These fibers are designed for distributed temperature sensing applications. In the mid-temperature range up to 125 ºC for up to 20 years, select Geo50™ SA. When temperature requirements are higher, up to 300 ºC, choose Geo50. The fibers are protected against moisture and hydrogen ingression across the temperature range. They are resistant to water and chemicals, and cushioned for deployment and service in harsh environments.
