Gefen Dual Link DVI (Dongle Modules)
Experience uncompromising image quality and flexible installation with Gefen Dual Link DVI Dongle Modules—modular fiber optic extenders that deliver pristine dual-link DVI signals over a long-distance fiber link. Featuring Virtual EDID and a two-strand multimode fiber pathway, these dongles are engineered for professional AV systems, digital signage, broadcast environments, and demanding control rooms where high-resolution displays must be fed without compression or signal degradation. By separating the transmitter and receiver into modular dongles, installers gain unprecedented flexibility to route DVI across distances up to 3300 feet (1 kilometer) while preserving the full 3840 x 2400 (WQXGA) resolution, color fidelity, and sharp text across the display chain. If you’re seeking scalable, maintenance-friendly DVI extension that meets the needs of high-end monitors, projectors, and medical imaging displays, Gefen’s Dual Link DVI fiber optic solution is a reliable choice that blends rugged construct with expert-grade performance.
- Modular dongle design: Separate transmitter and receiver modules allow flexible mounting, easy field servicing, and clean integration into equipment racks or wall installations.
- Long-distance dual-link DVI extension: Extends Dual Link DVI over a fiber path up to 3300 feet (1 kilometer) to reach distant displays without signal loss or compromise in image integrity.
- Virtual EDID for automatic compatibility: The Virtual EDID feature ensures that the source and display negotiate the correct timing, color space, and resolution, reducing setup time and display incompatibilities.
- High-resolution support: Capable of transmitting up to 3840 x 2400 (WQXGA) resolutions, preserving sharp text, vibrant color, and precise detail for professional applications.
- Structured fiber pathway using two-strand MMF: Utilizes 50/125 µm multimode fiber, providing a robust and interference-resistant link suitable for demanding environments while keeping the installation compact and clean.

how to install Gefen Dual Link DVI (Dongle Modules)
- Identify the transmitter and receiver dongles and connect the dual-link DVI source to the transmitter’s DVI input using a standard dual-link DVI cable, ensuring a secure and clean connection.
- Connect the display’s DVI input to the receiver dongle using a second dual-link DVI cable, verifying the cable quality and pin alignment to prevent signal issues.
- Link the two dongles with a two-strand multimode fiber cable (50/125 µm). Route the fiber path away from sharp bends, sources of heat, and potential interference sources to minimize attenuation and maintain signal integrity.
- Power the dongles per the manufacturer’s instructions, and confirm that the Virtual EDID feature is active so the source and display negotiate proper timing and resolution automatically.
- Power on the source and display, then test the full signal path. If necessary, adjust the EDID settings or display resolution to optimize performance for the connected monitor or projector.
Frequently asked questions
-
Q: What is the maximum distance I can run with Gefen Dual Link DVI Dongle Modules?
A: The system supports a distance of up to 3300 feet (approximately 1 kilometer) when using the specified two-strand multimode fiber (50/125 µm). This makes it ideal for long runs in corporate environments, auditoriums, and control rooms without sacrificing image quality.
-
Q: What resolutions are supported by this extender?
A: The modules are designed to deliver Dual Link DVI at resolutions up to 3840 x 2400 (WQXGA), ensuring crisp text, detailed imagery, and accurate color reproduction for high-end displays and professional-grade projectors.
-
Q: What role does Virtual EDID play in the setup?
A: Virtual EDID enables automatic negotiation of timing and resolution between the DVI source and the display, reducing setup complexity and avoiding common compatibility issues that can occur with manual EDID management.
-
Q: Do I need software to operate the Gefen Dual Link DVI Dongle Modules?
A: No software installation is required. The system is hardware-based and relies on standard DVI signaling and Virtual EDID to establish the connection. Some installations may benefit from documentation for cabling and EDID configuration, but no software is necessary.
-
Q: Can I use standard multimode fiber or do I need a special fiber type?
A: The recommended fiber type is a two-strand multimode fiber with 50/125 µm core/cladding. This fiber type provides reliable transmission for dual-link DVI at the specified distances and resolutions, while remaining relatively easy to install and terminate in most environments.
