SIMATIC NET plastic and PCF fiber-optic cables are used together with OLM/P for establishing optical PROFIBUS networks or for optical linking of segments using RS 485 technology in indoor and outdoor applications.

Plastic fiber-optic cables and segmented PCF fiber-optic cables can be assembled on-site with 2 x 2 BFOC connectors. The maximum cable length between two OLM/P is 80 m.

Longer cable lengths up to 400 m can be achieved using PCF fiber-optic cables. These cables are also available preassembled with 4 BFOC connectors.
