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. So, how often. The longevity of indoor fiber optic cables depends on several key factors, including the type of cable, installation environment, and usage conditions. But ask any veteran network engineer, and they will tell you a different story. 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. 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.

This paper reviews the sensing principle, structural design, and temperature measurement performance of fiber-optic high-temperature sensors, as well as recent significant progress in the transition of sensing solutions from glass to crystal fiber. Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. Unlike traditional electrical temperature sensors (e., thermocouples, RTDs), fiber optic sensors offer significant advantages such as immunity to electromagnetic interference. Optical fiber-based temperature sensors have played a crucial role in this decade to detect high fever and tackle COVID-19-like pandemics.
