Long cable distances and galvanic isolation between devices and segments

The PROFIBUS Fiber Optic module is a unique product that allows long cable distances and galvanic isolation between devices and segments. This module is perfectly suitable for point-to-point-, bus-, star- and hub topologies.

Because busmonitor data is directly available in the web server, the Fiber Optic module allows technicians to optimal maintenance of a PROFIBUS installation.

The fiber optic modules

The Fiber Optic modules can be placed side by side with repeater modules. Just like any other communication module, the channels are connected directly to the ProfiTrace OE core in the Head Station.

ComBricks can also easily be transformed into a fully dedicated fiber-optic hub mixed with copper segments. The hub topology delivers an optimized delay time and enables live expansion. The advanced 12 Mbps core of the fiber optic module can be cascaded unlimitedly with other fiber modules. It contains diagnostic LEDs and supports the redundancy feature.
