Mini 4K HDMI Fiber Extender Long Distance Transmission Compact
Design Plug and Play
Overview
The LNK-108M Mini 4K/30Hz HDMI over Single-Core Multimode Fiber Extender is a
compact and high-performance HDMI optical transmission solution designed for
long-distance, uncompressed, and lossless 4K video signal extension. Supporting
HDMI 1.4 standards, this fiber extender enables stable and secure transmission of
ultra-high-definition (UHD) video up to 4Kx2K@30Hz over a single OM5 multimode
optical fiber at 850nm, reaching distances of up to 500 meters without signal degradation.
The transmitter module converts HDMI video into a 10Gbps high-speed optical data
stream for efficient transfer over one fiber core, while the receiver restores it back to the
original HDMI format with zero latency. Thanks to its plug-and-play design, the LNK-108M
extender easily integrates with displays, projectors, video walls, or digital signage systems.
Built with advanced EMI/RFI immunity and no copper conductors, it ensures secure,
interference-free data transmission—ideal for control rooms, broadcast studios,
conference systems, medical imaging, and home theater installations. The device is
RoHS-compliant and lead-free, offering excellent reliability and consistent performance
under demanding professional environments.
Features
High-Definition HDMI Transmission: Supports uncompressed HDMI video at
resolutions up to 4K/30Hz, delivering crystal-clear image quality over fiber optic connection
without signal distortion or delay.
Plug-and-Play Installation: Designed for easy deployment with no manual settings or
configuration required — simply connect and start transmitting high-resolution video
instantly.
Single-Fiber WDM Technology: Utilizes advanced Wavelength Division Multiplexing
(WDM) to simultaneously transmit high-definition audio and video signals through a
single OM3, OM4, or OM5 multimode fiber, significantly reducing cabling complexity.
Extended Transmission Distance: Provides stable data transmission up to 300 meters
on OM3, 400 meters on OM4, and 500 meters on OM5 fiber, ensuring consistent
performance in long-distance communication environments.
Professional HDMI Interface: Equipped with standard HDMI 1.4 connectors, supporting
a wide range of displays, monitors, projectors, and video wall systems.
Convenient Power Design: Integrated USB power connector, requiring only the receiver
(display side) to be externally powered, ensuring low energy consumption and simplified
wiring.
High Interference Immunity: TMDS signals are transmitted entirely over optical fiber,
providing strong resistance to EMI/RFI interference, ensuring stable operation in
industrial or broadcast settings.
Compact and Reliable Connectivity: Features a miniature form factor and durable LC
optical connectors, offering secure and stable data connections ideal for both portable
and fixed installations.
Hot-Swappable Design: Fully hot-pluggable modules enable quick setup and
replacement without interrupting existing video or data transmission.
