FibreOptic foRS232

Part No.: MPPT-FibreOptic-foRS232
Bidirectional, up to 116 kBaud



  • 8 x In, 8 x Out, each channel "RxD+TxD, w/o handshake" or 4 x, each channel "Rx+Tx+TRS+CTS, w handshake"
  • Bidirectional, up to 116 kBaud
  • >1.000 m, depends on No of Patches
  • EMC compliant to CISPR 25, Class5


In complex testing environments it is often needed that electrical signals have to be transmitted into the chamber or out of the chamber to the test equipment.

For that purpose we offer a variety of different interfaces that convert electrical signals into optical signals and back. Such the signal can be transmitted via fibre optics and is immune against electrical fields.

A sophisticated shielding and filtering concept ensures that the interfaces are highly immune against radiation and do not deliver out any significant emission.

In most cases both units are shielded.



  • RF-Immunity: works appropriate, no test report
  • Emission: EMC compliant to CISPR25 Class 5, 150 k – 4 GHz
  • Battery (approx. 8 hours operation) or mains powered
  • Compact metal housing
  • No galvanic connection between test equipment and measurement instruments


  • Standard
    • One set consists of two converter units:
      • Converter 1: Satellite
      • Converter 2: Transceiver (un-shielded)
    • ncl. Modem link cable
    • All converters are shipped with the appropriate power supply or battery and charger.
  • Optional
    • Fibre optic cables: variable lengths ST/FSMAconnector or ST/ST-connector
    • FO-Patches (Feed Through wall Patches)
