The present disclosure relates to a multi-fiber optical ferrule that includes a protrusion on the ferrule end face that surrounds and encompasses ferrule microholes on the ferrule end face. The protrusion is shaped and is deformable upon contact with a contact target such that alignment of optical fibers within the ferrule can be controlled. Stated another way, the protrusion enables precision control of the fiber position relative to the ferrule end face.

The present disclosure relates to a fiber optic connector designed to improve the insertion of an optical fiber within the fiber optic connector. The fiber optic connector may include a lead-in tube that makes the insertion of an optical fiber easier. That is, the lead-in tube may be molded over a ferrule hub to fully encapsulate a rear end thereof such that the optical fiber does not snag or hang up during insertion.

A fiber optic ferrule includes a body extending from a first end to a second opposite end, with the body including an axial passage extending between the first and the second ends. The axial passage includes a first diameter portion having a diameter of at least 125 microns, a second diameter portion having a diameter of at least 250 microns and less than a diameter of a buffer, and a smooth and continuous transition between the first and the second diameter portions. The second diameter portion is positioned between the first diameter portion and the second end. The axial passage further defines a tapered shape at the second end extending inward from the second end toward the second diameter portion. In certain embodiments, another smooth and continuous transition can be provided between the taper shape and the second diameter portion. In certain embodiments, the axial passage is smooth and continuous between the first and the second ends of the body. A hub holds the ferrule. A method of assembling a terminated fiber optic cable is also provided.

A fiber optic adapter is disclosed. The fiber optic adapter includes a main body configured to receive a first fiber optic connector through a first end and a second fiber optic connector through a second end for mating with the first fiber optic connector. The adapter includes a ferrule alignment structure located within an axial cavity of the main body, the ferrule alignment structure including a sleeve mount and a ferrule sleeve, the sleeve mount including an axial bore and at least one latching hook extending from a center portion of the sleeve mount toward the first end of the main body and at least one latching hook extending from the center portion toward the second end of the main body, the latching hooks configured to flex for releasably latching the first and second fiber optic connectors to the fiber optic adapter. The sleeve mount and the main body of the fiber optic adapter are unitarily molded as a single piece and the ferrule sleeve is separately placed within the axial bore of the sleeve mount.

The present invention intends to provide a resin composition for an optical connection component capable of achieving both suppression of loss fluctuation due to temperature increase and satisfactory PC connection. The resin composition for an optical connection component includes a base resin and an inorganic filler. A glass transition temperature of the base resin is higher than or equal to 85 C. A mass of a residue obtained by heating the resin composition for the optical connection component at 700 C. is greater than or equal to 68.0% and less than or equal to 74.4% with respect to a mass of the resin composition for the optical connection component. A Rockwell hardness of the resin composition for the optical connection component is greater than or equal to 97.1 and less than or equal to 106.8.
