Fiber Optic Cleaving Techniques

摘要

To get good fiber optic splices or terminations, especially when using the pre-polished connectors with internal splices, it is extremely important to cleave the fiber properly. The term "cleave" is somewhat confusing, as is the terminology for the tool that does the job, so let's define our terms and look at how the process is done properly. 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 (called a lip).
