Figure 11: 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 12.

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.
