DIGITUS USB Extender, USB 3.2 Gen1, 100m 3x USB-A & 1x USB-C, For use with CAT cable

Features

The DA-73121 extender uses HDBaseT-like transmission to overcome standard USB cable limitations and allows peripheral placement up to 100 m from the computer. The transmitter connects via USB-C to the host system, while the receiver provides four independent USB 3.2 Gen1 ports (3×A + 1×C).

Transmitter power is drawn from the host, eliminating the need for an extra power cable at the source side. The receiver is powered by the included 12 V adapter, with sufficient capacity to supply connected devices via PoC (Power over Cable).

A built-in signal amplifier on the receiver side compensates for losses over long distances, maintaining stable performance at the full 5 Gbps speed. Protection against ESD, overvoltage, lightning, and short circuits safeguards both the extender and attached peripherals.
