F18961-02
GEO50 SA Geophysical Graded-Index Optical Fiber
GEO50 SA is designed for distributed temperature sensing applications and will function in the mid-temperature range up to 125 ºC for up to 20 years. The fiber is protected against moisture and hydrogen ingression across the temperature range.
The fiber’s high-temperature, silicone/acrylate coating makes it resistant to water and chemicals, and cushions it for deployment and service in harsh environments.
