The FIM-4W2 optical fiber interface allows one or two digital matrix intercom user panels, interface modules or 4-wire sources to be remotely connected to Eclipse, Eclipse HX and Matrix +3 intercom systems over optical fiber. A pair of FIM-S222 interfaces is required for each fiber link; one at the matrix frame and the other at the matrix user panel.


  • Compact 2-channel interface box
  • Remotely locates one or two digital matrix panels or interface models over fiber
  • 24-bit digital DEMUX
  • 48kHz audio sampling rate
  • Sends and receives RS-422 control data
  • Flat frequency response up to 20kHz, S/N >80dB
  • RJ45 connectors for direct connection with matrix panels, frames and interfaces
  • Can be used to extend any line level 4-wire audio signal
  • Can be used to extend any RS-422 signal
