Abstract:
1. A method of butting and connecting a first optical fiber and a second optical fiber in an optical connector, the method comprising: placing the optical connector that holds the first optical fiber in an optical fiber connection tool, the first optical fiber having a front end face beveled relative to a plane perpendicular to an optical fiber axis direction, the optical fiber connection tool comprising a holder support base that supports the optical connector thereon and an optical fiber holder that holds the second optical fiber therein, the holder support base having a guide part that guides the optical fiber holder in a direction approaching the optical connector; mounting the optical fiber holder that holds the second optical fiber therein, on a holder mounting base of an angled fiber optic cleaver; beveling a front end face of the second optical fiber by making a scratch on a side facing the holder mounting base of the cleaver while twisting the second optical fiber along a rotation direction of the axis; transferring the optical fiber holder that fixes the second optical fiber having a beveled front end face to the holder support base; and moving the optical fiber holder toward the optical connector along the guide part, and butting and connecting the beveled front end face of the second optical fiber to the front end face of the first optical fiber such that their bevel directions are aligned, wherein a bevel angle and a phase of the first optical fiber are predetermined so as to match the cleaved front end face of the second optical fiber.
