Fiber Optic Strippers

Using the right fiber optic stripper and proper technique is essential to remove coatings without nicking or scratching the delicate glass core.

Types of Fiber Optic Strippers

Mechanical Strippers: These are handheld tools with precision-ground notches designed for specific fiber diameters, typically 125 µm cladding with 250 µm coating. They are ideal for standard telecommunication fibers and can also handle specialty fibers with thinner coatings . Thermal Strippers: These use controlled heat to soften the fiber coating, allowing gentle removal without applying excessive force. Adjustable temperature and timing settings help prevent micro-cracks or stress fractures in the fiber . Automated and Plasma-Assisted Strippers: Fully automated devices can perform end or window stripping with minimal contact, even on large-diameter buffers up to 1200 µm. These systems maintain fiber strength and reduce the risk of damage during high-volume or precision applications .

Best Practices to Prevent Fiber Damage

1. Use the Correct Tool: Avoid generic wire strippers or blades, which can create microscopic nicks, scratches, or stress fractures, leading to signal loss or connection failure .
2. Match Fiber Diameter: Ensure the stripper's notch or hole size matches the fiber's coating diameter to avoid over-compression or incomplete stripping .
3. Minimal Force: Apply only the necessary force; thermal or battery-powered strippers reduce manual effort and prevent accidental fiber breakage .
4. Clean and Maintain Tools: After each use, clean stripping notches with a soft brush and isopropyl alcohol to remove residue. Store tools in a protective pouch to prevent blade damage .
5. Avoid Misuse: Never use fiber strippers on copper wires or other materials, as this can damage the precision-ground surfaces .

Additional Tips

• For high-strength splices, select strippers that maintain tensile strength above 20 N .
• In field applications, portable, ergonomic strippers like battery-powered models improve efficiency and reduce hand fatigue .
• For laboratory or production environments, automated plasma-assisted strippers provide consistent, repeatable results with minimal risk of fiber damage . By selecting the appropriate stripper type, following proper handling techniques, and maintaining tools carefully, technicians can maximize fiber integrity, reduce signal loss, and ensure reliable splicing and connector performance.
