Extend DVI-D and USB-HID up to 6.2 Miles over single-mode fiber Connect a monitor, keyboard, and mouse to the computer and have a KVM console on the remote end. Use your computer at either location! Our ServSwitch Single DVI Fiber Optic KVM Extender for USB enables you to send keyboard, mouse, and DVI-D video signals at up to 6.2 miles (10 km) over single-mode fiber. This extender works with a USB keyboard and mouse over fiber. Connect a keyboard, mouse, and DVI-D monitor directly to the computer on the transmitting end of the link and a KVM console with a DVI-D monitor on the receiving end. This method of dual access enables you to use your computer at either location. With more monitors connected to your computer, you can put a different application on each monitor. And if you have an application that uses lots of small windows, you can expand it across both monitors to provide more work space. Now that's versatility!
