The UE2120H allows users to extend the distance between a computer and USB device(s) up to 40 feet (12 m) via the active extender hub. USB signals transmitted through these cables maintain optimal signal integrity and meet USB 2.0 standards. Up to 4 extender cables (UE2120) and 1 Extender Hub (UE2120H) can be chained together, so that cable distance is increased by up to 200 feet (60 m).
