How fast should optical cable stripping be performed

Optical fiber coatings can be stripped in as little as 5–8 seconds per fiber using modern automated or heated handheld strippers.

Manual and Handheld Stripping

Manual fiber strippers are precision tools designed to remove coatings from optical fibers without damaging the glass core. Typical coated fibers have a 125 µm glass diameter with coatings around 250 µm. Stripping a standard 30–40 mm length manually can take several seconds per fiber, depending on the operator's skill and the type of coating (acrylate, silicone, or polyimide) being removed . Handheld battery-powered strippers with integrated heating elements, such as AFL's Precision Strip, can strip 900 µm coated fibers in 5–8 seconds, requiring minimal force and reducing the risk of fiber damage .

Semi-Automated and Automated Stripping

Semi-automatic machines, like Komax FiberOptic 7010 or FiberStrip 7030, are designed for high repeatability and efficiency. These systems can handle fibers with coatings from 125/250 µm up to 125/900 µm and strip lengths ranging from 3 mm to 60 mm . Automated systems are particularly useful in production environments, where multiple fibers need to be stripped quickly and consistently, significantly increasing throughput compared to manual methods.

Factors Affecting Stripping Speed

1. Coating Type and Thickness: Thicker or multi-layer coatings require more time or higher heat settings to remove cleanly .
2. Fiber Age and Condition: Field-aged fibers may have coatings that are slightly harder to strip, but studies show that properly designed strippers can handle aged fibers without reliability issues .
3. Tool Type: Mechanical, thermal, or non-contact strippers vary in speed. Heated or plasma-assisted strippers are generally faster than purely mechanical ones .
4. Operator Skill: Manual stripping speed depends on experience, while automated systems provide consistent high-speed performance regardless of operator skill .

Practical Considerations

• For field work, handheld battery-powered strippers are preferred for speed and portability.
• In production or laboratory settings, semi-automatic or fully automated machines maximize throughput and reduce the risk of fiber damage.
• Typical strip lengths should not exceed 50 mm at a time to avoid fiber damage . In summary, modern fiber stripping tools allow rapid, precise removal of coatings, with high-quality automated or heated handheld strippers achieving stripping times as fast as 5–8 seconds per fiber, making them suitable for both field and production applications .
