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).

CAUTION

Do not look directly into the opening of the optical sender diodes.

The emitted light beam could damage your eyes.
