technical field

The utility model relates to the technical field of optical fiber processing, in particular to an optical fiber cutting device.

Background technique

When optical fibers are installed or connected, the optical fibers need to be stripped. For example, in the production of optical connectors, the optical fibers need to be stripped and then cured in the ceramic ferrule. The usual practice is to first strip off the jacket layer on the surface of the optical fiber to expose the coated optical fiber, and strip off the coating on the front end of the coated optical fiber to form a bare optical fiber segment. Therefore, when cutting, it is relatively troublesome to cut the outer protective layer of the optical fiber, and due to different installation requirements, the lengths to be stripped are different, and the outer diameters of the optical fibers used are also different.
