The PureLink FI-U400-003 USB4 Gen2x2 0.3 m cable is a USB-C to USB-C cable engineered for professional AV and high-speed data tasks. It supports USB4 Gen 2x2 transfer rates up to 20 Gbit/s, USB Power Delivery up to 100 W and DP Alt Mode for video output up to 8K@30Hz. The cable has a compact, ultra-flexible Ø 5.0 mm construction with high-purity copper conductors and graphene nano shielding, and comes in black and blue.

Advantages

The cable combines high data throughput and reliable power delivery in a compact form factor suitable for tight installations. E‑Marker support ensures correct power negotiation and safe charging up to 100 W. Graphene nano shielding and quality copper conductors reduce interference and preserve signal integrity during high-bandwidth transfers.

How to use

Connect one USB-C end to a USB4-compatible host or source and the other USB-C end to the target device (laptop, monitor, dock or peripheral). Ensure both connected devices support the required USB4, Power Delivery or DP Alt Mode features for full functionality. For charging, verify the source provides sufficient PD wattage and that the cable's E‑Marker is recognised by the devices.

Recommendations

Use the cable in indoor environments and avoid sharp bends beyond the cable's flex radius; route the cable away from strong electromagnetic sources to maintain optimal signal integrity. For high-resolution video or maximum power delivery, confirm device compatibility with USB4 Gen 2x2 and PD standards.
