Fiber Optic Cable

Fiber optic cable must be handled carefully during installation. Every cable has a minimum bend
radius, for example, and fibers will be damaged if the cables are bent too sharply. It is also important
not to stretch the cable during installation. We recommend that the bend radius for fiber optic cable
equal 2 inches (5.08 cm) minimum for each 90-degree turn as shown in
