The present invention relates to, a mechanical splice unit, a mechanical splicing tool, and an optical fiber splicing method which butt-joints optical fibers to each other using mechanical splicing.
A mechanical splice is generally configured to include a base having an optical fiber guide groove, a lid covering the base, and a plate spring clamping the base and the lid in a state where the base is matched to the lid. When the optical fibers are optically spliced to each other, in a state where the lid is slightly opened by use of a wedged member, an optical fiber, which is inserted into the optical fiber guide groove (which may be simply referred to as a guide groove hereinbelow) through one end side of the mechanical splice, is butt-jointed to an optical fiber which is inserted into the guide groove through the other end side, on the guide groove.
When optical fiber splicing is carried out by use of the mechanical splice, generally, a mechanical splicing tool is used.
