Automatic Cleaver for Large Core Fibers

Large-Diameter Cleaver

Fiber cleavers that can be used to process large-core fibers that are between 125 µm and 550 µm in diameter are available for round and non-round fibers.

There are two quality features to note during cleaving: the flat end surface of the fiber and a defined, reproducible cleave angle.

ProCleave LD (125 - 550 µm)

The ProCleave LD (Large Diameter) is a cleaving tool that was specifically designed for use in the laboratory and production for optical fibers with a diameter of up to 550 µm. It generates cleaves with very flat end faces at an angle that deviates only very slightly – typically <0.5° – from the ideal angle of 90°. It has an integrated backstop for double-clad fibers or structured fibers. The ProCleave is an ideal addition to the splicing units FITEL S178LDF and FITEL S183PMII.

The fiber is placed under very finely adjustable, defined tensile stress and then scratched using a diamond blade. When the diamond touches the fiber, the fiber breaks automatically along the stress distribution in the fiber. The ProCleave can be operated by battery or using a power supply.
