Data Diode was designed with Bidirectional communication. The two way Data Diode with separated send and receive nodes are completely isolated from each other.

Bidirectional transfer of data over fiber cable or copper cable between two networks with hardware separation to guarantee security.

Fiber or Copper interface can be chosen independantly for In and Out. No need for extra converter!

Product details


The Fibersystem Data Diode Bidirectional gives the following advantages:

  • Based on hardware, no extra software needed. This completely eliminates the risk for data flowing in false direction
  • Fiberoptical links for galvanic seperation between networks
  • Supports: Syslog, NTP Broadcast, SNMP traps
  • Supports: UDP (Unicast, Broadcast, Multicast, Manycast)
  • For Queue Mgmt, Logging, Mail, FTP, SNMP and SDK. Additional software is needed


  • Fiber/copper connectivity
  • 1 Gbit/s
  • Tempest Level A (NATO standard)/ EMSEC/ RÖS U1 against eavesdropping
