USB-C cable DELOCK 84090 — 5 m, USB-C to USB-C, up to 21600 Mbit/s, gold-plated contacts, black

DELOCK 84090 is a 5 m USB-C to USB-C cable designed for reliable data transfer and extended connectivity between USB-C devices. The cable supports up to 21600 Mbit/s data throughput and features gold-plated connector contacts to reduce corrosion and improve signal contact. Its black jacket and slim design make it suitable for installations that require a longer reach while maintaining a tidy appearance. This active optical cable supports DisplayPort alternate mode for connecting compatible USB-C hosts to USB-C monitors with resolutions up to 4K Ultra HD (3840 x 2160 @ 60 Hz). Note that the cable is compatible only with DisplayPort (DP alt mode) devices and is not compatible with Thunderbolt devices.

Advantages

The cable combines a 5 m reach with high data throughput up to 21600 Mbit/s, allowing transmission over longer distances without signal loss thanks to its active optical construction. Gold-plated contacts provide improved contact reliability and resistance to corrosion. The slim, black design facilitates tidy cable routing and integration with desktop setups, docking stations and AV installations that require a clean appearance and extended physical separation between devices.

Suitable for

• Connecting a USB-C™ computer to a USB-C™ monitor using DisplayPort alternate mode (up to 4K @ 60 Hz)
• Linking laptops to docking stations or hubs that support DP alt mode
• Connecting external drives and peripherals where a 5 m cable run is needed for workspace layout
• AV setups and presentations that require a longer cable length without active signal degradation

Key specifications

• Cable length: 5 m
• Connector type: USB-C to USB-C
• Maximum data transfer rate: up to 21600 Mbit/s
• Gold-plated connector contacts for improved corrosion resistance
• Active optical cable design for long-distance signal transmission
• Color: black
• Supports DisplayPort alternate mode for video transmission up to 4K Ultra HD (3840 x 2160 @ 60 Hz)

How to use

Connect one USB-C connector to a host device (for example, a laptop or docking station) that supports DisplayPort alternate mode, and plug the other USB-C connector into a compatible USB-C monitor or display. Ensure both devices advertise DP alt mode support before use. The active optical design requires no user configuration; once connected, the devices should negotiate video and data transfer automatically. If video does not appear, verify monitor input selection and host display settings.

Recommendations

Use this cable only with devices that support DisplayPort (DP alt mode). Do not use it with Thunderbolt devices, as compatibility is not guaranteed. Avoid tight bends near the connectors and secure cable routing to prevent stress on the connectors. For optimal video performance at 4K @ 60 Hz, ensure both host and display firmware/drivers are up to date.
