Networking with fiber optics

Networking with fiber optics

Interference-free and powerful

Data transmission over fiber optics.

Our FO converters support conventional communication protocols used in remote control technology, such as PROFIBUS, Modbus/RTU, Ethernet, and the RS-232 and RS-485 interfaces. The main advantages compared to conventional copper-based data transmission are the electromagnetic immunity, the high-quality electrical isolation of the optical path, and the achievable distances of up to 45 km. Benefit from these advantages in your sophisticated remote control application.

Your advantages

  • Automatic monitoring and display of the optical signal quality
  • Warning of failure via floating switch contact
  • Operating state indicated via diagnostics LED
  • Robust devices with extended temperature range
  • Device-specific approvals: ATEX, UL HazLoc, operation at altitudes of up to 5,000 m

Modular PSI-MOS hub

All PSI-MOS converters have a modular design. They can be combined with a system power supply and other devices to create a modular hub.

Fast diagnostics in the event of a malfunction

Redundantly networking system parts with FO media converters

In addition to numerous diagnostics LEDs, the media converter also features the link management function (link fault pass through). This ensures permanent connection monitoring. Both sides of the network connection can therefore detect a lost link immediately. The entire connection over the optical path is therefore as transparent is it would be if communication were purely copper-based. In the event of a network interruption, the transmission path is switched off. Redundancy mechanisms can be used directly.

In addition, when the FEF (far end fault) function signals a lost link to the media converters, this also enables the faulty segment to be localized.

Communication via fiber optics to remote systems

Networking remote systems with fiber optics

One advantage of optical data transmission is the increase in the maximum range. Only distances of one hundred meters between two devices can be achieved with copper-based Ethernet communication.

This distance is sufficient for small systems, but is much too short for communication to remote systems. With fiber optic cables and industrial media converters or switches, on the other hand, distances of several kilometers can be reached without difficulty for a point-to-point connection.
