4K DVI Fiber Optic Extender Long Distance Uncompressed Stereo Audio Transmission

Mini 4K DVI Fiber Optic Extender with Audio Up to 80km Transmission Range

Overview

The LNK-MDA4K Series Mini 4K DVI Fiber Optic Extender with Stereo Audio is an advanced fiber

transmission solution designed for extending uncompressed 4K DVI video and high-fidelity audio

signals over a single optical fiber cable. It supports ultra-long-distance transmission up to 80km,

delivering crystal-clear 4K×2K@60Hz (YUV 4:2:0) resolution with zero latency and no compression.

This 4K DVI fiber extender converts DVI and audio signals into a high-speed 10Gbps optical data

stream, ensuring stable, interference-free performance and exceptional image quality across long

distances. Engineered with RoHS compliance and lead-free design, it meets global environmental

standards.

The compact, plug-and-play design makes it ideal for professional AV systems, large-scale display

installations, conference centers, broadcast studios, control rooms, and home theater systems.

With its robust anti-interference capability and consistent signal reliability, it provides a perfect solution

for high-end video and audio transmission applications requiring long-range stability and premium

performance.
