Black Box ICU544A USB 3.1 Extender Over Fiber, 4-Port

Move USB 3.1 connectivity beyond the practical reach of copper and keep critical peripherals accessible where they are needed most. The Black Box ICU544A USB 3.1 Extender Over Fiber uses multimode fiber to carry USB connections across longer runs while supporting four ports for multiple attached devices. This design is well suited to controlled IT spaces where endpoint placement matters: secure equipment rooms, production floors, labs, kiosks, and remote workstations. By shifting the USB host connection away from the user area, it helps reduce cable clutter, improve physical layout, and preserve access to devices that must remain close to the operator. For teams standardizing on fiber infrastructure, this extender fits naturally into environments that already depend on structured cabling and rack-based deployment. The 4-port design gives you room for more than one peripheral without adding extra adapters at the edge. It is a practical choice when you need dependable USB extension with the cleaner signal path and installation flexibility that fiber provides.
