8.3.3 Connecting a Fiber-Optic Cable to the IM 467 FO
Accessories Required
• Pack of Simplex connectors and polishing sets (6GK1901-0FB00-0AA0)
• Pack of plug-in adapters (6ES7195-1BE00-0XA0)
Installing Connectors
1. Remove approximately 30 cm of the sheath of the fiber-optic duplex cable.
2. Install the fiber-optic duplex cable with the associated Simplex connectors. You
can find a detailed description of Simplex connectors in the ”SIMATIC NET
PROFIBUS Networks” manual.
TIP: Close the two Simplex connectors together rather than separately to obtain
a Duplex connector. This ensures a more secure position in the plug-in adapter.
IMPORTANT: The polished surface of the plastic fibers must be absolutely
smooth and even. The plastic sheath must not stick out or be cut unevenly. If
this is not the case, considerable attenuation of the light signal via the fiber-optic
cable may occur.
3. Place the Simplex connectors in the plug-in adapter for the IM 467 FO and the
fiber-optic cable in the cable guides provided. Insert the plug-in adapter until
you hear the sides clearly latch into position.
Make sure when you insert the plugs in the plug-in adapter that the sender is
always at the top and the receiver is underneath.

the IM 467 FO
Put the 2 Simplex connectors
together to make
one duplex connector.
Tip: Cut the lower cable approx. 10 mm shorter
than the upper one to achieve better cable routing
in the cable channel of the IM 467 FO.
