Gefen USB 2.0 SR Extender over one CAT-5 Cable


Extend USB 2.0 up to 50 meters/165 feet, over a single CAT-5

Gefen’s EXT-USB2.0-SR extends high-speed USB devices over a single CAT-5e cable, up to 50 meters/165 feet.

It works with all major operating systems -- Windows, macOS and Linux. No software drivers are required.

The Sender and Receiver units install in minutes without any configuration, and support USB versions 2.0 and 1.1 - essential for high-performance applications such as digital imaging and interactive gaming.

The full-size Type-A USB connector on the Receiver unit can supply up to 2 Amps of current at 5V, ensuring sufficient power for practically any USB device.

Sender and Receiver are compact in size, easy to install, and can be hidden away. Their sturdy metal enclosures ensure best possible performance by providing insulation against electromagnetic interference from other devices nearby.

The Gefen USB 2.0 Extender is ideal for remotely accessing laser printers, scanners, external hard drives, optical disc burners, flash drives, and standard resolution web cams.

A powered USB hub may be connected to the USB 2.0 SR Receiver to allow for the connection of additional USB devices.

Applications such as Remote Desktop (keyboard/mouse/touchscreen), security, industrial control, digital signage control, and scientific data acquisition are all made possible thanks to EXT-USB2.0-SR’s universal implementation of USB standards.

Using a USB hub at the output of the EXT-USB2.0-SR would reduce the extension range to approximately 40 meters/132 feet. The exact range reduction would depend on the USB hub design. Some hubs may perform better than others.
