8.2.6.3 Connecting the bus cable with the fiber-optic cable system
For applications in an environment which is subjected to a high level of
interference, fiber-optic cables can also be used with the PROFIBUS-DP.
The specification of fiber-optic-cable transmission is defined in
PROFIBUS guideline No. 2.021.
For connecting fiber-optic cables to the CBP, an OLP (Optical Link Plug)
can be used which provides integrated conversion of the RS485 signals
in fiber-optic cables and vice versa.
With the optical link plugs (OLPs), optical PROFIBUS networks in ring
form can easily be created (single-fiber ring with plastic fiber-optic
cables).

Fig. 8.2-15 Example of a system configuration with OLPs
The OLP can be directly plugged into the 9-pole SUB-D socket of the
CBP. Power is supplied to the OLP via the 9-pole SUB-D connector of
the CBP.
The transmission reliability of PROFIBUS networks is greatly increased
by using fiber-optic cable instead of twisted two-wire cable. As a result,
the bus is insensitive to interference from electromagnetic influences or
overvoltages.
Considerable cost savings are achieved by using plastic fiber-optic
cables which are also easy to fit. Additional grounding is no longer
necessary either.
