Fusion splicing is a popular method of connecting butterfly-shaped optical fiber cables. The two fiber cables are stripped of their protective coatings, and their bare ends are aligned and then fused together using a fusion. The utility model discloses a prefabricated end butterfly-shaped optical cable assembly movable connector, which comprises: outer body, interior body, ceramic lock pin, supporting tube, tail cover and optical cable, inside the head of interior body inserts outer body, the ceramic lock pin has lock. The utility model belongs to the technical field of communication equipment, in particular to a prefabricated end butterfly-shaped optical cable connector, which comprises an inner sheath, one end of the inner sheath is sleeved with an outer sheath in a sliding way, a sliding groove corresponding. Butterfly-shaped optical fiber cables, also known as ribbon fiber optic cables, are a type of fiber optic cable that contains multiple fibers within a single flat ribbon. This design allows for easy installation and termination, as multiple fibers can be spliced or connected at once. They are called butterfly-shaped due to their unique design, which features a flat shape with two parallel fiber ribbons running down the center.
