Publication number: 20240085639Abstract: An optical connector ferrule is a member in which an optical fiber is fixed inside a body section, and the distal-end side thereof forms a connection end surface for the optical fiber. An internal space in which the optical fiber is accommodated is formed inside the body section. The internal space runs through from the rear end to the distal end of the body section. An adhesive injection window that is open to the outside is formed in the upper surface of the body section. The adhesive injection window and the internal space are communicated inside the body section via a reduced-diameter section. In plan view, the area (area of the smallest section) of the reduced-diameter section is smaller than the open area of the adhesive injection window.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Takayuki Ando, Masayoshi Tsukamoto
