Product information

Description

The DIGITUS DA-73121 USB 3.2 Gen1 CAT Extender allows connecting USB peripherals over a distance up to 100 meters using a network cable. It supports a data transfer rate of 5 Gbps and features four output ports including three USB-A ports and one USB-C port. This device overcomes traditional cable length limitations, enabling reliable connection of multiple USB devices in spaces where the host computer is located far away.

Advantages

The extender maintains high-speed data transmission up to 5 Gbps over long distances using a standard CAT network cable. It includes an integrated receiver amplifier that reduces signal loss and features built-in electrostatic discharge, overvoltage, and short-circuit protection for connected hardware. The metal housing ensures durability and physical stability in demanding environments. The system supports simultaneous operation of up to four peripherals through its mixed USB-A and USB-C port configuration. Installation is straightforward with Plug and Play functionality, requiring no additional drivers or software setup.

Suitable for

  • Connecting remote security cameras over long cable runs
  • Operating printers and scanners located in a different room
  • Extending keyboard and mouse connections for presentation setups
  • Setting up industrial control systems with distant peripheral devices

When it may not be suitable

This device is not designed for extending video display signals directly unless the connected peripheral is a USB video capture device. It requires a suitable CAT network cable of category 6A or higher, which is not included in the standard delivery scope.

Key specifications

  • Maximum range: 100 meters via CAT cable
  • Data transfer rate: Up to 5 Gbps
  • Output ports: 3x USB-A and 1x USB-C
  • Power consumption: Maximum 3.5 W
  • Housing material: Metal and aluminium
  • Dimensions: 76 mm width, 85 mm depth, 25 mm height

How to use

Connect the transmitter unit to the host computer using the provided USB cable. Link the transmitter and receiver units using a CAT 6A or higher network cable up to 100 meters in length. Connect the external power supply to the receiver unit, then plug your USB peripherals into the available USB-A and USB-C ports on the receiver. The system initializes automatically without requiring software installation.

What to consider before purchase

  • Verify that you have a compatible CAT 6A or higher network cable of the required length
  • Check the power availability near the receiver unit for the DC power supply
  • Confirm that your peripherals match the USB 3.2 Gen1 interface capabilities

Ensure that the network cable connecting the transmitter and receiver is routed away from high-voltage electrical lines to prevent potential electromagnetic interference and maintain stable data transfer performance.
