1.5 ft USB4 cable for 40 Gbps workflows

This 1.5 ft USB4 cable connects two USB-C devices at up to 40 Gbps and carries up to 240 W of Power Delivery 3.1. It is USB-IF certified and includes an E-marker for reliable negotiation. The white jacket and 24 AWG conductors suit desk or travel use where a short, high-speed link is needed.

Practical limits of 40 Gbps USB4 at this length

At 1.5 ft the cable supports the full 40 Gbps rate and DisplayPort 2.1 video up to 8K 60 Hz or 4K 240 Hz. Longer cables would drop to 20 Gbps, so this length is chosen to keep maximum throughput. Thunderbolt 3 hosts are also supported, but the cable cannot exceed its rated 40 Gbps or 240 W under any condition.

Plug in and work; watch for port alignment

Installation is a simple USB-C to USB-C insertion on each end with no driver required. The reversible connectors prevent upside-down attempts. The only common issue is forcing a connector into a damaged or debris-filled port, which can bend pins; inspect both ports before connecting.

Questions about this item

Should I pick the 1.5 ft length or a longer cable for my setup?

The 1.5 ft (45 cm) length keeps signal loss minimal for 40 Gbps USB4 and 240 W PD 3.1, making it ideal for desk docking; choose a longer cable only if the extra reach is essential.

What does the 40 Gbps rating actually deliver when I plug this into my laptop?

It provides up to 40 Gbit/s USB4 data throughput, supports DisplayPort 2.1 with DSC for 8K 60 Hz or 4K 240 Hz video, and carries Thunderbolt 3 traffic at full speed.

How does the USB-C connector and E-marker firmware limit what I can connect?

The USB-C to USB-C plug with E-marker firmware enables USB4 40 Gbps, Thunderbolt 3, and 240 W EPR power delivery, so any USB-C port negotiates the highest common speed and power.
