• Secure Data transmission - Point to multipoint - Over ring optical fibre
  • Transmission over multimode or single-mode optical fibres by the same module
  • 1 bi-directional data, any configuration (RS232, RS422 or RS485)


HXDF-RR module enables one bidirectional point-to-multipoint data transmission over ring optical fibre to secure the communication.

The module has been designed specifically for networks where a central unit (master) communicates with stations (slaves) distributed on the loop.

  • Industrial networks
  • Electronically disturbed environment
  • Local area networks
  • Remote control

This equipmeent is available in stand-alone module version or in rack-mount version (7 TE) fully compatible with the 19”3U our 1U rack.

  • Data communication over one optical fibre to ensure secure transmission, even in an electronically disturbed environment up to 50 km.
  • The fibre optic loop connection allows secure communication.
  • The modules are connected in repeater over the fibre, the length of the optical ring is limited only by the maximum distance between two equipments.
  • Indicators and alarm contacts ensure to quickly detect the presence of a fault on the optical loop.
