In both indoor and outdoor optical networks data is transferred using fiber optic cables. These contain glass or plastic fibers and use trailing cables or a halogen-free design. Siemens’ PROFIBUS OLM (optical link module) and OBT (optical bus terminal) provide the essential components for a PROFIBUS optical network in a linear, star or redundant configuration.
Multiple potential applications
The PROFIBUS OLM and OBT bus terminals allow optical networks to achieve transfer rates as high as 12 Mbit/s regardless of the range.
Potential applications include deployment with high EMC levels; networking among multiple buildings; in networks with mixed electrical and optical PROFIBUS segments; and in long-range networks such as those used in transportation tunnels or traffic control systems.
FastConnect - the complete system
For quick and error-free installation or changes on site, with FastConnect, Siemens has developed a sophisticated quick-assembly system of cables, plug-in connectors and assembly tools. FastConnect is available for Industrial Ethernet/PROFINET and PROFIBUS, for RJ45, M12 or sub-D/RS 485. And now also for fiber-optic cables: BFOC, SC, SC RJ and LC (pre-assembled) in various lengths. With FastConnect FO, the impossible is now possible!
Less time is spent connecting terminals
Greater flexibility due to configuring the optimum cable length with the right connector for the terminal directly on site
Prefabricated cables can be ordered to reduce assembly and inspection time
Easy installation using just one tool
Easy routing of cables with pre-assembled connectors
Mistakes are prevented thanks to color coding and the transparent contact cover
