Figure 42: 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 43 .
NOTE
Kinks and sharp bends can destroy or impair the cable’s ability to convey light pulses accurately from one end of the
cable to the other. Use care in dressing the optical fiber cables: provide satisfactory strain relief to support the cable
and maintain an adequate bend radius at all cable turns, particularly where the cable connects to the I/O module.
