USB4 40 Gbps cable for high-speed workflows

This 1.5 ft USB4 cable delivers up to 40 Gbps bi-directional bandwidth with USB4 Gen 3x2 devices. It also supports 8K video output and Thunderbolt 3/4 compatibility. The integrated E-Marker chip ensures reliable communication between host and peripheral. It suits creative professionals moving large media files between SSD enclosures, docks and laptops.

Simple plug-in with E-Marker assurance

The reversible USB-C connectors insert either way up for quick, bi-directional connection. An embedded E-Marker chip negotiates power and data rates automatically, reducing handshake errors. The braided jacket resists tangling during frequent connect-disconnect cycles. Users should verify that both host and device support USB4 or Thunderbolt to reach the 40 Gbps ceiling.

Check host and charger capabilities first

Confirm your laptop, dock or hub lists USB4 Gen 3x2 or Thunderbolt 3/4 on its USB-C ports. For 240 W charging you need a PD 3.1 EPR charger rated at 48 V and a device that accepts Extended Power Range. The cable is backwards compatible with 180 W, 140 W, 100 W and 60 W profiles. Without matching hardware the link will fall back to lower speeds and power levels.

Questions about this item

How can I confirm the cable is delivering 40 Gbps after connecting it?

The cable carries an E-Marker chip; when linked between two USB4 Gen 3x2 ports the OS negotiates 40 Gbps automatically and you can verify the link speed in the system information or Thunderbolt control panel.

What comes in the package and is a charger included?

Only the 1.5 ft USB-C to USB-C braided cable is supplied; a 240 W PD 3.1 charger and a device that accepts 240 W must be purchased separately to reach the maximum power rating.

Should I choose the 1.5 ft or the 5 ft version for a desktop SSD dock?

The 1.5 ft length keeps signal integrity highest for 40 Gbps and 240 W, so it is the better choice when the dock sits right next to the host; pick the longer cable only if the extra reach is essential.
