Fujikura PCS-100 Polyimide Coating Stripper

PCS-100 Polyimide Coating Stripper

Polyimide coated optical fiber are now widely used in the oil and gas and medical industries. The polyimide coating has superior heat and chemical resistance to conventional UV curable coating material, but the coating requires additional care to remove. Dangerous chemical stripping using hot sulfuric acid or burning the coating off are common methods to strip the fiber due to the thin coating and strong coating adhesion to the fiber cladding. AFL's PCS-100 Polyimide Fiber Coating Stripper is the first tool that uses a mechanical stripping method, providing a safe, consistent and quick stripping solution.


Quick stripping – A precision blade is applied to the fiber with specific tension and the coating is precisely planed along the fiber automatically. The precision of the process ensures minimal damage to the fiber and therfore high strength. The process requires less time than the conventional methods of acid or heat. For a 125 µm fiber, 4 stripping passes at 90º rotational positions are typically required, and complete stripping is accomplished within 25 seconds. Larger fiber sizes require more stripping passes (at smaller rotational angle increments). The use of the blade results in a faceted / tapered coating edge that is ideal for subsequent recoating as the conical tapered coating edge will not trap an air pocket when the recoating compound is injected into the recoater mold.

Window stripping – The stripping process of the PCS-100 results in a window stripped region. For splicing or other similar needs the stripped area may be cleaved to length.  For window stripping applications, the software has recently been enhanced to offer a tapered coating edge at both ends of the window.

Other coating types – The PCS-100 is capable of high strength stripping of other fiber coatings such as acrylate and gold, Recent upgrades also offer capability to strip carbon/polimide coated fiber.

Safe, high quality stripping – Because hot acid is not used, the operation is much safer. In addition, the fiber quality degradation is kept at a minimum as the glass surface is not damaged by oxidization of the coating during burning or arcing.

Flexible – Many parameters, such as the razor blade position and stroke, and fiber rotation angle are all adjustable for various fiber sizes and coating materials.
