Gefen EXT-DVI-FM1000 Video Console/Extender

The Gefen EXT-DVI-FM1000 Video Console/Extender is a premium solution for distributing DVI video over long distances with flawless fidelity. Built for professional AV applications—from corporate boardrooms to digital signage and control rooms—it delivers crystal-clear DVI imagery up to 3,280 feet away from the source. By employing a 100% optical SC fiber link on a single strand, this system eliminates electrical interference and signal loss that plague copper runs, ensuring stable performance in busy environments. With just two compact transceivers, installation remains tidy and unobtrusive, while automatic EDID programming guarantees fast, reliable synchronization between source and display, even in complex room configurations or multi-display deployments.

• Long-range DVI over fiber: Extend your DVI display up to 3,280 feet (1,000 meters) from the video source, enabling flexible placement of displays in large rooms, auditoriums, classrooms, or venues where the source and display cannot be co-located. The optical link maintains image integrity, color accuracy, and sharp detail across the entire distance, delivering a consistent viewing experience for presentations, signage, or command-center dashboards.
• Two compact transceivers for simple setups: The EXT-DVI-FM1000 uses only two small transceivers—one at the source and one at the display end—minimizing clutter behind equipment racks or podiums. This streamlined hardware footprint makes it easy to install in tight spaces, behind walls, or within standard AV rack cabinets, while still delivering robust, professional-grade performance.
• 100% optical SC fiber solution on a single strand: The system relies on a single strand of SC fiber fiber optic cable to carry the entire DVI signal. This design delivers excellent immunity to EMI, grounding issues, and environmental noise, reducing downtime and maintenance while allowing routing paths that are impractical for copper cables.
• Automatic EDID programming for reliable synchronization: The EXT-DVI-FM1000 automatically negotiates the EDID with the connected display, ensuring the correct resolution, refresh rate, and timing. This minimizes setup time, prevents mismatched displays, and helps preserve consistent image quality when switching between sources or when new displays are introduced into the system.
• Designed for professional DVI deployments: Optimized for DVI video signals, the extender preserves pixel integrity and color fidelity across the link. It is an ideal choice for environments that require high-quality, long-distance DVI transmission without converting to other formats, ensuring compatibility with standard DVI sources and displays and delivering dependable performance in room-scale AV installations, training facilities, and public-facing displays.

How to install Gefen EXT-DVI-FM1000

1. Identify the source device with the DVI output and the display device with the DVI input. Ensure both devices are powered off before connecting.

2. Connect the transmitter unit to the video source using a standard DVI cable, ensuring a solid, secure connection at the DVI output of the source.

3. Connect the receiver unit to the display using another DVI cable, firmly seating the cable in both the display input and the receiver’s output.

4. Run a single strand of SC fiber optic cable between the transmitter and receiver. Carefully route the fiber to avoid sharp bends or tension, and secure it as required by the installation environment.

5. Power on the transmitter and receiver units. Allow a moment for the system to initialize and for the EDID to negotiate between the source and display. The display should begin showing the source output once synchronization completes.

Frequently asked questions

• Q: What is the maximum extension distance?

  A: The EXT-DVI-FM1000 extends DVI displays up to 3,280 ft (1,000 meters) from the video source using a single strand of SC fiber.

• Q: Does this device convert DVI to HDMI or vice versa?

  A: No. The EXT-DVI-FM1000 is designed specifically for DVI signals and does not convert to HDMI. Use with DVI sources and displays only.

• Q: How many transceivers are required?

  A: Two transceivers are required—one at the video source (transmitter) and one at the display (receiver).

• Q: What type of fiber is used?

  A: A single strand of SC fiber optic cable is used for the optical link, offering high bandwidth and excellent noise immunity.

• Q: What resolutions are supported?

  A: The extender preserves standard DVI video formats supported by the source and display. Exact supported resolutions depend on the capabilities of your specific DVI source and display devices; EDID is automatically negotiated for reliable timing.

• Q: Is EDID automatically managed?

  A: Yes. The EXT-DVI-FM1000 automatically programs EDID to ensure quick and correct synchronization between source and display.
