USB4 80Gbps cable for high-bandwidth workflows

This USB-C to USB-C cable delivers USB-IF certified USB4 80Gbps data transfer, DisplayPort 2.1 Alt Mode video up to 8K 120Hz or dual 4K 120Hz, and 240W Power Delivery 3.1 charging. It is built for professionals moving large datasets or driving high-resolution displays from a single port.

Replaces slower USB-C cables that limit throughput

The jump is worth it when your host, dock or monitor supports USB4 80Gbps and you need full 240W EPR charging alongside uncompressed 8K video. Cables rated for 40Gbps or lower PD wattages will bottleneck both bandwidth and charging speed in this scenario.

Maintains certified 80Gbps signal integrity over

Shielded 30/34 AWG coaxial construction with an E-marker chip and laser-etched USB4 markings ensures stable performance during long file moves or continuous 8K streaming. Thunderbolt 4 compatible operation remains consistent without thermal throttling or signal degradation.

Questions about this item

What clearance does the 45 cm USB-C to USB-C cable need for routing?

The 1.5 ft length fits tight laptop-to-dock runs; the 30/34 AWG coaxial construction bends cleanly behind monitors without kinking.

Which orientation do the laser-etched USB4 markings face when plugging in?

Both ends are male USB-C with identical laser-etched USB4 spec markings; the reversible connector inserts either way up and the certified E-marker firmware negotiates 80 Gbps automatically.

When should the cable be replaced if 240 W PD 3.1 charging is used daily?

The USB-IF certified assembly with shielded EMI protection and lifetime warranty is rated for continuous 240 W EPR PD 3.1; inspect connectors for debris or bent pins after heavy use cycles.
