Card Module Data Diode 100Mbit

Fibersystems Data Diodes are used to allow secure networks to receive data from open/general purpose networks. Unidirectional datatransfer over fibercable or coppercable with hardware separation to guarantee security. This completely eliminates the risk for dataflow in false direction


  • One-way connection between two networks (also known as Simplex)

  • Based on hardware. No physical risk of sending data in false direction

  • Fiber optical links for galvanic separation between networks

  • UDP and SNTP support

  • Can be used in any ethernet application using fiber or copper connectivity

  • All data will be transparently forwarded, no extra software needed. The datalines are psysically cut/interrupted on circuit board. This completely eliminates the risk for data flowing in false direction
