Mini 4K HDMI Fiber Extender with RS232 & External Audio 80km HDCP 1.2Data 10.2Gbps

Product Overview

The LNK-MHRA4K Series is a high-performance Mini 4K HDMI Fiber Optic Extender designed for ultra-long-distance, multi-signal transmission in professional and residential applications. This advanced system supports uncompressed, lossless transmission of HDMI 1.4a video (up to 4K×2K@60Hz, YUV 4:2:0), RS232 serial data, and stereo audio over single optical fiber, extending signals up to 80 kilometers with zero latency and pristine signal quality.

Utilizing cutting-edge fiber optic technology, the transmitter converts HDMI signals into a high-speed 10Gb/s serial data stream, while the receiver accurately reconstructs the output for display devices. Engineered with superior anti-interference capabilities, the extender eliminates RFI/EMI emissions and ensures secure, stable performance in electrically noisy environments. Compliant with RoHS and international lead-free standards, it meets stringent requirements for global markets, including Europe and China.

Ideal for large-screen displays, professional conferencing systems, home theaters, broadcast studios, industrial control rooms, and digital signage, the LNK-MHRA4K Series delivers exceptional reliability and versatility for demanding AV and control applications.
