With the PROFIBUS OLM (Optical Link Modules), optical PROFIBUS networks can be established in linear, star and redundant ring topologies.

The data transfer rate of a fiber optic line is independent of the distance and can be up to 12 Mbit/s.

Possible applications for OLMs include:

• System buses based on PROFIBUS
• Networking between buildings using glass fiber optic cable
• Mixed networks with electrical and optical segments
• Networks covering a wide area (road tunnels, traffic control systems)
• Networks with high availability requirements (redundant ring networks)
