The above Guidelines were developed for long-haul
fiber applications, where thousands of kilometers of
fibers are deployed. For these long lengths, it is necessary
to design around the proof stress level. However, for
fibers in short-length applications, where the lengths
tend to be in meters instead of kilometers, one can
exceed the safe-stress guidelines with minimal reliability
risk. This is because the probability of encountering
flaws near the proof stress level is low for these short-
length applications. Therefore, one can expose the fiber
to tighter bends in short-length applications with limited
risk.
