Mini HD-SDI Fiber Converter Tally & RS485 80km 8-Ch Audio Hot-Pluggable
SDI Fiber Converter Overview
The LNK-MHD-1V Series represents a space-efficient fiber optic transmission solution engineered for professional broadcast and live production environments. This miniaturized converter seamlessly transmits one channel of HD-SDI video with embedded audio, tally signaling, and reverse RS485 control data through a single fiber optic cable.
Featuring local loop-through output capability, the system enables real-time signal monitoring while maintaining the integrity of the primary transmission path. The complete transmitter and receiver set ensures reliable HD-SDI signal quality with precise timing synchronization, making it ideal for camera-back applications and broadcast interconnects.
Specifically designed for space-constrained installations, this compact converter is particularly suitable for outside broadcast vehicles, fly-pack systems, and equipment racks where physical space optimization is crucial. The integrated tally system provides reliable camera status indication, while the reverse RS485 interface enables comprehensive remote camera control for PTZ operations and equipment management.
Utilizing advanced optical transmission technology, the system guarantees complete electrical isolation and immunity to electromagnetic interference. This robust construction ensures stable performance in demanding production environments, from studio settings to remote field locations. The converter's plug-and-play operation simplifies installation while maintaining broadcast-grade signal quality throughout the transmission path.
