What is true about the lifespans of direct buried and aerial plant?

Lifespans for outdoor plant are planned around a long-term horizon, typically about 30 years for both direct-buried and aerial installations. This planning date reflects durable materials, protective construction, and maintenance practices that allow fiber plant to remain functional and upgradeable for several decades. In practice, actual life can vary with environmental factors and maintenance, but the design and budgeting approach commonly uses a 30-year expectation for either burial method. Shorter numbers would imply more frequent replacements and higher lifecycle costs, while a 30-year target keeps planning consistent for both methods when installed and maintained properly.
