SIMATIC NET PCF fiber-optic conductors are used to construct optical indoor and outdoor Ethernet/PROFINET networks. They are easy to assemble on-site with 2 x 2 RJ connectors. The maximum cable length between two Ethernet/PROFINET devices is 100 m.

Ethernet/PROFINET devices with integral optical interface (SC RJ connection system) are e.g. SCALANCE X-200P IRT, ET200S.
