Precision Scoring
✔ Uses a hardened tungsten carbide or diamond blade to create a controlled scratch on the fiber.
✔ Ensures a clean break when the fiber is bent.

Manual Operation
✔ No power required—works by hand pressure.
✔ Commonly used for single-mode (SMF) and multimode (MMF) fibers.

Compatibility
✔ Works with 125µm cladding standard fibers (OS2, OM1-OM5).
✔ Some models support coated fibers (250µm, 900µm).

Common Use Cases
✔ Field fiber splicing (FTTH, telecom).
✔ Preparing fibers for fusion splicing or mechanical connectors.
✔ Emergency repairs when a cleaver isn't available.

How to Use a Fiber Scribe

✔ Strip the fiber coating (using a stripper).
✔ Clean the bare fiber with alcohol.
✔ Score the fiber lightly (~90° angle) with the scribe.
✔ Bend the fiber gently to snap it at the scored point.
✔ Inspect the end face (under a microscope) for smoothness.
