Besides shielding twisted-pair copper wires, PROFIBUS can also use optical fiber for transmission in
an electromagnetic interference environment to increase the high-speed transmission distance there
are two kinds of fiber optical conductors, one is low-cost plastic fiber conductor, used distance is less
than 50 meters, the other is glass fiber conductor, and used distance is less than 1 kM.
