  • Two Multimode versions available 850nm or 1310nm
  • Duplex LC optical connections
  • Supports hot swapping and hot plugging

* Distance is an approximation. Actual distances achieved can be longer or shorter depending on the type of fiber cable and accumulated optical losses in the fiber link. Determine link losses and perform optical budget calculations to ensure correct operation.


The OTR 1210 is a MADI fiber transmitter and receiver combined in a single package. The module is designed to convert up to 64 audio channels bi-directionally (64 IN & 64 OUT) between MADI Optical and MADI Coaxial (electrical) formats. Conversion is real time [no latency] and does not degrade the signal quality.

The OTR 1210 is compact and cost effective solution to extend the reach of MADI audio over long distances. When paired with another OTR 1210 at the receiving end (using two singlemode fiber links) you have a cost effective, zero latency MADI extender system for distances up to 10km*

Three versions are available. The singlemode fiber version will transport MADI over distances up to 10km*, and the Multimode versions up to 550m*.

Note: For connectivity to third party MADI Multimode fiber equipment the 1310nm version should be used.
