9 Fiber optic module (2FO-001)

The 2 channel PROFIBUS fiber optic module is suitable for 3 km multimode cable. This module

enables long cable distances and a galvanic isolation between devices and segments. It can be

deployed in a point-to-point, bus, star and hub topology.

The fiber optic modules can be placed side by side with repeaters modules. Just like any other

communication module, the channels are directly connected with the ProfiTrace OE core in the

Head Station. Busmonitor data is directly available in the web server.

ComBricks can easily be transformed to a fully dedicated fiber optic hub mixed with copper

segments. The hub topology delivers an optimized delay time and 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. The fiber

connection is utilized by 4 ST/BFOC connectors.



The 2FO-001 does not support ring redundancy.

See chapter 10 for modules that do support ring topologies.

The ComBricks fiber optic module supports multiple topologies: point-to-point, bus, star and hub topology (see

Fig. 57).
