Data Diode 100BaseTX to FX MM

Data Diodes are used to allow secure networks to receive data from open/general purpose networks. Unidirectional transfer of data over fiber cable or copper cable between two networks with hardware separation to guarantee security. This completely eliminates the risk for data flowing in false direction. Fiber or Copper interface can be chosen independantly for In and Out. No need for extra converter!

For more information about Data Diodes, please visit:


  • 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
