BFOC/2.5 connectors

PROFIBUS stations with an optical interface generally use connectors of type BFOC/2.5. This worldwide standardized connector is also offered under the product name “ST connector” by some manufacturers

Other connector types

However, other connector types can also be found specifically for optical interfaces for plastic optical fiber. These connector types generally feature a simpler design than the BFOC/2.5 connector. The manufacturer’s instructions will show which connector type must be used. If in doubt, please contact the manufacturer of the PROFIBUS components.
