Mini 4K/30Hz HDMI over Single-Core Multimode Fiber Extender
Model:LNK-108M
Overview
The LNK-108M is a high-performance Mini 4K/30Hz HDMI over Single-Core Multimode Fiber
Extender, featuring a pluggable design that connects directly to target devices—eliminating the
need for bulky intermediate hardware and making it ideal for space-constrained installations. As
a Mini 4K/30Hz HDMI over Single-Core Multimode Fiber Extender, it combines ultra-compact
dimensions with robust 4K video transmission capabilities, addressing the demand for both
portability and high-definition signal extension in modern AV systems.
This extender enables reliable extension of 4K video sources over single-core multimode
fiber up to 500m when paired with OM5 fiber, ensuring crisp, uncompressed 4Kx2K resolution
delivery to desired displays. Its core advantage lies in the absence of copper conductors: this
design minimizes RFI (Radio Frequency Interference) and EMI (Electromagnetic Interference)
emissions, while eliminating signal loss or video quality degradation—critical for environments
with complex electrical interference, such as industrial control rooms, medical imaging facilities,
or large-scale exhibition halls.
Enclosed as a dedicated HDMI optical module, the Mini 4K/30Hz HDMI over Single-Core
Multimode Fiber Extender supports transmission of uncompressed lossless HDMI 1.4 signals
over multimode fiber at 850nm wavelength. The system consists of two units: the LNK-108M-T
(transmitter) converts HDMI signals into a single 10Gb/s serial data stream for transmission over
a single optical fiber, while the LNK-108M-R (receiver) reconverts the serial data back to a standard
HDMI signal, preserving signal integrity throughout the transmission chain.
Compliant with RoHS standards and manufactured with lead-free materials, the extender meets
strict environmental regulations in Europe and China, aligning with global sustainability requirements.
Its strong anti-interference capability ensures stable signal operation even in harsh electrical environments,
while the compact form factor simplifies integration into AV racks, wall-mounted enclosures, or portable
multimedia setups. Suitable for large-screen display systems, high-end conferencing rooms, home
entertainment centers, digital signage networks, and professional AV installations, this Mini 4K/30Hz
HDMI over Single-Core Multimode Fiber Extender offers a reliable, space-efficient solution for long-
distance 4K video transmission with zero quality compromise.
