Micro Mini 4K HDMI Fiber Extender
Model:LNK-MH4K Series
Overview
The LNK-MH4K Series is a high-performance Micro Mini 4K HDMI Fiber Extender, meticulously
engineered to deliver uncompressed lossless 4K video transmission in an ultra-compact form factor
—ideal for space-constrained scenarios like small AV racks, wall-mounted display setups, or portable
multimedia systems where traditional bulky extenders are impractical. As a Micro Mini 4K HDMI Fiber
Extender, it balances miniaturized design with robust performance, ensuring seamless integration into
environments where installation space is at a premium without compromising on signal quality.
This extender is specifically designed to support transmission of uncompressed lossless HDMI 1.4a
signals over optical fiber, achieving a maximum transmission distance of 80km and delivering a clear,
stable resolution of 4Kx2K. Its transmitter unit converts HDMI signals into a single 10Gb/s high-speed
serial data stream, which is transmitted over optical fiber to minimize signal attenuation and maintain
integrity even across long distances; the receiver unit then accurately reconverts the serial data back
to HDMI signals, ensuring no loss of video detail or delay from source to display.
Compliant with RoHS standards and lead-free, the Micro Mini 4K HDMI Fiber Extender meets strict
environmental regulatory requirements in Europe and China, aligning with global sustainability norms
for electronic products. It also boasts strong anti-interference capabilities, effectively resisting
electromagnetic interference (EMI) and radio frequency interference (RFI) common in industrial sites,
busy office buildings, or high-density AV environments—critical for ensuring consistent signal stability
in complex electrical scenarios.
With its reliable performance and ultra-compact design, this product is suitable for a wide range of
applications beyond traditional large-screen displays, conferencing systems, and home entertainment:
it also excels in professional AV installations (such as museum digital exhibits), remote monitoring centers
(for 4K security cameras), and corporate digital signage networks. The Micro Mini 4K HDMI Fiber Extender’s
combination of miniaturized design, long-distance transmission, uncompressed 4K quality, and anti-interference
performance makes it a versatile, space-efficient solution for modern high-definition video transmission needs.
