Polyimide coated multimode fiber
Our high temperature polyimide coated multimode fiber is ideal for fiber optic sensing applications such as distributed temperature sensing.
With operating temperatures up to 300 degrees C and excellent chemical durability, polyimide coated fibers can be used in harsh environments and applications such as oil & gas and avionics.
The fiber is also available with hermetic carbon.
