Lynx Technik yellobrik OBD 1210 MADI Coax to MADI Bidirectional Fiber Transceiver

The OBD 1210 system addresses the need for long-distance transmission of MADI signals by converting them between optical and coaxial formats. This bidirectional system supports up to 64 audio channels in both directions, making it ideal for applications requiring high-quality audio transmission over extended distances. The modules operate in real-time without introducing latency or degrading signal quality, ensuring reliable performance. Utilizing WDM optical multiplexing, the system requires a single bidirectional fiber link between the modules, supporting distances up to 10 km over single-mode fiber. It's important to note that this system is designed for point-to-point applications and cannot be integrated into a CWDM multiplexed system. :contentReference[oaicite:4]{index=4}
