Features
USB4 Cable Streams Video and Processes Data at 40 Gbps, 8x Faster Than USB 3.0
This USB4 40Gbps cable (M/M) transmits across two bidirectional lanes, supporting speeds up to 40 Gbps, which is eight times faster than USB 3.0/3.1/3.2. Unlike previous USB generations, the USB4 40Gbps cable has the ability to allocate resources. Instead of splitting video and data equally between its two lanes, the U521-1P2M-BK allows the connected display as much bandwidth as it needs, while saving all remaining bandwidth for high-speed data transfers. This makes the cable perfectly suited for 4K or 8K video streaming and editing, as well as transferring large RAW video or CAD files.
Supports DisplayPort Alternate Mode for Unidirectional 80 Gbps Video Connections
By connecting a 4K or 8K display to a host device that supports DisplayPort Alt Mode 2.1, this cable can use both high-speed lanes to transmit 4K or even 8K video at 60 Hz in one direction at 80 Gbps maximum speed with 30-bit Deep Color, HDR and 4:4:4 chroma subsampling. Connected to a host that supports DisplayPort Alt Mode 1.4, the U521-1P2M-BK can transmit 8K at 30 Hz.
Backward Compatible with Legacy USB and Thunderbolt 3 Devices
Though both connected devices must support USB4 40Gbps for the cable to reach its full potential, the U521-1P2M-BK is backward compatible with USB 3.x, USB 2.0 and Thunderbolt 3 devices. It connects two USB-C devices, including MacBooks, Chromebooks, Windows laptops, Kindles, game consoles, smartphones, external hard drives, docking stations and wall chargers. It is compatible with all USB-C and Thunderbolt 3 devices, enabling use in existing installations while preparing for future upgrades.
PD Charging Cable Keeps the Connected Notebook, Laptop or Other Device at Capacity
The U521-1P2M-BK supports Power Delivery (PD) 3.1 charging of the connected PD Charging-compliant device. It carries power output up to 48V 5A (240W), which is sufficient for fast-charging and powering your MacBook or other mobile device, including the latest iPhone and other smartphones with a USB-C connector.
USB-IF Certification Ensures Rigorous Testing and Top-of-the-Line Performance
This cable meets the high standards of USB-IF (USB Implementers Forum, Inc.), a non-profit organization consisting of companies that developed the USB specification. Receiving USB-IF certification means the U521-1P2M-BK meets the industry’s highest environmental, mechanical and electrical standards. It operates with your USB peripherals, adapters and cables with top efficiency and safety.
System Requirements
- Devices with USB-C or Thunderbolt 3 ports (USB4 40Gbps compatibility required to achieve USB4 40Gbps performance)
- DP 2.1 Alt Mode required for maximum video output capability (8K/60Hz)
- 240W PD Charging output is supported, but the actual charging performance of a connected device is dictated by the maximum power draw of the device itself
