Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables
away from sharp objects.
When fiber optic cables are routed, the excess of the cables must be coiled around
special devices, such as a fiber coiler.
An unarmored fiber optic cable must be bound using binding straps. If a fiber optic patch
cord needs to be secured in a cabinet or a piece of equipment, use binding straps to bind
it and then use cable ties to secure the binding straps to the cabinet or equipment. Ensure
that the fiber optic cables can flexibly move in the cable ties. Do not bend the fiber optic
cables sharply. The following figure shows how to bind the fiber optic cables correctly.
Figure 9-4 Binding fiber optic cables
When coiling fiber optic cables, apply even strength. Do not bend the cables with force.
Vacant optical connectors must be covered with dustproof caps.
Fiber optic cables cannot be squeezed by the cabinet door when routed through the
cabinet, as shown in Figure
