that the bend radius for fiber optic cable equal 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
on page 45 shows one example of cable media types and maximum distances that support
reliable transmission in accordance with international standards (except where noted). Refer to
Networks Pluggable Transceivers Installation Guide
for descriptions of optics and cables, as well as a
complete list of supported cable lengths.
Refer to
Extreme Hardware/Software Compatibility and Recommendation Matrices
for a list of the cable
types that are compatible with your equipment.
