摘要： A method of splicing an optical fiber of the invention splices a first optical fiber cable and an optical fiber in a splicing box, the first optical fiber cable is a drop cable or an indoor cable, the optical fiber is drawn from a second optical fiber cable, the method splices a terminal of the first optical fiber cable and the optical fiber. The method includes: sliding a unit base holding an extended-optical-fiber-attached splice along a rail in a direction in which the unit base approaches a grasper; thereby inserting an inserted optical fiber grasped by the grasper between halved elements of a mechanical splice; and splicing the inserted optical fiber and an extended optical fiber by butt-jointing an end of the inserted optical fiber to the extended optical fiber.

摘要： A mechanical splice unit of the invention includes: a mechanical splice having an optical fiber guide groove that is formed at matching surfaces of both a base and a lid in a two-part-divided structure, the mechanical splice being capable of grasping a first optical fiber at one end side of the lid; and an optical fiber splice auxiliary tool used for splice of the first optical fiber that is grasped by the mechanical splice, wherein the optical fiber splice auxiliary tool includes: a mechanical splice grasping portion that holds the mechanical splice; and a guided portion that is slidable along a guide portion formed at a splicing tool to which a second optical fiber to be spliced to the first optical fiber is fixed.
