Install Fibre-Optic Cables

Rule 3
Route fibre-optic cables away from groups of other cables where they may be
stretched by the weight of metal cable bundles, as fibre-optic cables are quite
flexible.
stretched by the weight of metal cable bundles, as fibre-optic cables are quite
flexible.
Rule 4
Avoid bending fibre-optic cables to a radius smaller than 1-1/2 inches (4 cm), to
prevent mechanical stress on the cables, as they are rather delicate. Plan your
use of cable ties to avoid crimping the cable or creating a fixed stress point
where, at a later time, movement of the cable causes it to exceed the minimum
bend radius.

Rule 5
Ensure fibre-optic cables are not pressed against any sheet metal edges by
subsequently installed cables.

Recommendation
In some such systems it may be required to run fibre-optic cables with the
input/output cables, such as in the cable slack manager or under a raised floor.
In these situations, protect the cable by running it in a dedicated area if
possible. When you must run the cable with other cabling, protect it by running it
through flexible conduit.
