Cleaver is translated as cleaver and cleaver. A cleaver is a fiber cutting tool for cutting glass fibers. In this context, it is also referred to as a fiber cleaver or cleaving tool
. Glass is cut by scratching and breaking. When splicing optical fib ers, the break must be perpendicular to the fiber axis and exceptionally smooth so that the reflection and attenuation
in the splice is as low as possible. For this cutting there are special tools called cleavers.
Cleavers can look like pliers or as a small cutting station with a clamping device. They use diamonds, sapphires or tungsten carbide as cutting tools. The fiber optic under tension is scored with the cutting tool and then broken. The broken area is extremely smooth and has the desired surface.
