Polyimide coated optical fibers

Our polyimide coated optical fibers can withstand high temperatures up to 250°C in air and up to 300°C in an inert atmosphere. Our unique technology delivers optical fibers with durable black polyimide coating with very low attenuation of below 1 dB/km. ENDUROFIBER polyimide coated optical fibers were experimentally verified to be compliant with majority of the distributed sensing techniques.
