The CrystalLink USB1.1 dual-port is a versatile extender device that can be used in multiple different applications. It is a great way to put your peripherals where they are convenient to the user or to secure the USB host from unwanted access.

The CrystalLink USB1.1 extends up to 130 feet (40 meters) over CATx UTP/STP cable. Individual USB devices such as a Keyboard or Mouse, USB thumb-drive, USB Printer and USB Joystick can be extended away from the host PC using the CrystalLink USB1.1 extender. Additional USB devices can be connected using a powered USB hub. The CATx extension cable can be CAT5e, 6 or 7, UTP/STP cable. Extension performance is optimized with the use of CATx solid core cable. Stranded (patch) cable and the use of patch panels will reduce the maximum operational distance. STP cable with grounded metal hoods is recommended.

No external power is required to operate this device.
