Kramer 614R/T Single-Fiber Detachable DVI Optical Transmitter & Receiver

The Kramer 614R/T Single-Fiber Detachable DVI Optical Transmitter & Receiver represent a compact, high-performance solution for delivering uncompressed DVI video over a fiber optic link. This pair—the 614T transmitter and the 614R receiver—is designed to be lightweight, easy to install, and exceptionally reliable for professional AV environments. By converting DVI signals to optical and back again, these units enable crystal-clear digital video transmission across distances where copper cables would struggle, while staying immune to EMI and RF interference that can plague traditional HDMI/DVI runs. Ideal for boardrooms, classrooms, museums, digital signage, and broadcast environments, the 614R/T is built to preserve image fidelity and color accuracy from source to display.

• Detachable transmitter and receiver: The 614T and 614R form a flexible, two-piece solution that can be mounted or tucked into tight spaces, allowing for discreet and tidy installations while delivering robust, fiber-based video transmission.
• Uncompressed DVI transmission up to 1920x1200 at 60 Hz: The pair preserves full image quality without compression artifacts, ensuring sharp text, precise graphics, and accurate color reproduction on high-resolution displays.
• Single-fiber, multimode fiber link with SC connectors: A streamlined, cost-effective fiber setup that minimizes cabling clutter while delivering dependable performance over a fiber path that is resistant to electrical interference.
• Compact, lightweight design for easy installation: Both modules are designed to minimize space requirements and simplify mounting in equipment racks, under tables, or behind displays, making upgrades or retrofits straightforward.
• Plug-and-play compatibility with standard DVI sources and displays: The 614R/T pair works with common DVI-D devices, providing a straightforward upgrade path for AV professionals seeking blade-free fiber HDMI/DVI solutions without complex configuration.

In use, the Kramer 614R/T system behaves as a clean, point-to-point DVI extension over fiber. The transmitter takes the DVI video signal from a source such as a computer, media player, or presentation device, converts it into a fiber-deliverable optical signal, and sends it across a single multimode fiber to the receiver. The receiver then converts the optical signal back into a DVI signal for the display, ensuring a faithful reproduction of the original image. This approach is particularly advantageous in environments with stringent distance requirements, challenging electrical environments, or architectural constraints that make long copper runs impractical. With the 614R/T, installers can achieve reliable long-distance transmission without sacrificing resolution, color depth, or latency performance.

Key benefits include improved signal integrity over long runs, reduced susceptibility to electromagnetic interference from nearby equipment, and a clean, professional installation that keeps cables out of sight. The system’s single-fiber design reduces cable management complexity while maintaining high-quality video delivery. Whether your project involves conference rooms, classrooms, museum displays, or retail environments, the 614R/T provides a scalable, future-proof method to extend DVI signals without degradation. The product’s lightweight construction and detachable pair design also support serviceability and upgrades, making maintenance quick and efficient for system integrators and IT managers alike.

How to install Kramer 614R/T

• Mount or position the 614T transmitter next to the DVI source and connect the source’s DVI-D output to the transmitter’s DVI input using a standard DVI-D cable.
• Route a single multimode fiber cable with SC connectors from the transmitter to the location of the 614R receiver, ensuring the fiber is clean and properly terminated.
• Connect the 614R receiver to the display’s DVI input with another DVI-D cable, ensuring secure connections on both ends.
• Power both the transmitter and receiver units with their respective power supplies. Verify that the link status indicators (if present) show an active connection.
• Power on the source and display, then select the appropriate resolution (up to 1920x1200 at 60 Hz) on the source to ensure a clean, artifact-free image. If necessary, adjust EDID settings on the display to match the source capabilities.

Frequently asked questions

• Q: What resolutions does the Kramer 614R/T support? A: It supports uncompressed DVI resolutions up to 1920x1200 at 60 Hz.
• Q: What type of fiber is required? A: A single multimode fiber with SC connectors is used for the link between the transmitter and receiver.
• Q: Is the video signal compressed? A: No. The system transmits uncompressed DVI to preserve image quality and color fidelity.
• Q: Is this a bidirectional link over a single fiber? A: The 614T and 614R are a transmitter and receiver pair for a point-to-point link; the typical configuration is a unidirectional path from the transmitter to the receiver.
• Q: Do I need software or complex configuration? A: No software is required. It is designed as a plug-and-play DVI over fiber solution, with straightforward setup and operation.
