Fiber optic Cleaver

What is a Fiber optic Cleaver?

Cleaving is the process by which an optical fiber is “cut” or precisely broken for termination or splicing. Just like cutting glass plates, fiber is cut by scoring or scratching the surface and applying stress so the glass breaks smoothly along the stress lines created by the scratch. Properly done, the fiber will cleave with a clean surface perpendicular to the length of the fiber, with no protruding glass on either end.

Two Types of Fiber Optic Cleavers

As mentioned before, fiber optic cleavers can be classified into precision cleavers and cheap or scribe cleavers.

Scribe Cleavers

The scribe or manual cleaver, which is cheaper than the precision cleaver, is the most original type of fiber optic cleaver. Scribe cleavers are usually shaped like ballpoint pens with diamond-tipped wedges or come in the form of tile squares. The scribe has a hard and sharp tip, generally made of carbide or diamond, to scratch the fiber manually. Then the operator pulls the fiber to break it. Since the breaking process is under manual control, it is hard to control the force, which makes the cleaving less accurate and precise. That’s why most technicians shy away from these cheap cleavers.

Precision Cleavers

As the name implies, precision cleavers can do a precise cleaving job compared to scribe cleavers. A precision cleaver uses a diamond or tungsten wheel/blade to provide the nick in the fiber. Tension is then applied to the fiber to create the cleaved end face. The advantage of precision cleavers is that they can produce repeatable results through thousands of cleaves by simply rotating the wheel/blade accordingly. Although they are more costly than scribe cleavers, precision cleavers can cut multiple fibers with increasing speed, efficiency, and accuracy. As the fusion splicers became popular, precision cleavers were developed to support various splicing works. Precision cleavers are deal for fusion splicing standard 125/250um & 125/900um fibers and preparing fiber for various pre-polished connectors.
