Mechanical splice unit, mechanical splicing tool, and optical fiber splicing method

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.
