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.

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.
