GEO50 is designed for distributed temperature sensing applications and will function in the high temperature range up to 300 ºC for up to 20 years. The fiber is protected against moisture and hydrogen ingression across the temperature range.
The fiber’s carbon/polyimide coating help sensure survivability and functionality when deployed and put in service in harsh environments.
