This optical fiber is designed for Distributed Temperature Sensing (DTS) and communications in applications where continuous exposure to temperatures up to 293 ºC for long durations is possible (~ up to 20 years, performance and reliability will vary depending on installation environment. Consult OFS for guidance). The table below provides more information on life expectancy in various high temperature use cases.
