Carbon coated singlemode fiber with polyimide

Fibertronix line of carbon coated fibers offer excellent protection against indiffusion of hydrogen and the formation of hydroxyles.

In combination with high temperature polyimide coating, these fibers are the preferred choice for e.g. sensing applications in harsh environments.

Hermetically coated fibers are also available with standard acrylate, high temperature acrylate and other coatings.
