  • Patent number: 12345914
    Abstract: The present disclosure provides a hollow-core microstructure optical fiber preform, an optical fiber, and a method for manufacturing thereof. An objective of the present disclosure is to introduce a support sheet into a nested structure unit of the hollow-core microstructure optical fiber preform, which not only increases the number of reflection surfaces without increasing the number of nested layers of glass tubes, but also achieves a more accurate positioning by the support sheet and improves manufacturing accuracy as compared to a tangential structure of nested glass tubes, such that the following technical problems, difficulty in controlling a curvature of reflection surfaces, low manufacturing accuracy, large difference between actual loss and theoretical loss, or poor batch consistency, in related anti-resonance optical fibers, caused by increasing the number of layers of nested microstructure units in order to increase the number of reflection surfaces, are solved.
    Type: Grant

  • Patent number: 9933583
    Abstract: An optical fiber connector includes a main body (1), a sleeve (2), and a plug (3). The main body (1) includes a first cube and a second cube that are formed by means of injection molding, where a first cavity (1o) is disposed inside the first cube, and the first cavity (1o) is used to adapt to an optical fiber sub-assembly inserted from a first end face of the first cube; at least two hook-like structures (1n) are formed, by means of injection molding, on the first cube extending from a second end face that is parallel to the first end face into the first cavity (1o), and the hook-like structures (1n) are used to tightly lock the optical fiber sub-assembly when the optical fiber sub-assembly is inserted from the first end face.
