Optical connector, ferrule accommodating component, ferrule accommodating structure, optical coupling structure, and method for replacing optical fiber

An optical connector comprising:

• a plurality of optical fibers including a plurality of central axes extending in a first direction one by one, and arranged in a second direction intersecting the first direction;
• a plurality of ferrules retaining the plurality of optical fibers one by one;
• and
• a ferrule accommodating component including a plurality of accommodating portions arranged in the second direction, the plurality of accommodating portions each being separated by a plurality of side walls arranged in the second direction, the plurality of accommodating portions accommodating the plurality of ferrules one by one,
• wherein each of the plurality of optical fibers includes at least one of a core or a stress applying portion at a position deviated from the central axis,
• wherein each of the plurality of ferrules includes
• a ferrule body retaining the optical fiber, and
• a flange protruding outside from an outer surface of the ferrule body,
• wherein each of the plurality of accommodating portions includes an accommodating wall surface forming an accommodation space accommodating the ferrule, the ferrule being removably fixed to the accommodating wall surface,
• wherein the accommodating wall surface includes an abutting portion, the flange abutting against the abutting portion in the first direction, and
• wherein the accommodating wall surface and the flange are provided with an angle determination mechanism configured to determine a rotation angle of the ferrule around the central axis with respect to the ferrule accommodating component.
