∎ Cleaving tools: These tools score and snap the fiber, creating a smooth and perpendicular end face for optimal light transmission. They come in various types, including manual cleavers, automated cleavers, and fusion splicers with integrated cleaving functions. ∎ Diamond scribers: A fine diamond tip can score the fiber, followed by gentle pulling to achieve a clean break. This method is less precise than using dedicated cleaving tools but can be useful in field applications. ∎ Laser cleaving: High-powered lasers can vaporize a small portion of the fiber, creating a clean and precise cleaved end. This method is often used in automated production lines for its speed and accuracy.
