.

I would say, i am aure this is costly, but you are getting what you are paying for. Seriously, the cable quality is so good. This functions extremely well. I have a doc which is connected to a 4k 60 fps monitor to it , along with a 1Gig LAN , a keyboard, and a storage device & a 100watt charger. That doc is having a very small cable. My main moto was to buy this cable to make sure i can extend the doc cable. This is exactly doing the same. No quality or speed drop found so far. I am happy with my purchase.

If you’re looking to extend the reach of a USB4 or Thunderbolt 4 device without sacrificing performance, the Cable Matters 40Gbps USB4 Extension Cable is an excellent option to consider. Its robust build, short length, and compliance with high-end specs make it a reliable choice for demanding setups—whether you’re connecting 8K displays, external SSDs, or high-powered docking stations. Key Features 40Gbps USB4 / Thunderbolt 4 Speed Officially rated for up to 40Gbps data throughput, meaning you can transfer large files quickly and maintain the full speed of external SSDs or other high-bandwidth peripherals. Backward compatible with Thunderbolt 3, USB-C 3.x, and USB 2.0 devices, so it works well even with older gear. High-Resolution Video Support Supports 8K@60Hz or 4K@240Hz, making it a solid pick for cutting-edge displays or high refresh rate monitors. Ideal for content creators, gamers, or professionals needing top-tier resolution and fluid motion. Compact 1.6-Foot Length Short, tidy extension for tight spaces or cable management. Minimizes potential signal degradation that can occur with longer cables, helping ensure maximum performance. Perfect for bridging a small gap between a desktop port and a device without excessive cable clutter. Durable Construction Cable Matters has a solid reputation for producing sturdy cables, and this one is no exception. Reinforced connectors and a thick cable jacket provide extra protection against daily wear and tear. Performance & Reliability Stable Connection: During testing with a Thunderbolt 4 dock and an 8K monitor, the extended cable maintained consistent data rates and video signals. There was no flickering, stuttering, or unexpected disconnects. Broad Device Compatibility: Plugging in various devices—like external SSDs, VR headsets, and high-powered docking stations—worked smoothly. In each case, the cable extension retained full functionality and speed. Minimal Latency: Even with resource-intensive tasks (like video editing off an external SSD), latency stayed effectively negligible. Users who rely on real-time data (such as audio engineers or gamers) shouldn’t notice any performance hit. Use Cases High-Resolution Monitors: If you need a little extra reach between your PC/Mac and an 8K or 4K display—especially with high refresh rates—this extension cable maintains the full bandwidth for crisp visuals. External SSD Enclosures: For large data transfers or on-the-go editing, the extension ensures you’re not losing speed if the built-in cable is too short to reach your workstation comfortably. Thunderbolt/USB4 Docking Stations: Extend that short built-in cable on your dock without hindering its full range of ports and performance. VR/AR Headsets: Keeping your VR headset cord at an optimal length is much easier with a short extension that can handle high data rates. Pros & Cons Pros Full 40Gbps Speed – Zero noticeable drop in performance for data-heavy tasks. 8K@60Hz or 4K@240Hz Support – Great for ultra-high-definition setups. Robust Build Quality – Reinforced connectors and thick cable jacket for longevity. Short, Manageable Length – Ideal for close-range devices or tight desk spaces. Cons Limited Length – At only 1.6ft (about half a meter), it’s specifically designed as a short extension; if you need more reach, you’ll need a different solution or multiple cables. Premium Price – USB4/Thunderbolt 4 cables can be pricier due to stringent certification and higher specs, which might be overkill if you only need basic USB-C speeds. Final Thoughts For anyone needing to extend a USB4 or Thunderbolt 4 connection without losing any of the top-tier features—like 40Gbps transfers, 8K video output, or robust power delivery—the Cable Matters 40Gbps USB4 Extension Cable (1.6ft) is a compelling choice. It’s well-made, reliable, and ensures your high-end devices and peripherals operate at full speed. If you have a tight setup where every inch matters and want to maintain maximum performance, this short extension cable is highly recommended.

Cable works with Nintendo Switch 2 dock. See photo reflection on Swich 2. No overheating issues with the Switch 2 so far. Brought cable as kids were quite harsh docking and undocking. You will need to push down the usb c shield inside the dock to expose the male part of the usb c connection. Then while holding down the shield line up the female end of the usb c cable and push it on. After this connect the usb c male connection into the Switch 2. Definitely recommend this, buy it!

Works well, does the job.
