4-Channel Bidirectional 3G-SDI Fiber Converter 120km Range Broadcast Grade
Overview
The LNK-3GSDI-4BV Series represents a high-performance fiber optic transmission solution engineered for professional broadcast and video production environments. This advanced system enables simultaneous transmission of four independent 3G-SDI video channels in bidirectional configuration over a single fiber optic cable, significantly reducing infrastructure costs while maintaining broadcast-grade signal quality.
Our innovative fiber converters utilize cutting-edge optical transmission technology to deliver uncompressed 1080P high-definition video with exceptional clarity and stability. Each channel features independent 3G/HD-SDI loop-through outputs for local monitoring, providing real-time signal verification without compromising the main transmission path. The system fully complies with 3G-SDI standards (SMPTE 424M, 292M, 259M), ensuring seamless integration with existing broadcast equipment and infrastructure.
Beyond video transmission, this comprehensive solution incorporates a dedicated reverse RS-485 data channel, enabling bidirectional control communication for PTZ cameras, robotic systems, and other remotely operated devices. The integrated architecture supports crystal clear audio transmission with CD-quality performance, making it ideal for demanding applications where audio-video synchronization is critical.
Specifically designed for mission-critical video distribution, this system provides complete electrical isolation and immunity to electromagnetic interference, ensuring reliable operation in electrically noisy environments. The robust construction and advanced error correction mechanisms guarantee uninterrupted performance for broadcast studios, live event production, sports venues, and security monitoring applications requiring multi-channel HD video transmission with precise control capabilities.
