Figure 5: Properly installed and bundled cable
Fiber Optic Cable
Fiber optic cable must be treated gently 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 equals 2-inch
(5.08 cm) minimum for each 90 degree turn as shown in
Figure 6 .
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.
