The life expectancy of outside plant fiber, I believe, is 30 years. This
would be an average, so some could fail in 5 years, others in 100. It all
depends on the environmental conditions the fiber is subject to. Water can
infiltrate the sheath over time and if it freezes during winter the water
expands and can cause damage. Eventually, the ice will cut the fiber enough
to cause it to degrade or even fail. Optical Cable Corporation (OCC) might
be a place to ask if you need more specifics.
