Mini HD-SDI over Fiber Extender

Model: SDI Fiber Extender


Overview

The LNK-MHD Series is a professional-grade Mini HD-SDI over Fiber Extender with Long
transmission capability up to 80 km, specifically engineered to enable stable, high-fidelity
transmission of 1-channel HD-SDI video signals (with embedded audio) via fiber optical
cables. As a Mini HD-SDI over Fiber Extender with Long transmission capability up to 80
km, it integrates compact design with long-distance signal transmission performance,
addressing the needs of scenarios requiring both space efficiency and remote HD video
delivery.
​
This extender system consists of one dedicated transmitter unit and one matching receiver
unit, forming a complete HD-SDI signal transmission link that adheres to HD-SDI industry
standards. The embedded audio function ensures synchronized audio-video transmission,
eliminating issues like latency, frame loss, or sound-video desynchronization—critical for
professional applications where signal consistency is non-negotiable. Its core advantage
lies in the long transmission capability of up to 80 km, which far exceeds short-range fiber
solutions, making it suitable for cross-regional HD video backhaul, such as remote surveillance
signal transmission between cities, or broadcast signal delivery from outdoor live venues to studio
control rooms.
​
With an ultra-compact form factor, the Mini HD-SDI over Fiber Extender with Long transmission
capability up to 80 km can be easily integrated into other devices or installed in space-constrained
environments—including small surveillance cabinets, portable broadcast terminals, or outdoor
equipment enclosures—without occupying excessive space. It adopts a robust fiber transmission
architecture that effectively resists electromagnetic interference (EMI) and radio frequency interference
(RFI), common in industrial or urban environments, ensuring that HD-SDI signals maintain broadcast-
level quality even over the maximum 80 km distance.
​
Widely applicable in professional fields such as high-definition security surveillance (e.g., long-range
highway, railway, or border monitoring), and broadcasting (e.g., 中小型电视台 remote signal acquisition,
live event video transmission), this extender provides a cost-effective, reliable solution for long-distance
HD-SDI signal delivery. Its combination of miniaturized design, 80 km long transmission capability, and
stable audio-video synchronization makes it a practical choice for scenarios where remote, high-quality
HD video transmission is essential.
