• Optical Fiber Interface
  • For use with Eclipse HX Digital Matrix systems
  • Interfaces with one or two digital matrix panels
  • Highly secure connections
  • 24-bit digital DEMUX
  • 48kHz audio sampling rate
  • Sends and receives RS-422 control data
  • Flat frequency response up to 20kHz, S/N >80dB
  • Up to 20km (12 miles) range with fiber using single mode
  • Up to 5km (3 miles) using multi-mode fiber
  • Works in demanding environmental conditions
  • RJ45 connectors for direct connection with matrix panels, frames and interfaces
  • Can be used to extend any line level 4-wire audio signal / RS-422 signal
  • Can be used with the earlier FIM-102D but the audio will require 5dB of gain.
Item Part Number:
  • FIM-S222
