Theoretical Lifespan: 30 to 50 Years. In a perfect vacuum, the silica glass (SiO2) core does not degrade. Manufacturers like Wolontek design cables to remain within attenuation specs for this period. FTTH, or Fibre to the Home, refers to the delivery of optical fibre from a central point directly to individual homes. This infrastructure allows for faster internet speeds and more reliable connections compared to traditional copper wires. FTTH systems use light to transmit data, enabling. 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. Fiber optic cables have a reputation for their prolonged lifespan, low maintenance need, and dependable quality. The glass fiber is not a problem, it's the protection. The statistics indicate that if installed correctly and under acceptable long term load the lifetime of the fiber is very long (>40 years).
