SIMATIC NET PROFIBUS Plastic Fiber Optic Installation Instructions for BFOC Connectors

Marking of the SIMATIC NET PROFIBUS plastic fiber-optic standard cable

To help you connect up the cable correctly, the standard cable has arrow markings on the orange cord.

This helps to make sure that you attach one end of a cord to the transmitter and the other to a receiver (crossed over cords).

First connect the orange cord:

∙If the arrow on the orange cord is pointing out of the cable, connect this cord to the receiver. The receiver is identified by an arrow pointing into a circle.

∙If the arrow on the orange cord points into the cable (picture), connect this cord to the transmitter. The transmitter is identified by an arrow pointing out of a circle.

The black cord is then connected to the free socket of the same FO interface.
