Optical connector and method of attaching optical fiber cord to optical connector

An optical connector used for attachment of an optical fiber cord comprising an optical fiber, a tension member arranged around the optical fiber, and a sheath, wherein the optical connector comprises:

• a plug part having a built-in optical fiber-containing capillary provided at the front, the plug part including a mechanical splicing portion capable of allowing an optical fiber to be inserted from the rear so as to be fixed therein;
• a caulking stand that allows the optical fiber cord to be inserted;
• a caulking ring provided outside the caulking stand so as to hold the tension member between the caulking ring and the caulking stand, the caulking ring being capable of radially contracting the caulking stand so as to hold the sheath;
• and
• a coupling body provided behind the plug part, the coupling body accommodating the caulking stand and the caulking ring.
