that the bend radius for fiber optic cable equal at least 5 cm (2 in) for each 90-degree turn as shown in
Figure 11.
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 13 on page 28 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
complete list of supported cable lengths.
Refer to Extreme Hardware/Software Compatibility and Recommendation Matrices
types that are compatible with your equipment.
