## Long description

The DIGITUS USB 3.2 Gen1 CAT Extender DA-73121 allows USB devices to be connected over distances up to 100 m using a CAT 6A (or higher) cable. It extends USB 3.2 Gen1 signals at data rates up to 5 Gbps and provides four downstream ports (three USB-A and one USB-C). The transmitter is powered via the host device and the receiver is DC powered, enabling remote placement of cameras, printers, hard drives, keyboards and other USB peripherals without the usual cable length limitations.
Advantages
This extender supports high transfer speeds up to 5 Gbps while maintaining compatibility with USB 2.0 and 1.1 devices. It combines a multifunctional four-port hub with Power-over-Cable functionality so only the receiver requires an external DC power supply. Integrated protection circuits provide ESD and overvoltage protection. The metal housing and compact dimensions ensure robust operation in office, conference or industrial environments. Installation is plug-and-play and requires no additional drivers.
Suitable for
Extending USB peripherals in large offices and conference rooms
Connecting remote surveillance cameras and security systems
Attaching printers, scanners and external hard drives at distance
Industrial workstations and production environments requiring durable connections
