USB4 cable for Thunderbolt 4 and USB-C

The Silkland cable carries data at 40Gbps, delivers up to 240W of power and drives an 8K display at 60Hz. It uses a male-to-male USB-C connector pair and is USB-IF certified. The 3.3FT length suits desktop setups where the host and peripheral sit close together.

Replaces slower USB-C cables that limit charging

If your current cable tops out at 100W or cannot drive 8K, this one removes both bottlenecks in a single wire. The jump is worth it when you need full Thunderbolt 4 bandwidth, 240W PD 3.1 charging and high-resolution video simultaneously.

Practical limits of the USB4 interface

Copper construction caps reliable performance at short lengths; the maker recommends staying below 5FT for stable docking-station operation. Actual throughput still depends on the host and device supporting the same 40Gbps rate. The cable is backward compatible with earlier USB speeds.

Questions about this item

What length is the 3.3FT USB4 cable and what connectors does it use?

The cable measures 3.3FT and has male-to-male USB-C connectors on both ends.

How do I install the cable so the E-Marker chip negotiates 240W charging correctly?

Connect the cable to a PD3.1 charger and a device that supports 48V/5A; the E-Marker chip then negotiates the full 240W automatically.

When should I replace the cable if the braided jacket shows wear?

Replace the cable if the nylon braid frays enough to expose the copper conductors or if connectors become loose.
