In this context, the main idea is the expected service life that engineers use for outdoor cables based on environmental risk. For locations with low to moderate environmental risk, OSP cables are designed with a planning life of up to 30 years. This figure reflects typical performance of outdoor-rated jackets and protection under normal outdoor conditions, considering factors like UV exposure, moisture, temperature cycling, and mechanical loads. It’s not a guaranteed lifespan; actual longevity depends on installation quality, maintenance, and any unusual hazards along the route. If environmental risk were higher, designers would typically assume a shorter life or add protective measures; in lower-risk environments, 30 years is the standard planning horizon.
