The industry standard says Fiber Optic Cable Lifespan should last 25 years. But ask any veteran network engineer, and they will tell you a different story. So, how often. The longevity of fiber optic cabling infrastructure has already exceeded 35 years since the first deployments and we expect the average lifetime will be much longer than 35 years based on the materials, technologies, and manufacturing processes used to produce modern, high quality optical fiber and. With proper installation, fibre optic cables have a service life of around 25 years, but in practice, can perform for far longer. A process called 'stress corrosion' is the biggest threat to the longevity of fibre cabling. Even with the most skillful and diligent installation, commercially-produced. The degradation of optical cables over time is influenced by various environmental and operational factors: Mechanical Stress: Excessive tensile strain during installation or operation can accelerate fiber breakage. This paper summarizes some of the results of extended environmental aging studies of single mode silica glass optical fibers.
