Professional Optical Cable Stripping Tools

Optical cable stripping requires precision tools such as mechanical strippers, hot knives, and specialized cable slitting devices to safely remove coatings, buffers, and jackets without damaging the fiber.

Types of Fiber Stripping Tools

Mechanical Fiber Strippers: These are handheld tools designed to remove polymer coatings from optical fibers, typically 30–40 mm in length, exposing the bare glass for splicing or connectorization. They are available for standard telecommunication fibers (125 µm cladding, 250 µm coating) and specialty fibers with thinner coatings. Some strippers also handle tight buffers (900 µm) and larger cable jackets. Mechanical strippers often include fiber guides and matched blades to ensure precise, nick-free stripping . Thermal and Hot Knife Strippers: Tools like the Industrial Fiber Optics Heavy Duty Fiber Optic Hot Knife use heat to remove coatings cleanly, especially useful for thicker or specialty fibers. These tools minimize mechanical stress on the fiber and are suitable for high-volume or industrial applications . Cable Jacket and Loose Tube Strippers: For larger cables, tools such as the Jonard CST-4000 or ACS Armored Cable Slitter allow longitudinal, spiral, or circular cuts to remove outer jackets, aramid yarn, or armor. Adjustable blade depth ensures the fiber inside is not damaged. Coaxial and loose tube strippers can handle diameters from 0–14 mm, with transverse and longitudinal cutting capabilities . Multi-Function Kits: Kits like Thorlabs' TSK1 include multiple blade sets, fiber guides, and jacket strippers in a compact case. They often feature color-coded blades for quick identification and ergonomic handles for secure gripping without microfractures .

Practical Usage Tips

1. Select the correct tool for the fiber type and coating diameter to avoid nicking the glass.
2. Strip in short lengths (typically ≤50 mm) to prevent fiber damage.
3. Clean the fiber after stripping using lint-free wipes and high-purity alcohol or dedicated fiber cleaners.
4. Use grippers or guides to hold the fiber securely during stripping, avoiding wrapping or clamping that can create microfractures .
5. Adjust blade depth for cable jackets or armored fibers to ensure precise cuts without harming the internal fibers .

Summary

For effective optical cable stripping, professionals rely on a combination of mechanical strippers, thermal tools, and specialized cable slitting devices, often integrated into multi-function kits. Choosing the right tool depends on fiber diameter, coating type, and cable construction, while proper handling and cleaning ensure optimal fiber performance and longevity .
