2 Channel PROFIBUS Fiber Optic Ring Module

101-201510The ComBricks Fiber Optic Ring modules for multi-mode and single-mode fiber technologies ensure reliable optical data transmission in PROFIBUS networks. These multifunctional modules are specifically designed to create reliable point-to-point, ring, bus, star and hub topologies. It allows long cable distances up to 30 km and a galvanic isolation between devices and segments.

The web server provides ProfiTrace diagnostic information extracted from all inserted modules. It even indicates the signal strength of the fibers. The fiber optic modules can be combined with repeaters and coupler modules.

ComBricks can be easily transformed to a remotely monitored fiber optic hub mixed with copper segments. The hub topology delivers an optimized delay time and live expansion.

The advanced core of the fiber optic module contains diagnostic LEDs and supports the redundancy feature. The fiber connection is utilized by 4 ST/BFOC connectors.
