Gefen Dual Link DVI Fiber Optic Modular Extender

Extend Dual Link DVI up to 1000 feet (300 meters) over two fiber optic cables with the Gefen Dual Link DVI Fiber Optic Modular Extender. Built for professional AV installations, this modular system uses DVI FM 2000 transmitter and receiver modules to translate, transmit, and re-create high-resolution DVI signals across long distances with precision and reliability. By leveraging two strands of SC multimode fiber, it delivers a stable, EMI-free video path from source to display, making it an ideal solution for control rooms, classrooms, corporate environments, digital signage networks, and production studios where imaging quality and distance matter most.

• Extend Dual Link DVI up to 1000 feet (300 meters) over two SC multimode fiber cables, enabling long-distance video distribution without compromising image quality or timing.
• Modular architecture with DVI FM 2000 transmitter and receiver modules for flexible deployment, easy serviceability, and future upgrades in a compact footprint.
• Supports both single-link and dual-link DVI resolutions, enabling a wide range of displays from standard-definition setups to high-resolution 2560x1600-class monitors, depending on source, display, and cabling.
• Fiber-optic transmission provides immunity to EMI and RF interference, ensuring pristine video even in electrically noisy environments or installations near equipment racks, power lines, or machinery.
• Designed for professional installations with straightforward, scalable integration—works with standard DVI sources and displays and allows simple expansion to multiple displays or longer runs by swapping in compatible modules.

Technical Details of Gefen Dual Link DVI Fiber Optic Modular Extender

• Modules: DVI FM 2000 transmitter module and DVI FM 2000 receiver module form the core of the modular extender, enabling a flexible point-to-point setup with potential for expansion.
• Architecture: Modular, field-serviceable design that supports upgrades, easy replacement of modules, and adaptable topologies for various installation scenarios.

how to install Gefen Dual Link DVI Fiber Optic Modular Extender

Installing this extender is straightforward and designed for professional AV workflows. Follow these steps to ensure a reliable, high-quality video link:

• Prepare your equipment: power down the source device, display, and any intermediate equipment before making connections.
• Connect the source: attach the DVI output from your video source to the transmitter module’s DVI input. Use a high-quality DVI cable to minimize signal degradation.
• Run fiber to the receiver: connect two SC multimode fiber cables from the transmitter to the receiver, ensuring the fibers are clean and properly seated in the SC connectors. Maintain correct fiber polarity if required by your specific installation guidelines.
• Connect the display: attach the DVI input of your display to the receiver module’s DVI output, using a short DVI cable to minimize potential signal loss.
• Power the system: apply the appropriate power supply to both transmitter and receiver modules. If your kit includes external power adapters, ensure they are compatible with the modules and securely connected.
• Verify operation: power on the source, transmitter, receiver, and display. Check for video signal, alignment, and color accuracy. If you encounter artifacts or no signal, reseat connectors, verify fiber integrity, and confirm that the modules are correctly matched (transmitter to receiver).
• Optimize placement: position the transmitter near the source and the receiver near the display to reduce cable clutter and improve ventilation. Ensure fiber cables are not tightly bent and are protected from physical damage.
• Documentation and support: reference the manufacturer’s installation manual for any model-specific steps, safety guidelines, or warranty information. If you encounter issues, consult qualified AV technicians or Gefen support for guidance.

Frequently asked questions

• What distance can I extend with this DVI fiber optic modular extender? — Up to 1000 feet (300 meters) between the transmitter and receiver when using two SC multimode fiber cables, enabling long-range distribution without sacrificing image quality.
• What type of fiber cables are required? — Two SC multimode fiber optic cables (one for each leg of the Dual Link DVI signal). The cables should be clean, properly terminated, and of sufficient bandwidth to support the target resolution.
• What resolutions are supported? — The extender supports single-link and dual-link DVI resolutions up to the maximum defined by DVI standards (for dual-link configurations, commonly up to 2560x1600 at 60 Hz, subject to source/display capabilities and cable quality).
• Is HDCP preserved through the extender? — DVI-based signaling typically carries HDCP; compatibility depends on the source and display. The extender is designed to preserve the video signal characteristics along the path where HDCP is supported.
• Are power supplies included and how easy is maintenance? — Power supplies may be included with some kits; otherwise, they are sold separately. The modular FM 2000 design facilitates field maintenance and module replacement without replacing the entire extender.
• Can I expand this setup to drive more displays? — Yes, the modular design supports flexible configurations; you can add additional transmitter/receiver pairs or upgrade modules as needed to accommodate larger installations.
