Aerial plant has a lifespan of up to how many years?

The main idea is the typical service life used for planning and budgeting outside plant that runs aerially on poles. Aerial plant sits directly in the weather, so insulation, jackets, and hardware age from sun, moisture, temperature swings, wind, and ice. In standard OSP design practice, the expected life for aerial plant is about 30 years. This duration reflects a practical balance between cost and reliability, recognizing that some components might require attention earlier if conditions are harsh, while others could last longer with good maintenance. A 40-year life is generally longer than what is typical for aerial installations, whereas 20–25 years would be shorter than the standard planning assumption. Therefore, 30 years is the best fit for typical aerial OSP lifespans.
