Reusing Fiber-Optic Cables
Note
If you insert used fiber-optic cables in the plug-in adapter again, you must cut off
the bent lengths of both fiber-optic cable cores and install the Simplex connectors
again.
This avoids any attenuation losses due to parts of the cores of the fiber-optic
duplex cables being bent again and overstressed.
Inserting the Fiber-Optic Cables into the IM 467 FO
Insert the fiber-optic cables and attached plug-in adapters into the IM 467 FO.
Move the protruding handle of the plug-in adapter upwards.
Make sure that it is correctly positioned: The sender fiber-optic cable is plugged
into the receiver socket, and the receiver fiber-optic cable is inserted into the
sender socket of the fiber-optic interface of the IM 467 FO.
If the IM 467 FO is the last node in the fiber-optic network, you must close the
unoccupied fiber-optic cable interface with filler connectors (the connectors are
already in place when the IM 467 FO is delivered).
!Caution
Do not look directly into the opening of the optical sender diodes.
The light beam could damage your eyes.

Bending Radius for the Fiber-Optic Cable
Make sure when you wire the fiber-optic duplex cable cores and insert them into
the plug-in adapter that the permissible bending radius of 30 mm is not violated.
See also the installation guidelines on fiber-optic cables in the SIMATIC NET
PROFIBUS Networks manual.
