Fiber Optic Cleaver Cutters
The high-precision fiber optic cleaver is an essential tool for preparing fiber for fusion or mechanical splicing. Our cleavers feature a long-life, multi-position blade and an automatic fiber scrap collector to deliver clean, fast, and precise cleaves with an end-face angle less than 0.5 degrees. Ensure optimal performance for every splice.

Overview of Fiber Optic Cutters & Cleavers
In fiber optics, the term fiber optic cutter most often refers to a high-precision fiber optic cleaver. While basic cutters exist for snipping cable jackets and strength members, a cleaver is a specialized tool designed to perform a single, critical task: creating a perfectly clean, flat, and perpendicular end-face on an optical fiber. This precise "cleave" is the most important step in preparing a fiber for fusion splicing or mechanical splicing.
A poor cleave with angles, chips, or cracks on the fiber end-face will result in significant signal loss, high back reflection, and a weak splice. Our high-precision cleavers are engineered to deliver consistent, high-quality cleaves every time.
The Importance of a High-Precision Cleave
The quality of a fiber optic connection is directly dependent on the quality of the cleave. A high-precision cleaver works on a "scribe and break" principle. A very sharp, diamond or tungsten carbide blade makes a microscopic scratch on the fiber surface. Tension is then applied, causing the fiber to break smoothly along the scribe, creating a mirror-like finish that is exactly 90 degrees to the fiber axis. This perfect surface is essential for:
- Fusion Splicing: Allows the two fiber ends to be perfectly aligned and melted together with minimal loss.
- Mechanical Splicing: Ensures the fiber ends meet precisely within the index-matching gel for a strong, low-loss connection.
- Field-Installable Connectors: A good cleave is required for terminating fibers with "no-polish" or "splice-on" connectors.
Key Features of Our Fiber Optic Cleavers
Our fiber cleaver tools are designed for efficiency, accuracy, and durability in the field.
-
- Long-Life Rotating Blade: The blade typically has 16 or 24 positions. After a set number of cleaves, the blade can be rotated to a new, sharp position, extending the total blade life to tens of thousands of cleaves before replacement is needed.
- Single-Action Operation: Many models automate the cleaving process. Placing the fiber in the holder and closing the lid performs the scoring and breaking in one smooth motion, improving consistency.
- Universal Fiber Holder: Designed to accommodate various fiber types, including standard 250µm coated fiber, 900µm tight-buffered fiber, and even ribbon fibers on some models.
- Integrated Fiber Scrap Collector: Safely and automatically collects the dangerous sharp fiber offcuts, keeping the work area clean and safe.
Applications in the Field
A high-precision fiber optic cleaver is an indispensable tool for any technician working with optical fiber. Its primary applications include:
- Preparation for fusion and mechanical splicing
- Installation and repair of fiber optic networks
- Terminating fibers in patch panels and termination boxes
- Use in laboratory and manufacturing settings
FAQ (Technical & Product Questions)
1. What is the difference between a fiber cleaver and a fiber stripper?
A fiber stripper is used to remove the protective polymer coating (acrylate) from the optical fiber to expose the bare glass cladding. A fiber cleaver is then used to precisely cut the exposed bare fiber to create a clean end-face for splicing.
2. How long does a cleaver blade last?
A typical high-precision cleaver blade has a very long life, often between 30,000 and 50,000 cleaves. The blade has multiple rotating positions (e.g., 16 or 24). You use one position for a few thousand cleaves and then rotate it to a fresh, sharp edge, greatly extending the tool's usable life before the blade needs to be replaced.
3. Why can't I just use scissors to cut the fiber?
Scissors or simple wire cutters would shatter the glass fiber, creating a jagged, angled, and unusable end-face. This would make it impossible to splice or terminate the fiber, as light would be unable to pass through the connection without massive loss and reflection.
4. What is a "single-action" cleaver?
A single-action or automatic cleaver streamlines the cleaving process. After placing the fiber, a single action, like closing the lid, performs all the necessary steps: clamping the fiber, scoring it with the blade, applying tension, and breaking it. This reduces the chance of operator error and ensures a more consistent cleave quality.
5. Does this cleaver come with a case?
Yes, high-precision instruments like our fiber optic cleavers are typically supplied in a durable, protective case to maintain their calibration and protect them from damage in the field.
