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.

A real review.
Color: 2PC, Color: 2PC
When I saw the Unbreakable Teddy Extreme Bear 2.0, I thought, Finally! A toy that might survive my 9-month-old Rottweiler puppy, Pepper. She’s an aggressive chewer with a love for stuffies—she adores them, right up until she disembowels them and feasts on their cotton insides like a tiny, unhinged zombie. The toy’s name, "Unbreakabear," sounded promising. Durable? Stuffie-like? For large breeds? Sign me up! Fifteen minutes later, it looked like a crime scene from a horror movie. The Good: Pepper was IN LOVE with this toy... for about 10 minutes. The double pack is nice in theory—you know, so you have a backup when the first one inevitably doesn’t live up to its "unbreakable" promise. The Bad: False Advertising: This toy is marketed as "extremely durable for aggressive chewers." But let me tell you: Pepper’s chewing isn’t aggressive—it’s surgical. She shredded the bear’s ears, ripped off the tail, and then went straight for the brain like she was auditioning for Zombie Dogs Gone Wild. It didn’t even put up a fight. Durability (or Lack Thereof): Calling this toy "extreme" is like calling a paper towel roll a chew toy. One good shake, and the seams basically exploded in surrender. Safety Concerns: Once Pepper exposed the stuffing (and the metaphorical "brains"), it was a race to see if I could stop her from swallowing it. Stuffing everywhere. The floor looked like someone had murdered a carnival bear. The Ugly: Walking into the room after Pepper was done was like stumbling upon the aftermath of a teddy bear massacre. The "Unbreakabear" lay limp on the floor, its ears and tail missing, stuffing spewed around like it was the victim of a bear-sized horror flick. Pepper, triumphant, sat there with bits of fluff clinging to her mouth, looking like a deranged extra from The Walking Dead. Final Thoughts: If your dog is a light chewer who likes to gently cuddle their toys, this might be fine. But if your dog sees toys as a challenge, run. Stick to hard rubber toys, Kongs, or something without a vulnerable, squishy middle. As for the warranty? Sure, I could try to get a replacement, but what’s the point? Pepper will just go full zombie surgeon again. Would I recommend this toy? Only if you’re filming a sequel to Teddy Bear Massacre. For aggressive chewers, this is nothing but fluff and disappointment. Pepper’s Review: 5/5 stars for taste. 0/5 stars for durability.

Toy does not live up to its name
Color: 1PC
This product is not sturdy enough for an aggressive chewer as it is advertised. It took my 7-year-old "Rottie" approximately 15-20 minutes to have this "unbreakable, in destructive aggressive chewer" toy rip open and stuffing everywhere. A complete waste of money and I would not recommend this toy to anyone with an aggressive chewer.

Total Rip Off Zero Star Rating Warranted
Color: 1PC
I purchased this product for my dog because it was advertised as indestructible. The second my dog opened the package and put the bear in his mouth the “indestructible bear” was torn apart just below the bear’s head. It was useless and the stuffing was exposed. We had to take the bear from our dog and throw it away. The product was literally destroyed, rendered useless, and unusable in seconds. We had to take the product from our dog fearing he would infest the stuffing which I’m sure would have been harmful to our dog. I have never seen a dog toy that was so easily torn apart and this has never happened to any of the many toys we have purchased and/or given to our dog for play toys. I would rate this product zero stars if possible. Unfortunately one star is the lowest rating you can give when submitting your review. I’m embarrassed I spent money on what truly is junk. We and anyone else should demand a refund for purchasing this product. Sincerely One Disappointed and Disgusted Amazon Prime Member
