● Use plenum-rated cable when it is necessary for safety and fire rating requirements. Consult your
local building codes to determine when it is appropriate to use plenum-rated cable, or refer to IEC
standard 850.

Figure 66: Properly Installed and Bundled Cable
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 Figure 67.
