WSD-2/TXO and RXO Cyber Network SecurityNew

F/O UniDirectional Network/Data Diode, NISA Approved

  • Fast Ethernet single-direction transparent converters - Network Diodes for data transfers from/to secured sites
  • Approved by the Israeli National Information Security Authorization (NISA).
  • CIP device, TXO - Transmit only and RXO - Receive only
  • Pure HW unbreakable solution for single-direction data transfer, compatible with standard 100Base-TX and 100Base-FX link partners
  • Suitable for single-direction data streaming and UDP traffic as well as TCP based protocols or raw files transfers operated by any third-party unidirection SW application
  • Local or remote over F/O link in the range of 0-100Km
  • Fully transparent 3R conversion
  • Auto-negotiation, auto MDI and force modes
  • Enhanced Link Verification features:
    > Propagation Of No Link (PONL)
    > Far end-Fault Indication (FEFI)
  • Available for indoor, outdoor and industrial environments
  • Desktop, DIN rail and wall mounting options
  • External wide-range power supply
The WSD-2/TXO and WSD-2/RXO are unique single-direction “Transmit Only” and “Receive Only” full featured Fast Ethernet transparent converters providing 3R (Retiming, Reshaping and Regeneration) conversion between 100Base-TX copper media and 100Base-FX fiber media in compliance with IEEE802.3u standards.

Designed and approved for Critical Infrastructure Protection (CIP) applications, the WSD-2/TXO provides fully secured copper to fiber single-direction data transfer over single or dual fiber connection to a standard 100Base-FX link partner, whereas the WSD-2/RXO provides fully secured fiber to copper single-direction data transfer over dual fiber connection to a standard 100Base-FX link partner. Protection of the two sites is achieved using a pair of WSD-2/TXO and WSD-2/RXO connected back to back over single fiber in the range of (0-100Km).

Using standard bi-directional 100Base-TX connection with their copper link partners, the WSD-2/TXO and WSD-2/RXO unique technology enables single direction transfer over the fiber link respectively. Data transfer in the opposite direction is completely blocked by both the TXO and RXO HW circuitry.
