7.3.9 Special cables
Special cables
In addition to the preferred SIMATIC NET FO cable types described in the IK PI catalog,
there are numerous special cables and installation accessories available. Listing all would
exceed the scope of both the catalog and this manual.
The technical specifications of the SIMATIC NET bus components contains the SIMATIC
NET FO cables used as standard cables for connections and also lists additional fiber types
that can be used.
Note
Remember that the distances that can be covered change if you use fibers with a different
core diameter or attenuation properties from those listed as standard in the operating
instructions.
Fiber types
In addition to the preferred SIMATIC NET FO cable types, the following fiber types are often
used:
● 10 μm fiber
This singlemode fiber is used for transmission over extremely long distances. The use of
this singlemode fiber requires special, highquality transmitter and receiver elements and
connectors. In conjunction with OLM/G111300 or OLM/G121300, distances up to 15 km
can be spanned.
Cable design
For special applications, numerous variations in the cable structure are available, for
example:
● Bundled cords (cables with hollow cords capable of accommodating several fibers)
● Hybrid cable with fibers and copper conductors in one jacket
● Certified cables, for example for use on ships
