The function of fiber optic cable stripper

A fiber optic cable stripper is a precision tool used to remove protective coatings from optical fibers without damaging the delicate glass core.A fiber optic cable stripper is specifically designed to remove the polymer coatings and jackets from optical fibers, exposing the bare glass for tasks such as splicing, connector termination, or in-line splicing . Unlike standard wire strippers used for copper cables, fiber strippers must operate with micron-level precision to avoid nicking or scratching the fiber, which could lead to signal loss or connection failure .Structure and FunctionOptical fibers typically have multiple layers: an outer jacket, strength members (like aramid yarn), a buffer coating, and the acrylate coating directly protecting the glass core . Fiber strippers are engineered to remove these coatings cleanly, often from diameters of 250 µm or 900 µm down to the 125 µm glass cladding . The tool usually has high-precision cavities or slots sized for different layers, allowing the user to strip the outer jacket, primary coating, or secondary coating without damaging the fiber .Types of Fiber StrippersMechanical handheld strippers: Use sharp blades to cut and remove coatings manually .Thermo-mechanical strippers: Apply heat to soften the coating before removal, reducing the risk of fiber damage .Non-contact methods: Include hot air or laser ablation for specialized applications .Chemical strippers: Use solvents or acids to dissolve coatings in controlled environments .Usage and SafetyProper use involves holding the fiber in the correct slot, squeezing the jaws to cut through the coating, and sliding the coating off . Because fiber optic preparation involves very fine materials, safety precautions such as wearing safety glasses and using a labeled sharps container are recommended . In summary, a fiber optic cable stripper is an essential tool for precision fiber preparation, ensuring that the glass core is exposed safely and accurately for high-quality optical connections .
