Product Description

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.
