Key Points for Optical Cable Stripping

Optical cable stripping can be performed using mechanical, thermal, chemical, or automated methods, each designed to safely remove protective coatings without damaging the delicate fiber core.Mechanical StrippingMechanical stripping is the most common method, using precision hand tools or scissors to remove the outer jacket, buffer, and coating layers. Tools such as fiber strippers have sharp-edged slots sized for specific coating diameters, allowing controlled removal of the jacket, primary, or secondary coatings without nicking the glass fiber . Multi-layer cables require progressive stripping: first the jacket, then aramid yarns, and finally the buffer coating, ensuring each layer is removed carefully . Proper maintenance of the blades is essential to maintain clean, straight cuts.Thermal StrippingThermal stripping uses heat to soften the polymer coatings, making them easier to remove. Devices like the AUTOSTRIPPER 2™ employ heated air to strip acrylate coatings quickly and cleanly, suitable for variable window lengths and high-strength fibers . This method reduces the risk of mechanical damage and is often used in industrial or high-volume applications.Chemical StrippingChemical stripping involves applying solvents to dissolve the polymer coatings. While effective for certain coatings, it requires careful handling of chemicals and thorough cleaning afterward to prevent residue on the fiber, which could affect splicing or connectorization . This method is less common in fieldwork due to safety and environmental concerns.Automated StrippingAutomated systems, such as the AUTOPREP 2™, combine stripping, cleaning, and cleaving in a single process. These machines are designed for high-speed, consistent preparation of fibers, particularly in industrial settings where precision and repeatability are critical . Automated tools minimize operator error and ensure uniform stripping lengths.Best PracticesInspection: Always inspect stripped fibers under magnification to detect nicks or scratches that could compromise signal integrity .Cleaning: Use isopropyl alcohol and lint-free wipes to remove debris from the exposed fiber .Safety: Wear protective eyewear to prevent injury from flying debris during stripping .Layer Awareness: Understand the cable structure, including jacket, strength members, buffer, cladding, and core, to select the appropriate stripping method . By selecting the appropriate method and tool for the fiber type and coating, technicians can achieve clean, precise stripping, ensuring optimal performance and longevity of fiber optic networks.
