The Gefen EXT-DVI-3500HD allows you to operate a single DVI-compliant computer at two physical locations. DVI, USB, analog audio, and RS-232 are extended from the local computer to the remote workstation. USB peripherals can be operated by the computer at either location exclusively.

How It Works
Gefen's EXT-DVI-3500HD system consists of a Sender and a Receiver unit. The Sender connects to the computer's DVI-compliant video card output, analog audio jack, RS-232 port, and USB port. The EXT-DVI-3500HD Receiver connects to the remote display and peripherals. Four strands of LC fiber optic cable connect the Sender and Receiver together.

The EXT-DVI-3500HD has two modes of USB operation. When in local mode, the computer sees USB devices connected to the Sender. When in remote mode, the computer sees USB devices connected to the Receiver. Modes are switched using a switch on the front panel of the Sender.

Extension distance will depend on the type of fiber media used:

Single Mode: WUXGA resolution @ 2000m (6,600ft)
Multi-Mode : WUXGA resolution @ 500m (1,650ft)
