RS-232 Point-to-Point
Fiber Optic Modems
Fiber Converters


These fiber converter products convert an RS-232 electrical signal into light signals for transmission over fiber optic cable. RS-232 fiber converters provide fully transparent operation with data, clock, and common control signals automatically multiplexed.


  • Data Rates to 100 Kbps Source Timing
  • Data Rates to 128 kbps Terminal Timing
  • Distances to 20 km
  • Choice of multimode or singlemode
  • Standalone or rack-mount
  • SFP Fiber Optic Module Technology

RS-232 Set Up


NOTE: One of our more unusual applications for the RS-232 products include a university research project
utilizing the RS-232 MicroModems underwater to count sea plankton. These same units are also being used
to monitor the count at surface level.

Another interesting application makes use of the M8000 MicroModems to transmit RS-232 switch control signals
over fiber in order to ensure safe operations at airports.
