Lynx Technik yellobrik OTR 1240 MADI Coax to MADI Fiber Transceiver (CWDM)

The OTR 1240 is a versatile MADI fiber transceiver designed to convert up to 64 audio channels bi-directionally between MADI optical and MADI coaxial (electrical) formats. This real-time conversion ensures zero latency and maintains the integrity of the signal without any degradation. The compact design offers a cost-effective solution for extending MADI audio over long distances. When paired with another OTR 1240 at the receiving end (utilizing two fiber links), it forms a zero-latency MADI extender system capable of covering distances up to 40 km (24.8 miles). Additionally, the module provides 18 selectable CWDM wavelengths, facilitating integration into multiplexed CWDM environments. :contentReference[oaicite:4]{index=4}
