Fiber Optic Cleaver Cutters
In the field of fiber optics, it is very necessary to use fiber optic cables with clean and smooth end face. The fiber optic cleaver is a crucial tools for low-loss and low-reflectance fiber optic splices or terminations, especially when using the pre-polished connectors with internal splices. The fiber cleaver usually work in conjunction with fusion splicers to do optimum splicing jobs, and is the key to quality connectors and splices.
What Is Cleaving and Fiber Cleaver?
Cleaving is the process by which an optical fiber is “cut” or precisely broken for termination or splicing. Just like cutting glass plate, fiber is cut by scoring or scratching the surface and applying stress so the glass breaks in a smooth manner 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.
A fiber cleaver is a tool that holds the fiber under low tension, scores the surface at the proper location, then applies greater tension until the fiber breaks. Good cleavers are automatic and produce consistent results, irrespective of the operator. With good fiber cleavers, you only need to clamp the fiber into the cleaver and operate its controls, then fiberglass is cleaved automatically. However, some cleavers are less automated and require operators to exert force manually to cut the fiber cable, which makes it difficult to predict and control the force. The good cleavers are called as precision cleavers, while the less automated ones are called as cheap or scribe cleavers, which will be introduced in the next part.
