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.

Strong legs, somewhat industrial but trendy also
Size: side table leg
Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.

Pretty good, take your time and install it well
Size: side table leg
Materials are pretty solid, but once assembled it’s not as sturdy as you would think it should be since the material itself was solid, i say give them a chance, everything out there that’s similar is way over priced

Heavy duty legs for table.
Size: side table leg
Perfect legs for a table I am having made. I have an cottonwood slice. It's heavy and needed something substantial. These are perfect.

Robust pipe & fittings with a beautiful, smooth black finish
Size: side table leg
This set of pipe & fittings for use as low table legs is heavy duty and aesthetically pleasing. Especially when the pieces are handled, the tactile sensation is much nicer than with plumbing steel pipe because this product is beautifully finished smooth. The black pipes are quite smooth as well as the fittings. The pieces are all also pretty robust, though the wall thicknesses are less than in pipe for pressurized water systems. Of course that makes sense as this product does not need to hold fluid pressure. In my view they got the heaviness factor of this product just right; it's not as heavy or robust as black pipe used in natural gas supplies, but still robust and pretty heavy. Assembled, this product is absolutely stiff and unyielding for a solid table that could hold a man's weight easily. The feet utilize a brilliant scheme so that each foot can be independently adjusted for an uneven floor. Thus a level table on an uneven floor is easily accomplished. The feet simply extend the effective leg length by screwing counter-clockwise. To prevent any shifting at the threads adding some pipe compound or teflon tape may be advised. Even masking or duct tape might work as the idea is to just fill any gaps where male threads meet female threads. The four flanges at the tops of the legs provide a wide, solid surface for attaching the table top, with either hidden screws underneath or you could through-bolt a glass table top (provided you have the skill to drill glass!). I think this product would look great with a glass top. Assembly is quick and easy. The hardest part is drilling holes underneath the table top to accept screws. No pipe wrenches are needed as the pieces screw together by hand to an adequate tightness. If any doubt whether they are tightened enough have a strong person with grippy gloves finish. The "X" in the center attaches to the legs with a very clever machine screw system tightened with the included hex wrench. This is presumably because if tightened simply by screwing the fittings, the point of snugness would not likely be where the "T" fittings are exactly vertical. The maker has solved this problem so that you are assured that all legs will be in the perfect vertical position once everything is tight. The setup is also nice and rigid once tightened. This is a huge benefit of steel pipe projects; they are really solid. The black finish is clearly very durable, like a powder coat. It appears that it will provide excellent protection against rust. Coverage is complete; I found no dings or scratches anywhere on any piece. Overall this is a very well-designed product for function and aesthetics. Perfect for a beautifully renovated warehouse condo where an industrial vibe is desired in a rock-solid table that won't shift around. The smoothness of the pipe is top notch. I've used lots of pipe in projects, some of it actual water pipe and some decorative pipe such as this. I've never seen better quality decorative pipe as this maker put in the effort to finish it beautifully smooth. At currently $34.99 I find the price quite reasonable too.
