that the bend radius for fiber optic cables is equal to at least 5 cm (2 in) for each
90-degree turn as shown in
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.

Cable Distances and Types
Table 11 shows one example of cable media types and maximum distances that support
reliable transmission in accordance with international standards (except where noted).
Refer to the
