Abstract
A ferule structure for receiving an optical fiber composed of a core and a sheathing for covering the core exclusive of its end includes a core holder for holding the core; a sheath holder for holding the sheathing, communicating with the core holder and being located on an outer wall of the sheathing; and a metallic cylinder member for fixing the sheathing. The metallic member is formed integrally to the sheathing holder. The sheathing holder has a window from which the metallic cylinder member is partially exposed. The metallic cylinder member is caulked through the window so that the sheathing is compressed toward the core. In this configuration, the optical fiber and ferule can be surely secured to each other without using an adhesive.

A ferule structure for receiving a fiber composed of a core and a sheathing for covering the core exclusive of its end, comprising
- a core holder for holding said core;
- a sheathing holder for holding said sheathing, said sheathing holder communicating with said core holder and being located on an outer wall of said sheathing;
- and
- a metallic cylinder member for fixing said sheathing, said metallic member being formed integrally to said sheathing holder, wherein said sheathing holder has a window from which said metallic cylinder member is partially exposed;
- and said metallic cylinder member is caulked through the window so that said sheathing is compressed toward said core.
An assembly of an optical fiber and a ferule comprising:
- an optical fiber composed of a core and a sheathing covering the core exclusive of its end;
- and
- a ferule for receiving said optical fiber, said ferule including a core holder for holding said core, a sheathing holder for holding said sheathing, said sheathing holder communicating with said core holder and being located on an outer wall of said sheathing;
- and a metallic cylinder member for fixing said sheathing, said metallic member being formed integrally to said sheathing holder, wherein said sheathing holder has a window from which said metallic cylinder member is partially exposed and said metallic cylinder member is caulked through the window so that said sheathing is compressed toward said core.
