The lifespan of fiber optic cables can vary depending on factors such as installation quality, environmental conditions, and maintenance practices. In general, well-installed and properly maintained fiber optic cables can last for several decades.
Some estimates suggest that the glass fibers themselves have a lifespan of around 25 to 30 years. However, the lifespan of the overall fiber optic infrastructure, including connectors, splices, and protective sheathing, may be longer with regular maintenance and occasional upgrades.
It's worth noting that fiber optic technology continues to evolve, and newer generations of fiber optic cables may offer improved performance and longevity compared to older versions. Regular inspections, maintenance, and upgrades can help extend the lifespan of fiber optic cables and ensure reliable performance over time.
