Site Preparation
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
Table 19 shows cable media types and maximum distances that support reliable transmission in
accordance with international standards except where noted.
