Mini 4K DVI Fiber Extender with RS232, up to 80km Transmission Distance

Overview

The LNK-MDR4K Mini 4K DVI Fiber Optic Extender with RS232 enables long-distance

transmission of uncompressed 4K DVI video and RS232 control signals over a single optical

fiber. Supporting resolutions up to 4K×2K@60Hz (YUV 4:2:0), this compact extender ensures

crystal-clear video quality and low-latency signal performance over distances up to 80

kilometers.

The transmitter module converts the DVI input into a high-speed 10Gbps optical data stream,

while the receiver restores it back to a standard DVI signal with full integrity and no compression

loss. Engineered with high interference immunity and excellent signal stability, the extender is

RoHS compliant and fully lead-free, meeting environmental standards in both Europe and China.

This fiber optic DVI extender is widely used in large-screen video walls, conference room

systems, control centers, and home theater installations, offering professional-grade reliability

and high-quality 4K signal transmission for any demanding AV or communication environment.
