If installed and protected correctly against technical and environmental conditions, they can last: 25–50 years (outdoor plant infrastructure, long-haul wiring) 15–30 years (indoor building wiring systems) 10–20 years (FTTH plant drop. From FTTH optics to industrial applications, backbone transmission, and cloud data centers, fiber cables can last for decades under appropriate installation and handling. The lifecycle of fiber optic products involves multiple stages, from initial design and manufacturing to deployment, maintenance, and eventual upgrades or replacement. However, the actual replacement frequency depends on several factors, including environmental conditions, usage, and technological advancements. The high-quality materials used in their construction make them resistant to corrosion, extreme temperatures, and wear and tear, allowing them to maintain their performance over a long period of.
