This article covers Cable Matters 80Gbps USB4 延長ケーブル 0.5m.

Overview

The Cable Matters 80Gbps USB4 Extension Cable 0.5m is a high-performance USB-C male-to-female extension cable that supports full USB4 Gen4 bandwidth (80Gbps), up to 240W Power Delivery 3.1 EPR, and video output up to 8K@120Hz or 4K@480Hz. It is designed to extend your existing USB-C or Thunderbolt cable by 0.5 meters, making it ideal for tidying up desk setups or reaching ports on the back of a dock. This cable is fully backward compatible with Thunderbolt 4/5 and USB 3.2, and works with the Nintendo Switch 2 as well.

Connectivity & Compatibility

The extension cable uses a reversible USB-C male-to-female connector and supports USB4 V2.0, USB4 Gen4, Thunderbolt 5, Thunderbolt 4, USB 3.2 Gen2×2, and earlier standards. It is especially useful for bringing rear ports on docking stations or hubs closer to your workspace. For full 240W charging, both the charger and the device must support USB PD 3.1 EPR. The cable works with any standard USB-C device including laptops, tablets, smartphones, and game consoles.

Product Info

Expected release: late 2025. Price: approximately ¥1,519 on major online retailers. Standard 1-year warranty from Cable Matters. The package includes only the cable; no extra adapters or pouches. Market positioning: high-end extension cable that combines the fastest available data rate (80Gbps) with the highest available power delivery (240W) in a 0.5m form factor. Compared to typical 40Gbps cables at similar prices, this cable offers double the bandwidth and double the charging capacity, making it a future-proof choice for cutting-edge hardware.

Best Use Cases

  • Owners of Thunderbolt 5 laptops (e.g., MacBook Pro, Intel Core Ultra series): If you want to fully utilize the 80Gbps bandwidth of Thunderbolt 5, this extension cable ensures you don't lose speed when extending your connection. It also provides enough power headroom for large laptops. However, if your devices only support Thunderbolt 4 (40Gbps), the cable's extra bandwidth is unnecessary. - Creative professionals using 8K monitors or 4K high-refresh-rate displays: Video editors, 3D artists, and gamers who need 8K@120Hz or 4K@480Hz output will benefit from the cable's full bandwidth retention. The 240W PD support also allows simultaneous charging of a power-hungry laptop, reducing cable clutter. - Gamers with Nintendo Switch 2: The cable works with Switch 2 for charging, data transfer, and potentially video output. Even though Switch 2's maximum charging rate is lower (around 65W), having a high-spec cable ensures reliability and future compatibility.
