Reusing fiber-optic cable
Note
If you insert previously used fiber-optic cable into the plug adapter, you must shorten both fiber-
optic cores by the amount of the curved lengths and reinstall the simplex connectors.
This will prevent any attenuation losses caused by repeatedly bent, heavily stressed portions
of the fiber-optic duplex core.
Inserting the fiber-optic cables into the IM 467 FO
Insert the fiber-optic cable with the mounted plug adapters into the IM 467 FO. Fold the
protruding plug grip upward.
Make sure that it is correctly positioned: The transmitter fiber-optic cable is plugged into the
receiver socket, and the receiver fiber-optic cable is inserted into the transmitter 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 blanking plugs (the plugs are already in place when the IM 467
FO is delivered).
Do not look directly into the opening of the optical sender diodes.
The emitted light beam could damage your eyes.

Plug-in adapter for the IM 467 FO
Snap the two simplex connectors closed together such that you get a "duplex connector".
Tip: Cut the lower cable approx. 10 mm shorter than the upper one to achieve better cable
routing in the cable duct of the IM 467 FO.
Max. 30 mm bending radius
