1.6.3 Optical fibre waveguide connection
The following types transmission media can be used for
the PROFIBUS:
– cable transmission (screened two-core cable)
– optical fibre waveguide (plastic and glass fibre)
We recommend the optical fibre waveguide technology
for transmission in environments subject to strong inter-
ference as well as for extending the transmission range
when high baud rates are used.
The optical fibre waveguide technology offers the fol-
lowing advantages:
– higher EMC, ESD protection thanks to the optical
transmission of signals
– protection against lightning
– potential isolation of the individual DP slaves (equali-
zing currents cannot flow via the cable screening)
The PROFIBUS DP interface of the node has been de-
signed in accordance with specification EN 50170 vol-
ume 2 and thereby supports the control of network
components for optical fibre waveguides.
Example of optical fibre waveguide network compo-
nents:
– Siemens optical link module (OLM) for PROFIBUS plus
– Siemens optical link plug (OLP) for PROFIBUS
