Direct buried plant has a lifespan of up to how many years?

Direct buried plant is typically planned for a 30-year service life. This takes into account the exposure of buried cables to soil moisture, temperature cycling, movement, and potential physical stresses, which gradually degrade jackets and insulation. Setting a 30-year planning horizon provides a reasonable balance between material performance and upgrade cycles, and aligns with common OSP design practice. While good conditions and robust construction can push lifespan toward the higher end, 40 years is less typical under normal conditions, and shorter estimates like 20 or 25 years would imply more frequent replacements than standard practice.
