SIMATIC NET FastConnect glass fiber-optic cables are used to construct optical indoor and outdoor Industrial Ethernet/PROFINET and PROFIBUS networks. Devices with integral optical interface (LC or ST/BFOC connection technology) include optical link modules (OLM) and SCALANCE X Industrial Ethernet switches, for example.

FastConnect glass fiber-optic cables are to be assembled on site using FastConnect FC LC or FC ST/BFOC connectors. Two suitable FC FO Termination Kits are available for this purpose. They enable stripping and "cleaving" of the fiber in the assembled connector, as is familiar from PCF fiber-optic cables. For ST/BFOC connectors, the ST/BFOC coupler can be used to extend existing lines.
