HD-SDI to Fiber Converter
HD-SDI to Fiber Converter Features
1.High-Definition Broadcast & Live Production Links
Ideal for broadcast contribution and studio-to-transmitter (STL) links, transporting HD-SDI signals with embedded audio over long distances. Provides jitter-free, uncompressed video transmission for live event production, OB vans, and remote broadcast centers, ensuring signal integrity and timing accuracy.
2. Long-Distance CCTV & Security Surveillance Systems
Deployed in large-scale perimeter security and city-wide surveillance networks. Extends HD-SDI camera feeds from remote locations—such as airports, harbors, and critical infrastructure—to central monitoring stations over single-mode fiber, eliminating EMI/RFI interference and enabling real-time monitoring up to 80km.
3. Traffic Management & Intelligent Transportation Systems (ITS)
Supports high-definition video transmission in traffic control centers and ITS networks. Used for license plate recognition (LPR), traffic flow monitoring, and incident detection systems along highways and tunnels, providing stable, long-haul connectivity for HD-SDI traffic cameras with bi-directional data control.
4. Professional A/V & Large-Venue Signal Distribution
Enables signal extension in stadiums, convention centers, and command & control rooms. Distributes multi-channel HD video with embedded audio from production switchers to display walls or projectors over fiber, supporting low-latency, high-fidelity A/V integration in complex installations.
5. Industrial & Harsh Environment Video Monitoring
Designed for extreme environment video applications in oil & gas facilities, power plants, and mining operations. Its industrial-grade housing and wide temperature tolerance ensure reliable operation for process monitoring, safety inspection, and remote visualization where electrical noise and temperature extremes are present.
HD-SDI to Fiber Converter Overview
The LNK-HD-110 Series is a professional-grade, single-channel HD-SDI fiber optic converter engineered for high-definition video surveillance and broadcast applications. This compact solution seamlessly transmits embedded-audio HD-SDI video signals and bidirectional RS422/RS485 control data over single-mode or multi-mode fiber optic cable, ensuring zero-loss, long-distance signal integrity.
Featuring a built-in HD-SDI loop output for local video monitoring, this converter set includes a dedicated transmitter and receiver pair, providing a complete point-to-point link for critical video transport. Designed to eliminate electromagnetic interference (EMI) and signal degradation common in copper-based systems, it delivers pristine, uncompressed video quality for mission-critical operations.
Ideal for security monitoring, broadcast contribution links, and industrial visualization, the LNK-HD-110 Series enables reliable connectivity over distances far exceeding standard coaxial cable limitations. Its robust performance makes it the perfect choice for extending high-definition video feeds in CCTV systems, traffic control centers, stadiums, and other demanding environments where signal fidelity and reliability are paramount.
