1Ch Bidirectional 3G-SDI with Loop-out + 1Ch Tally + 2Ch Bidirectional RS485 or RS422 + 2Ch Stereo Audio + 1Ch Microphone over Fiber Converter
Overview
The LNK-3G-1BV1T2BD2A1M Series represents an advanced fiber optic transmission solution engineered for professional broadcast and live production environments. This sophisticated converter integrates seven distinct signal channels through a single fiber optic link, combining bidirectional 3G/HD-SDI video with embedded audio, local loop-through monitoring, tally signaling, dual-channel bidirectional RS485/RS422 control, stereo audio transmission, and microphone input capabilities.
Utilizing advanced optical transmission technology, the system ensures broadcast-grade signal quality with full 1080P resolution support and compliance with SMPTE standards. The integrated loop-out functionality enables real-time local monitoring without interrupting the primary transmission path, while the comprehensive status indication system provides immediate visual feedback on all critical operational parameters through multi-color LED indicators.
Specifically designed for mission-critical applications, this converter delivers exceptional stability and reliability in demanding environments. The robust construction and advanced error correction mechanisms guarantee uninterrupted performance across extended distances, making it ideal for broadcast facilities, live event production, and security monitoring systems.
This versatile solution finds extensive application in intelligent transportation networks, educational campus systems, industrial automation monitoring (power generation, chemical processing, steel manufacturing, petroleum refining, railway operations), military security infrastructure (warehouse monitoring, border surveillance, guard post systems), television broadcast transmission, and stadium live production environments requiring high-definition video and multi-channel audio transmission with comprehensive control capabilities.
