USB-C to USB-C Coaxial Cable DELOCK USB4 Gen 3x2 40 Gbps USB PD 3.1 240 W 1 m

The Delock USB-C to USB-C coaxial cable supports USB4 Gen 3x2 with data transfer rates up to 40 Gbps and USB Power Delivery 3.1 for supplying devices with up to 240 W. This one-metre black cable with gold-plated contacts carries USB, DisplayPort and PCI Express signals over a USB Type-C or Thunderbolt 3 port, allowing connection between compatible laptops, docking stations, external enclosures, monitors and chargers.

Advantages

The cable provides very high data bandwidth (up to 40 Gbps), multi-protocol support including DisplayPort Alternate Mode and PCI Express, and high-power charging up to 240 W via USB PD 3.1. Its coaxial construction and gold-plated contacts are designed to maintain signal integrity for demanding data and video applications.

Suitable for

• High-speed data transfer between compatible laptops, external enclosures and docks
• Connecting DisplayPort monitors using Alternate Mode, including up to 8K @ 30 Hz
• High-power charging of laptops and devices that support USB PD 3.1 up to 240 W

When it may not be suitable

This cable requires devices and hosts that support USB4 Gen 3x2 or compatible Alternate Modes to reach the maximum data rates and video capabilities; when used with older USB standards the transfer speeds will be limited to the capabilities of those devices. It also depends on the connected devices’ USB PD implementation for safe delivery of high power; if either end does not support USB PD 3.1 Extended Power Range, the power will be negotiated at a lower level.

Key specifications

• Connector type: USB-C to USB-C
• USB standard: USB4 Gen 3x2 (40 Gbps)
• Alternate modes: DisplayPort 1.4a and DisplayPort 2.0 Alternate Mode
• Maximum video: up to 8K @ 30 Hz via DisplayPort Alternate Mode
• Power delivery: USB PD 3.1 Extended Power Range, up to 240 W (48 V / 5 A)
• Cable length: 1 m
• Colour: Black

How to use

Connect one USB-C plug to a compatible host or charger and the other USB-C plug to the target device such as a laptop, dock or monitor. If both ends support USB4 Gen 3x2, the cable negotiates the highest data bandwidth automatically; when connecting a DisplayPort-capable device, video output is carried via DisplayPort Alternate Mode. For power delivery, ensure the power source and the target device support USB PD 3.1 Extended Power Range to achieve up to 240 W; power negotiation is handled by the devices over the cable.

What to consider before purchase

• Ensure both host and device support USB4 Gen 3x2 or the required Alternate Modes for full performance
• Confirm that both ends support USB PD 3.1 Extended Power Range if you need up to 240 W charging
• Check your monitor’s supported DisplayPort version and maximum resolution/refresh rate

Recommendations

Use the cable with devices and chargers that explicitly list USB4 Gen 3x2 and USB PD 3.1 (EPR) support to achieve full data, video and power performance; when connecting high-resolution monitors or performing heavy data transfers, avoid unnecessary cable bends and keep connections secure for best signal stability.
