DeLOCK USB cable USB 3.2 Gen 2 10m USB C Black 84257

This DeLOCK USB cable (model 84257) with USB-C connectors on both ends is a 10 m active optical cable designed to connect a device with a USB Type-C™ connector to a PC or laptop with a free USB Type-C™ port. It supports DisplayPort Alternate Mode and USB 3.2 Gen 2 data transfer, and it is intended for long-distance, high-speed signal transmission.

Advantages

The active optical design uses optical fiber to transmit high-speed signals, making the cable thinner, lighter and more flexible than equivalent copper cables while allowing longer distance transmission without significant signal loss. It supports DisplayPort 2.1 with 4 lanes for high-resolution video, USB data transfer at up to 10 Gbps, and USB Power Delivery up to 60 W (20 V / 3 A). The cable has USB-C connectors on both ends and a 10 m length, suitable for installations requiring extended reach.

Suitable for

• Connecting a USB-C monitor (DisplayPort Alt Mode) to a computer up to 8K@60 Hz
• Video and data transmission between USB-C devices over long distances
• Connections where up to 60 W power delivery is required
• Setups needing USB 3.2 Gen 2 (10 Gbps) data throughput

How to use

Connect one USB-C connector to the computer or docking station that supports DisplayPort Alternate Mode and USB 3.2 Gen 2, and connect the other USB-C connector to the USB-C monitor or peripheral device. Ensure the host device supports DP Alt Mode for video output. When connecting USB 10 Gbps compatible devices, the cable will provide up to 10 Gbps data transfer rates; USB 2.0 devices are also supported at their native speeds. For power delivery, ensure the source supports USB PD and does not exceed the cable's 60 W (20 V / 3 A) capability.

Recommendations

Use this cable for DP Alt Mode connections only; do not expect compatibility with Thunderbolt™ ports. Avoid sharp bends and excessive mechanical stress on the cable and connectors to preserve the optical fiber integrity. For full video performance, verify both host and display support the stated DisplayPort version and lane configuration.
