    Fiber Tensile Strength
    The primary coating layer uses UV-resistant material (acrylate), minimizing environmental impact.
    Primary Coating Layer
    The primary coating layer before coloring has a nominal diameter of 245 µm ± 10 µm, after coloring it has a nominal diameter of 250 µm ± 10 µm, using time-resistant ink.
    When splicing, the primary coating layer should be easily removable from the fiber without the need for chemicals and without affecting the fiber.
