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.
