Active Optical Cable Connects Servers, Hard Drives and Other USB-C Components
This USB 3.2 Gen 2 fiber optic cable (M/M) securely connects the USB-A port on your desktop, laptop or notebook computer to a USB-C device, such as a server, external hard drive or surveillance camera, located up to 20 meters (66 feet) away. This data-only cable supports USB 3.2 Gen 2 data transfer rates up to 10 Gbps. Note: This USB cable is not backward compatible with USB 3.2 Gen 1, 2.0 or 1.1 devices. 

Advanced Fiber Cable Is Easier to Install than Copper
Because the fiber cable is slimmer and more flexible than standard copper USB cables, the U428F-20M-D3 is easier to install around corners and in hard-to-reach spaces behind equipment. It draws power from the connected device, so no external power supply is needed to transmit the USB signal across the longer distances unique to fiber optic cabling. Note: The cable must be installed in the correct direction to function properly, so please check the Host and Device labels on the connectors before installation.

CMP Jacket Designed for In-Wall Installations
The plenum-rated jacket has low smoke and flame characteristics, making it suitable for premise applications in ceilings, walls and ducts.

20 m Cable Lets You Design an Application to Your Custom Specifications
This long cable allows you greater flexibility in placing your USB components. For instance, your camera or hard drive may be located in a different room away from your office or in a central location where others have access to it. The plug-and-play U428F-20M-D3 supports all major operating systems, including Windows, macOS and Linux. Note: If your device is not detected by the source, external power is needed for the device to receive and transmit data to the source.

System Requirements

  • USB 3.2 Gen 2 ports required on both connected devices. This cable is not compatible with previous USB generations.
  • Host device with a USB-A Port
  • Device with a USB-C Port
