Connection method, connection tool, and connection jig for optical fiber

An optical fiber connection tool comprising:

• a holder support base that supports an optical connector that holds a first optical fiber therein, said first optical fiber having a front end face beveled relative to a surface perpendicular to an optical fiber axis direction;
• an optical fiber holder that holds a second optical fiber therein;
• said holder support base comprising a guide part that guides said optical fiber holder in a direction approaching said optical connector;
• wherein
• said optical fiber holder can be mounted on a holder mounting base of a front end bevel processing tool, so that a front end face of said second optical fiber can be beveled relative to the surface perpendicular to the optical fiber axis direction;
• and
• said optical fiber holder can be moved toward said optical connector along said guide part on said holder support base, such that the beveled front end face of said second optical fiber, can be butted and connected to a front end face of said first optical fiber such that their bevel directions are aligned.

A method of butting and connecting a first optical fiber and a second optical fiber in an optical connector, said method comprising:

• supporting an optical connector that holds said first optical fiber therein on a holder support base, said first optical fiber having a front end face beveled relative to a surface perpendicular to an optical fiber axis direction;
• mounting an optical fiber holder that fixes said second optical fiber thereon, on a holder mounting base of a front end bevel processing tool;
• processing a front end face of said second optical fiber using said front end bevel processing tool such that a bevel angle and a phase match those of the front end face of said first optical fiber;
• transferring said optical fiber holder to said holder support base while said second optical fiber remains fixed;
• and
• butting and connecting the front end face of said second optical fiber to the front end face of said first optical fiber by moving said optical fiber holder toward said optical connector on said holder support base.

A method of butting and connecting a first optical fiber, with a front end face beveled relative to a surface perpendicular to an optical fiber axis direction, and a second optical fiber in an optical connector, said method comprising:

• fixing said optical connector a first position;
• processing a front end face of said second optical fiber such that said end face is beveled relative to the surface perpendicular to the optical fiber axis direction aligned with a bevel angle of said first optical fiber;
• moving said second optical fiber toward said optical connector while maintaining the bevel direction of said second optical fiber such that the front end face of said second optical fiber and the front end face of said first optical fiber match;
• and
• connecting said first optical fiber and second optical fiber such that the bevel direction of the front end face of said second optical fiber and the bevel direction of the front end face of said first optical fiber match.
